[Help Needed] Developing an AI to Play Mini Metro – Struggling with Data Extraction & Strategy method

Hello everyone ! First of all, please excuse my English if i do mistakes, as it is not my native language and I am not necessarily comfortable with it :) Regarding this project, I will explain my initial intention. I know very little about coding, but I enjoy it and have had some Python lessons, along with a few small personal projects for fun, mostly using YouTube tutorials. Nothing too advanced... However, now I want to take it to the next level. Since I have some familiarity with coding, I’ve wanted to work on artificial intelligence for a while. I have never coded AI myself, but I enjoy downloading existing projects (for chess, checkers, cat-and-mouse games, etc.), testing their limits, and understanding how they work. One of my favorite strategy game genres is management games, especially Mini Metro. Given its relatively simple mechanics, I assumed there would already be AI projects for it. But to my surprise, I could only find mods that add maps ! I admit that I am neither the best nor the most patient researcher, so I haven’t spent hours searching, but the apparent lack of projects for this game struck me. Maybe the community is just small ? I haven't looked deeply into it. So, I got it into my head to create my own AI. After all, everything is on the internet, and perseverance is key ! However, perseverance alone is not enough when you are not particularly experienced, so I am turning to the community to find knowledgeable people who can help me. The First Obstacle: Getting Game Data I quickly realized that the biggest challenge is that Mini Metro does not have an accessible API (at least, not one I could find). This means I cannot easily extract game data. My initial idea was to have an AI analyze the game, think about the best move, and then write out the actions to be performed, instead of coding a bot that directly manipulates the game. But first, I needed a way to retrieve and store game data. Attempt #1: Image Recognition (Failed) Since there was no API, I tried using image recognition to gather game data. Unfortunately, it was a disaster. I used mss for screenshots ,Tesseract for OCR, andNumPy to manipulate images in the HSV color space but it produced unreliable results : It detected many false positives (labeling empty spaces as stations) It failed to consistently detect numbers (scores or resources like trains and lines) Dotted bridge indicators over rivers were misinterpreted as stations While I could detect stations, lines, and moving trains, the data was chaotic and unreliable Attempt #2: Manual Data Entry (Partially Successful but Impractical) Since image recognition was unreliable, I decided to manually update the game data in real-time. I created a script that : Displays an overlay when I press Shift+R. Allows me to manually input stations, lines, and other game elements. Saves the current state when I press Shift+R again, so I can resume playing. Implements a simple resource management system (trains, lines, etc.). This works better than image recognition because I control the input, but I’m running into serious limitations : Some game mechanics are hard to implement manually (adding a station in the middle of a line, extending the correct line when two lines overlap at a station) Keeping track of station demands (the shapes passengers want to travel to) becomes overwhelming as the game progresses Updating the score in real-time is practically impossible manually, and the score is essential for training an AI (for my reward systems) My Dilemma At this point, I am unsure of how to proceed. My questions for the community : Am I going in the right direction? Should I continue improving my manual tracking system or is it a dead end? Should I have persevered with image recognition instead? Is there a better way to extract game data that I haven’t thought of? I would appreciate any guidance or ideas. Thanks in advance ! if you need more info, i have posted my codes here : https://github.com/Dmsday/mini\metro\data\analyzer (for the image detection version I'm not sure that it's the latest version aka the most "functional" version that I could do because I think I deleted it out of boredom...)

How do byte-level language models work?

