Field Notes
Things I’m reading, deriving, building toward — kept here so I can find them again, and so you can read along.
- May 18, 2026· 35 min
Autoencoders & VAEs, Visualized
A working tour of every operation inside an autoencoder — encoder, bottleneck, decoder, distributions, the reparameterization trick, KL divergence, and the ELBO — built so each step can be watched and replayed.

- Generative
- VAE

The Transformer — Architecture & Mathematics
A from-scratch derivation of the Transformer with worked numeric vectors at every step — token + positional embeddings, scaled dot-product and multi-head attention (with the softmax Jacobian and the √dₖ variance argument), residual + LayerNorm, the GELU feed-forward, causal masking, and cross-attention, traced through full encoder and decoder blocks.

CNN — Architecture & Mathematics
Convolutional networks end to end — the convolution arithmetic with explicit padding, its backward pass as a flipped-kernel convolution, ReLU and BatchNorm, pooling with the receptive-field recurrence, depthwise-separable factorization, and the global-average-pool + softmax classifier head.
