What is Attention Mechanism in Applied AI?
A computation that lets a model weigh how much each input token should influence the output for a given position. Self-attention compares every token to every other token, then mixes their representations using those weights. This is the core operation inside a transformer, and it explains both the strength and the cost of the architecture.
Why Attention Mechanism Matters for Your AI or Cybersecurity Career
Attention complexity scales quadratically with context length, which drives most of the engineering work around long-context models, KV cache, and inference cost. It is also the place where many attacks and interpretability methods focus.