I've recently been trying to pre-train my own small language model on the tiny-series datasets on huggingface: https://huggingface.co/collections/nampdn-ai/tiny-series-6503910fd491144159519c70. I also wanted to use a model similar to MEGABYTE: https://arxiv.org/pdf/2305.07185.pdf, but I don't understand how using bytes would work. The only implementation I could find: https://github.com/lucidrains/MEGABYTE-pytorch used str(chr(max(32, token))) to decode any token (byte) to a character and put the embedding size as 256. Firstly, why 256 and not 256-32 as any values below 32 are ignored? Also, many byte-level models including this and ByteT5 mention that they can process any text sequence even in a multilingual setting, however how would that be true if we are only using one byte, would we have to move to 2 bytes or use an UNK token, and if we did use 2 bytes that would make our embedding size around 65000 which defeats sort of the point as one of the advantages mentioned is that we are able to use a small embedding matrix? Furthermore, most language models add special tokens like bos, eos, unk and even for llama they use beginning of instruction, end of instruction, and more for system instructions, response, context... Should I use something like this as my dataset has some structures where there is a context, instruction and response, and if i did how would I add these if I'm using byte-level encodings? Final questions: Firstly, for the datasets mentioned including code,stories,webtext,... would I tokenise all of these datasets then concatenate them to then randomly sample from, or should i train seperately on each as some like code and webtext are much larger than the others? Finally, for the webtext part of the dataset, there is a passage of text then a passage analysing the text (main ideas,purpose,...), how should I encode this, should I use an extra ANALYSE token or just concatenate? Thank you for reading this far, I am sort of a beginner so if I said something stupid please point it out. Also, if there were unclear parts in my question I'm sorry as I struggled how to word these questions. Any help would be appreciated!

Full free course on self-driving cars (no libraries)

My beginner-friendly artificial intelligence course is now complete: https://www.youtube.com/playlist?list=PLB0Tybl0UNfYoJE7ZwsBQoDIG4YN9ptyY You will learn the inner workings of a self-driving car system and how to implement the driving mechanics, the artificial sensors, the collision detection and the neural networks . We study fundamental techniques like linear interpolation and segment intersection which are valuable in countless other applications and of course, neural networks, which are responsible for most AI systems nowadays. I made the course for coders, to bridge the gap between typical programming and AI. We don't use any libraries and implement every component from scratch to understand how such a system works. But I give pointers to libraries during the course if you want to take things one step further!

Well, I'm starting to read som reaserch paper and to truth I haven't read any till now.

So I have just finished deeplearning.ai course 1and wanted to see som reasrech papers regarding suprivised learning as beginner So, the vetrans of ML can you please suggest some papers for me that I can re-implement on my own.

Scratch Machine Learning Algorithms Implementations

Hi there, other Redditors! Like many of you, when I first started working in the AI field, I wanted to build some basic Machine Learning models from scratch in order to better understand how each algorithm works, improve my programming and math skills, or simply produce an eye-catching, difficult project to put in the résumé. After spending some time searching for resources that could help me guide my studies, I discovered that the majority of scratch implementations that are currently available are either i) outdated (having been implemented years ago using Python 2 or an earlier version of Python 3); ii) too difficult to understand (using a lot of difficult, unfriendly optimization techniques or with poorly written code); or iii) too simple (only covering binary classification). With that in mind, I made the decision to develop user-friendly, uncomplicated, organized, and simple implementations from scratch. Aside from all of that, I've always wanted to create an open-source project so that others, particularly novices and those with less than a year's experience (like me), can collaborate with others, contribute to public projects, and experience Git firsthand (some of these implementations were made by other contributors!). Here are some implementations that are available: Algorithms (Random Forest Classifier and Regressor, Decision Tree Classifier and Regressor, KMeans, KNN Classifier and Regressor, Gaussian Naive Bayes, Linear Regression, Logistic Regression, PCA, Perceptron, MLP Classifier and Regressor, SVM Classifier and Regressor); Regression and classification metrics; Distance metrics (such as Euclidean); Data split functions (such as KFold); Activation and loss functions; Scalers (such as MinMaxScaler) and encoders (such as One Hot Encoder); and a few things more! Project's link: https://github.com/rafaelgreca/scratchml Disclaimer: The goal of this library is to provide code that is simpler, easier to understand, and more approachable for artificial intelligence enthusiasts and beginners who want to contribute to an open-source repository or who want to learn more about how algorithms work. It is not meant to replace existing libraries that are better, more optimized, and have a wider variety of implemented algorithms (such as scikit-learn, PyTorch, Keras, and Tensorflow). If you want to use optimized implementations with accurate results, please use one of the previously mentioned libraries. P.S.: I accidentally deleted the other post, so I am posting again. :-)

