Share Center
The share center collects topic pages, playgrounds, and learning routes that are useful to pass around. Its purpose is not to create duplicate pages; it provides stable entry points, suggested context, and short descriptions for readers who want to send technical material to classmates or project teammates.
| Share target | Good use case | Suggested context | Avoid |
|---|---|---|---|
| Topic page | Give a first-time visitor the overall direction. | Explain which articles, code files, and downloads belong to the topic. | Sending an isolated link with no starting point. |
| Playground | Classroom demos, project discussion, or quick concept checks. | Ask the reader to record parameters and outputs, not only watch the animation. | Treating a browser demo as a production model. |
| Download resource | Reproducing C/Python code or data-processing steps. | Attach the related article and runtime boundary. | Running unknown scripts without reading the explanation. |
| Learning route | Give beginners a weekly or topic-level reading order. | Mark what to read first, what to run, and what to verify. | Presenting the route as a certificate-style course promise. |
Remotion animations
Short animations that make algorithm steps visible
These videos are rendered with Remotion and lazy-loaded so the first screen stays fast.
Short animation
CNN Convolution Scan
See how a 3x3 kernel slides, multiplies, sums, and builds a feature map in eight seconds.
Short animation
Matrix Chain Rule
Connect y = Wx + b, MSE loss, and the outer-product form of dL/dW.
Short animation
Backpropagation Graph
Watch the softmax cross-entropy signal move through W2, ReLU, and W1.
Short animation

Compare gradient descent, momentum, and Adam on the same quadratic loss surface.
Short animation
Convolution Receptive Field
Use a 5x5 input and 3x3 kernel to show output size, local windows, and im2col.
Short animation
Attention Heatmap
Put QK^T / sqrt(dk), softmax weights, masking, and KV cache into one matrix view.
