Preventing accidental struct copies in Go

Prevent dangerous struct copies with noCopy sentinel and go vet's copylock checker. Protect mutexes and sync primitives from value copies.

Sparsely-gated Mixture Of Experts (MoE)

In transformer models, the attention block is typically followed by a feed forward layer (FF), which is a simple fully-connected NN with a hidden layer and nonlinearity. Here's the code for such a block that uses ReLU: def feed_forward_relu(x, W1, W2): """Feed-...

Cross-entropy and KL divergence

Cross-entropy is widely used in modern ML to compute the loss for classification tasks. This post is a brief overview of the math behind it and a related concept called Kullback-Leibler (KL) divergence. Information content of a single random event We'll start with a single event...