Teaching an AI to Play Mario: A Learning Journey

TLDR: I've always wanted to learn reinforcement learning, but the notation and concepts often seemed overwhelming (and scary). So, \~3 months ago, I set myself a challenge: Train an AI to Speedrun Mario Watch the progression here: https://youtu.be/OQitI066aI0 ​ Full Story: Three months ago, I stared at the dense forest of Reinforcement Learning (RL) papers and felt like Mario facing Bowser for the first time: unequipped and overwhelmingly outmatched. The notation seemed like hieroglyphics, and terms like "policy gradients" felt like they belonged in a sci-fi novel, not a beginner's project. But RL always seemed so cool, and I was really determined to achieve my goal. So, I started with the Sutton & Barto RL textbook, learning things like the Multi-Armed Bandit problem and MDPs working my way up to Actor-Critic methods. That book is literal gold & I highly recommend you work through it (even though it can be tough at times). I tried everything from random courses online to books on amazon & this textbook has been by far the most clear and effective way to learn RL. The biggest issue with the textbook is you learn a lot of theory, but don't learn implementation. So, I would go through a chapter a week & set aside Friday + the weekend to actually implement what I learned (usually by watching youtube tutorials & looking at Github Repos). Eventually, while searching for practical resources for implementing PPO, I stumbled upon a GitHub repository that literally trained an AI to play Mario. Rather than just cloning and running the code, I took a deeper approach. I aimed to understand the repository thoroughly, ensuring each line of code made sense in the context of what I had studied. But of course, this wasn't easy. One of the biggest issues was my hardware limitation. I was working on an old Mac. So, I started using Google Collab, but that had its own problems (session timeouts & limited GPU access). Ultimately, I found AWS Sagemaker to be pretty good. ​ After rewriting the code, I felt confident it would work because I understood every aspect of it. So, I trained the AI to play Mario across a variety of different levels (took a long time and a lot of trial and error with the learning rate). It feels amazing seeing your theoretical knowledge translate into tangible results & this project gave me a big confidence boost. ​ Anyways I made a video showing off the results (Note that I simplified the technical parts for it to reach a wider audience): https://youtu.be/OQitI066aI0 ​ Feel free to drop any questions or feedback, I'm more than happy to help or chat about my experiences. I hope my journey can inspire some of you who might be feeling overwhelmed with the idea of diving into reinforcement learning or any other area of AI. Remember, the hardest part is often taking the first step. Once you start, the momentum will carry you forward. Thank you for reading my super long post and sharing in my little success story! 🚀🕹️🎮

How to build a simple Neural Network from scratch without frameworks. Just Math and Python. (With lots of animations and code)

Hi ML community! I've made a video (at least to the best of my abilities lol) for beginners about the origins of neural networks and how to build the simplest network from scratch. Without frameworks or libraries, just using math and python, with the objective to get people involved with this fascinating topic! I tried to use as many animations and manim as possible in the making of the video to help visualizing concepts :) The video can be seen here Building the Simplest AI Neural Network From Scratch with just Math and Python - Origins of AI Ep.1 (youtube.com) It covers: The origins of neural networks The theory behind the Perceptron Weights, bias, what's all that? How to implement the Perceptron How to make a simple Linear Regression Using the simplest cost function - The Mean Absolute Error (MAE) Differential calculus (calculating derivatives) Minimizing the Cost Making a simple linear regression I tried to go at a very slow pace because as I mentioned, the video was done with beginners in mind! This is the first out of a series of videos I am intending to make. (Depending of course if people like them!) I hope this can bring value to someone! Thanks!

