3Blue1Brown is a YouTube channel dedicated to educational content in mathematics and computer science, featuring rich content and in-depth explanations. The channel's videos use animation and graphics to illustrate complex mathematical concepts, making it highly suitable for learners and educators. Ideal for anyone interested in mathematics and computer science.
From registration to actual use - step by step
3Blue1Brown (by Grant Sanderson) is the highest quality math visualization education channel, period. Uses Manim (custom animation engine) to make abstract math intuitive. Search "3blue1brown" on YouTube to subscribe. Essential for learning ML math foundations.
Visit 3Blue1BrownMust-watch series: Essence of Linear Algebra (16 episodes), Essence of Calculus (12 episodes), Differential Equations. These are math foundations for understanding ML algorithms. Grant's visualizations let you "see" the geometric meaning of matrix transformations and gradients.
After watching the linear algebra series, revisiting backpropagation matrix derivations will feel like an "aha" moment. The key step from "memorizing formulas" to "understanding principles".
Recommended: "Neural Networks" series (4 episodes). Grant explains forward and backpropagation from scratch with visualizations. The best neural network intro resource online; after watching, you'll truly understand what "learning" means mathematically.
Read alongside Michael Nielsen's free online book "Neural Networks and Deep Learning". Grant's videos + Nielsen's text is an excellent combination.
Grant also covers: Transformer visualization, GPT principles, probability theory, group theory. To create similar educational animations, learn his open-source Manim engine (github.com/3b1b/manim). Creating concept animations with Manim is an excellent deep learning method.
Try recreating concept animations with Manim. This process forces you to understand every detail—practicing the "Feynman technique": you only truly understand if you can teach it.
