Interactive Visualizations
Playgrounds that make the abstract tangible — tweak the knobs and watch the ideas move.
Matrix Transformations
Watch a 2×2 matrix bend the whole grid of space. See where the basis vectors land, drag your own vector, and spot the eigenvectors — the directions that never turn.
Activation Functions
Compare ReLU, Sigmoid, Tanh, GELU and friends — with their derivatives — and hover to read exact values.
Gradient Descent
Watch an optimizer roll down a loss surface. Tune the learning rate and momentum, drop a starting point, and see it converge or diverge.
Convolution Kernels
Slide a 3×3 kernel over an image and see edge, blur, sharpen and Sobel filters transform it in real time. Edit the kernel yourself.
Bounding Boxes & NMS
See how Non-Maximum Suppression prunes overlapping detections as you drag the IoU threshold.
Self-Attention
Hover a token to see where it attends. Adjust the temperature to sharpen or soften the attention distribution.