Scikit-learn vs Statsmodel Linear regression is often the first model introduced to those stepping into the world of data science and machine learning. A deep understanding of this fundamental concept is crucial for building a solid foundation. In this post, I explore two widely used approaches to linear regression, each with distinct purposes: 1️⃣ 𝗦𝗰𝗶𝗸𝗶𝘁-𝗟𝗲𝗮𝗿𝗻’𝘀 𝗟𝗶𝗻𝗲𝗮𝗿 𝗥𝗲𝗴𝗿𝗲𝘀𝘀𝗶𝗼𝗻: Optimized for machine learning applications and large datasets, this model focuses on efficiency and scalability. 2️⃣ 𝗦𝘁𝗮𝘁𝘀𝗺𝗼𝗱𝗲𝗹𝘀’ 𝗢𝗿𝗱𝗶𝗻𝗮𝗿𝘆 𝗟𝗲𝗮𝘀𝘁 𝗦𝗾𝘂𝗮𝗿𝗲𝘀 (𝗢𝗟𝗦): Known for its comprehensive statistical insights, this approach provides a detailed report ideal for understanding relationships and diagnosing issues like multicollinearity.

Sophomore computer science student, looking at ISLP vs ESL vs mlcourse.ai

For background, I am currently a computer science sophomore, with intermediate skills in Python and C++. I have taken university courses on data structure and algorithms, calc 1-3, linear algebra, and an introductory stat course (which covered confidence interval, Z and T sample test, and hypothesis testing). I also have read up to Chapter 5 of the MML book and am currently self-studying probability theory (through STAT 110 video and textbook by Joe Blitzstein). I have done a few beginner ML projects with Tensorflow and scikit-learn, but most of the work is in EDA and feature engineering, while the ML model is just a black box that I plug and chug. So now, I want to learn how to implement ML models from scratch. I've been skimming over ISLP, which many people online recommended, but it seems that while it talks about mathematical equations used, I don't really get to implement it; as the labs are a lot of importing an already implemented model then plug and chug. So now, I am looking at ESL, which I believe is the more detailed and mathematically rigorous version of ISL. However, there aren't any labs or code along to ease beginners in (which I somewhat understand given the intended audience of the book). Another option I am looking at is mlcourse.ai, which seems to cover mathematics and has some lab/code along for it. But it doesn't seem to span as many subjects as ESL does. Given these options, I am unsure of which one to pick, should I first finish my self-study on probability theory and then Chapters 6-8 of MML? Then should I do ISLP first or just get into ESL? Or maybe I should do mlcourse.ai first then into ESL? Or should I just do the ML course/book along with the maths? In addition, there is also the data science + feature engineering stuff which I wonder if I should study more about. Sorry if this seems like a mess, there are just so many things to ML that I am kinda overwhelmed.

Advice Needed

Hey everyone, I’ve been diving into Artificial Intelligence, Machine Learning, and Deep Learning recently, but I find myself a little confused about how to approach the learning process effectively. My goal isn’t just to secure a job but to actually build cool AI products or startups—something innovative and impactful, like what companies such as OpenAI, Anthropic, or ElevenLabs are doing. I often see founders or engineers building incredible AI-driven startups, and I can’t help but wonder: • What kind of learning path did these people follow? • Surely they didn’t just stick to basic Udemy or YouTube courses that most people use for job prep. • What resources or approaches do serious AI practitioners use? I’ve heard that implementing research papers is a great way to gain a deep, intuitive understanding of AI concepts. But as someone who is still a beginner, I’m unsure how to start implementing papers without feeling overwhelmed. Here’s what I’m hoping to get clarity on: Where should I begin as a complete beginner? What resources, projects, or habits would you recommend to build solid fundamentals in AI/ML? How do I progress from beginner to a level where I can implement research papers? Are there intermediate steps I need to take before diving into papers? What would the ideal roadmap look like for someone who wants to build startups in AI? If you’re an AI practitioner, researcher, or startup founder, I’d love to hear about your experiences and learning pathways. What worked for you? What didn’t? Any advice or resources would be immensely appreciated. I’m ready to put in the hard work, I just want to make sure I’m moving in the right direction. Thanks in advance! Looking forward to learning from this community.

