Write the attention score formula before softmax: e_ij = a(s_i, h_j)

How to write a fused softmax kernel in Triton: load row, compute max, subtract, exp, sum, divide

`fused_softmax_kernel(input, output): row_max = max_pool2d(input, row_length); exp_diff = exp(input - row_max); softmax_sum = sum(exp_diff, axis=1); output = exp_diff / softmax_sum`

Why temperature T in softmax(x/T) controls entropy: T→0 is argmax, T→∞ is uniform

As T approaches zero, softmax becomes argmax, maximizing entropy; T→∞ yields uniform distribution, minimizing entropy

What multi-query attention (MQA) is — all Q heads share a single KV head

MQA: Multi-query attention with shared key-value head for efficient cross-query processing

Write the equation for cross-entropy loss

H(y, p) = -Σ(y_i * log(p_i)) for all i

Why attention is O(n²) in sequence length: every token attends to every other token

Attention mechanism's complexity arises from pairwise token interactions, leading to quadratic time complexity

How does attention mechanism in transformer models enhance language understanding and processing by dynamically weighting input tokens during sequence encoding?

Attention mechanisms assign dynamic weights to input tokens, enhancing contextual understanding and sequence processing in transformer models
