The Transformer Block Explained: Multi-Head Attention, Residuals, and Layer Norm (Ep:04.03)
Residual connections fix vanishing gradients across depth the same way LSTM gating fixed them across time — both give the gradient a near-identity path. Module 4 of From Zero to…

Learned Q, K, V Explained: What Makes Attention Actually Trainable (Ep:04.02)
Attention only becomes powerful once the query, key, and value projections are learned rather than reused from static embeddings. Module 4 of From Zero to Agents trains a real attention…