Is it worth doing a Msc Conversion course

I’m a philosophy student currently, graduating with a 2.1 from a russell group uni. I’m looking for a career change into ML with the ultimate goal being research, whether it be comp neuro, biology, or using it in sports. I’ve found a Msc conversion course (1 year with no CS background required) where, as the name suggests, they teach you AI and ML techniques and how to implement them in a a real world context. It also includes a 3 month dissertation project with the possibility of working with industry. I was speaking to a friend today who suggested I learn on my own and save the money. I couldn’t help but think a qualification is useful alongside a portfolio, rather than just a portfolio (which he suggested). Given my current situation, a beginner programmer looking for a way in, what do you think I do?

Looking for the Best Resources to Level Up in Python, AI, ML, and Data Science!

Hey everyone, I've been diving into AI, ML, and Data Science for a while now and have completed the IBM AI Engineering Course and the Machine Learning Specialization by Andrew Ng on Coursera. Both were super helpful to get me started on beginner-level implementation. However, I'm really looking to take my skills to the next level and go pro! 🎯 I’m looking for awesome from 0 to total hero tutorials/coding videos, especially on YouTube, and the best books you’ve come across. I'm particularly interested in: Python for AI/ML/Data Science Advanced AI/ML topics (hands-on projects would be a plus!) Awesome books (I already have a PDF of O'Reilly's Data Science* book with the black and yellow reptile on the cover and just started reading that since its a bit pricy in India) Any recommendations for resources (free or affordable if possible) would be amazing. Also, if anyone could suggest a solid book for Java Data Structures and Algorithms, that’d be awesome. I already know the concepts but want something to keep on hand for reference. Thanks a ton in advance for any suggestions! 🙌

NeRFs (2025)

Hey everyone! I'm currently working on my final year project, and it's focused on NeRFs and the representation of large-scale outdoor objects using drones. I'm looking for advice and some model recommendations to make comparisons. My goal is to build a private-access web app where I can upload my dataset, train a model remotely via SSH (no GUI), and then view the results interactively — something like what Luma AI offers. I’ll be running the training on a remote server with 4x A6000 GPUs, but the whole interaction will be through CLI over SSH. Here are my main questions: Which NeRF models would you recommend for my use case? I’ve seen some models that support JS/WebGL rendering, but I’m not sure what the best approach is for combining training + rendering + web access. How can I render and visualize the results interactively, ideally within my web app, similar to Luma AI? I've seen things like sMPLerNeRF, SNeRFs, and Instant-NGP, but I’m curious if there are more beginner-friendly or better-documented alternatives that can integrate well with a custom web interface. Any guidance on how to stream or render the output inside a browser? I’ve seen people use WebGL/Three.js, but I’m still not clear on the pipeline. I’m still new to NeRFs, but my goal is to implement the best model I can, and allow interactive mapping through my web application using data captured by drones. Any help or insights are much appreciated!

Neural Networks you can try to implement from scratch (for beginners)

