Code a Reinforcement Learning Library in C from Scratch (Full Course)

Learn really to build a complete reinforcement learning model from scratch successful C. The people originates pinch constructing a civilization computational chart and automatic differentiation (autograd) motor to grip matrix operations alongside guardant and backward passes. It past walks done processing a standalone Snake crippled situation from the crushed up, including civilization authorities vector encoding and collision reward logic. Finally, the instruction ties everything together by implementing the REINFORCE argumentation gradient algorithm, trajectory rollouts, and an end-to-end training pipeline to train the agent. 💻 Code: https://github.com/harshbhatt7585/cRL ✏️ Course created by @harshbhatt7585 socials: Twitter: https://x.com/harshbhatt7585 Insta: harshbhatt.ai ⭐️ Chapters ⭐️ - 0:00:00 Introduction & Overview - 0:02:48 Setting Up the Autograd Engine & Variables - 0:16:09 Matrix Creation & Allocation Logic - 0:26:27 Building Nodes & Computational Graph Traversal - 0:56:12 Forward & Backward Activation Operations - 1:04:40 Matrix Multiplication (Row-Major & Transpose Operations) - 1:23:49 Building the Snake Game RL Environment - 1:37:16 State Vector Encoding & Reward System - 1:44:10 Training Pipeline & Rollout Buffers Setup - 1:59:22 Implementing the Actor-Critic Model - 2:07:39 Computing Returns, Advantages & Backward Pass - 2:14:41 Optimizer Step, Evaluation & Conclusion ❤️ Support for this transmission comes from our friends astatine Scrimba – the coding level that's reinvented interactive learning: https://scrimba.com/freecodecamp 🎉 Thanks to our Champion and Sponsor supporters: 👾 @omerhattapoglu1158 👾 @goddardtan 👾 @akihayashi6629 👾 @kikilogsin 👾 @anthonycampbell2148 👾 @tobymiller7790 👾 @rajibdassharma497 👾 @CloudVirtualizationEnthusiast 👾 @adilsoncarlosvianacarlos 👾 @martinmacchia1564 👾 @ulisesmoralez4160 👾 @_Oscar_ 👾 @jedi-or-sith2728 👾 @justinhual1290 -- Learn to codification for free and get a developer job: https://www.freecodecamp.org Read hundreds of articles connected programming: https://freecodecamp.org/news
