Intuition Behind Attention Weights
When attention weights are nonnegative and sum to , large weights can be interpreted intuitively as a mechanism for the model to select the most relevant components from the available keys. While this provides a helpful conceptual understanding of how the model focuses on certain inputs, it is important to recognize that this is primarily an intuition rather than a strict mechanical rule.

Causal Attention Weight Matrix Calculation
An attention mechanism processes the input sequence:
['The', 'robot', 'grasped', 'the', 'wrench']. The attention weight matrix is calculated to determine the contextual importance of each word. The row in the matrix corresponding to the word 'grasped' has the highest weight value in the column corresponding to the word 'wrench'.