I was reading a tweet talking about how useful it is to implement neural networks from scratch. How it allowed for a greater understanding of the topic. The author said he found it more useful than other people explaining the concept to him. While I disagree with the author’s opinion that it stops the need for explanations. It certainly does help the understanding of one’s model. I recommend giving it a go. In the blog post, I will suggest which models you should try to implement from scratch using NumPy or your favourite library. Also, I will link to some accompanying resources. Simple Feedforward Network This is the most famous example because it’s so simple. But allows you to learn so much. I heard about this idea from Andrew Trask. It also helped me think about implementing networks from scratch in general. In the Feedforward network, you will be using NumPy. As you won't need Pytorch or TensorFlow. To do the heavy-lifting for complex calculations. You can simply create a Numpy Array for training and testing data. You can also create a nonlinear function using Numpy. Then work out the error rate between the layer’s guess and real data. Resource for this task: https://iamtrask.github.io/2015/07/12/basic-python-network/ Follow this tutorial. It does a much better job of explaining how to do this in NumPy. With code examples to follow. Feedforward Network with Gradient Descent This is an extension of the network above. In this network, we allow the model to optimise its weights. This can also be done in NumPy. Resource for this task: https://iamtrask.github.io/2015/07/27/python-network-part2/ A follow-on from the previous article. Pytorch version of Perceptrons and Multi-layered Perceptrons. Here will go up a level by using a library. Examples I'm using will be done in Pytorch. But you can use whatever library you prefer. When implementing these networks, you learn how much a library does the work for you. Recourses for the task: https://medium.com/@tomgrek/building-your-first-neural-net-from-scratch-with-pytorch-56b0e9c84d54 https://becominghuman.ai/pytorch-from-first-principles-part-ii-d37529c57a62 K Means Clustering Yes, this does not count as a neural network. But a traditional machine learning algorithm is still very useful. As this is non deep learning algorithm it should be easier to understand. This can be done just using NumPy or Pandas depending on the implementation. Recourse for this task: https://www.machinelearningplus.com/predictive-modeling/k-means-clustering/ http://madhugnadig.com/articles/machine-learning/2017/03/04/implementing-k-means-clustering-from-scratch-in-python.html https://gdcoder.com/implementation-of-k-means-from-scratch-in-python-9-lines/ There are quite a few choices to choose from. So pick whatever implementation helps you understand the concepts better. These networks or models should be simple enough that you won't get lost trying to implement them. But still, help learn a few stuff along the way. \- If you found this post useful, then check out my mailing list where I write more stuff like this.

Learning Resources + Side Project Ideas

I made a post last night about my journey to landing an AI internship and have received a lot of responses asking about side projects and learning resources, so I am making another thread here consolidating this information for all those that are curious! Learning Process Step 1) Learn the basic fundamentals of the Math USE YOUTUBE!!! Literally just type in 'Machine Learning Math" and you will get tons of playlists covering nearly every topic. Personally I would focus on Linear Algebra and Calculus - specifically matrices/vector operations, dot products, eigenvectors/eigenvalues, derivatives and gradients. It might take a few tries until you find someone that meshes well with your learning style, but 3Blue1Brown is my top recommendation. I also read the book "Why Machines Learn" and found that extremely insightful. Work on implementing the math both with pen and paper then in Python. Step 2) Once you have a grip on the math fundamentals, I would pick up Hands-on Machine Learning with Sci-kit Learn, Keras and TensorFlow. This book was a game changer for me. It goes more in depth on the math and covers every topic from Linear Regression to the Transformers architecture. It also introduces you to Kaggle and some beginner level side projects. Step 3) After that book I would begin on side projects and also checking out other similar books, specifically Hands on Large Language Models and Hands on Generative AI. Step 4) If you have read all three of these books, and fully comprehend everything, then I would start looking up papers. I would just ask ChatGPT to feed you papers that are most relevant to your interests. Beginner Side Project Ideas 1) Build a Neural Network from scratch, using just Numpy. It can be super basic - have one input layer with 2 nodes, 1 hidden layer with 2 nodes, and output layer with one node. Learn about the forward feed process and play around with different activation functions and loss functions. Learn how these activation functions and loss functions impact backpropagation (hint: the derivatives of the activation functions and loss functions are all different). Get really good at this and understand the difference between regression models and classification models and which activation/loss functions go with which type of model. If you are really feeling crazy and are more focused on a SWE type of role, try doing it in a language other than python and try building a frontend for it so there is an interface where a user can input data and select their model architecture. 2) Build a CNN Image Classifier for the MNIST - Get familiar with the intricacies of CNN's, image manipulation, and basic computer vision concepts. 3) Build on top of open source LLM's. Go to Hugging Face's models page and start playing around with some. 4) KAGGLE COMPETITIONS - I will not explain further, do Kaggle Competitions. Other Resources I've mentioned YouTube, several books and Hugging Face. I also recommend: DataLemur.com \- Python practice, SQL practices, ML questions - his book Ace the Data Science Interview is also very good. X.com \- follow people that are prominent in the space. I joined an AI and Math Group that is constantly posting resources in there deep-ml.com If you have found any of this helpful - feel free to give me a follow on X and stay in touch @ x.com/hark0nnen\

Implementation of AI and Machine Learning In The Healthcare Industry

Using AI in medical diagnostics can assist physicians in enhancing medical therapies in a variety of ways. Physical burnout because of overwork is a severe problem that many medical professionals experience these days. It reduces medical practitioners’ overall performance, which leads to an increase in diagnostic inaccuracy. The most recent Medscape National Physician Burnout and Suicide Report 2020 data highlighted the risks of putting too much pressure on physicians, particularly those juggling families, retirement plans, and the intricacies of their employment. What is your thought on implementing AI/ML in the medical sector? Do you believe it's a threat to the medical workers?

[Help Needed] How to tackle AI for DNS Security in a Hackathon for Beginner.

Hi everyone! I've been selected to participate in an AI and Cybersecurity Hackathon, and the group I'm in focuses on AI for DNS Security. Our goal is to implement AI algorithms to detect anomalies and enhance DNS security. Here’s the catch: I have no prior background in cybersecurity, and I’m also a beginner in applying AI to real-world security problems. I’d really appreciate some guidance from this amazing community on how to approach this challenge. A bit more about the project: Objective: Detect anomalies in DNS traffic (e.g., malicious requests, tunneling, etc.). AI tools: We’re free to choose algorithms, but I’m unsure where to start—supervised vs. unsupervised learning? My skillset: Decent grasp of Python (Pandas, Scikit-learn, etc.) and basic ML concepts. No practical experience in network security or analyzing DNS traffic. What I’m looking for: Datasets: Any recommendations for open-source DNS datasets or synthetic data creation methods? AI methods: Which models work best for anomaly detection in DNS logs? Are there any relevant GitHub projects? Learning resources: Beginner-friendly material on DNS security and the application of AI in this domain. Hackathon tips: How can I make the most of this opportunity and contribute effectively to my team? Bonus question: If you’ve participated in similar hackathons, what strategies helped you balance learning and execution within a short timeframe? Thank you so much in advance for any advice, resources, or personal experiences you can share! I’ll make sure to share our project results and lessons learned after the hackathon.

Best AI/ML course for Beginners to advanced - recommendations?

Hey everyone, I’m looking for some solid AI/ML courses that cover everything from the basics to advanced topics. I want a structured learning path that helps me understand fundamental concepts like linear regression, neural networks, and deep learning, all the way to advanced topics like transformers, reinforcement learning, and real-world applications. Ideally, the course(s) should: • Be beginner-friendly but progress to advanced topics • Have practical, hands-on projects • Cover both theory and implementation (Python, TensorFlow, PyTorch, etc.) • Be well-structured and up to date I’m open to free and paid options (Coursera, Udemy, YouTube, etc.). What are some of the best courses you’d recommend? Thanks in advance!

Easy small implementations of AI

I think everyone secretely (or not secretly) love small implementations with training examples, dataset preprocessing etc in just a small colab notebook. Why do almost everyone create big github repositories with tones of code just for a not-that-big model ? Maybe it's just me who isn't able to find small notebooks? Does anyone has source with extremely useful small notebooks?
