Attention Weights Visualization
Graphical technique representing the numerical attention values between tokens in a sequence, using color or size intensities to quantify importance relationships.
Heat Maps
Two-dimensional matrix representation where colors encode the intensity of attention weights, allowing quick identification of areas of high attentional concentration.
Attention Heads Analysis
Comparative study of individual attention patterns in each head of the multi-head mechanism, revealing functional specializations and redundancies between heads.
Multi-Head Attention Patterns
Simultaneous visualization of different attention mechanisms in a Transformer layer, showing how each head captures distinct types of syntactic or semantic relationships.
Self-Attention Matrix
Square matrix representing attention weights between all pairs of tokens in the same sequence, where each element (i,j) indicates the influence of token j on token i.
Cross-Attention Visualization
Graphical representation of attention weights between two different sequences, typically used in encoder-decoder models to visualize source-target alignments.
Attention Rollout
Recursive propagation method of attention weights through successive layers to calculate the cumulative influence of a token on the model's final predictions.
Attention Flow
Visualization technique showing how information flows through Transformer layers by tracing attentional influence paths between tokens.
Gradient-Based Attention
Approach using gradients of the output with respect to attention weights to identify the most relevant contributions to the model's prediction.
Token-to-Token Attention
Direct visualization of pairwise attention relationships between tokens, allowing identification of local and global dependencies in the input sequence.
Layer-wise Attention Analysis
Comparative examination of attention patterns across different network depths, revealing the evolution of abstract representations from lower to upper layers.
Attention Trajectory
Temporal visualization of the evolution of attention weights during inference or training, showing how patterns stabilize or change dynamically.
Attention Saliency Maps
Heatmaps overlaid on the input text to highlight tokens receiving the most attention, facilitating interpretation of the model's decisions.
Attention Propagation
Technique tracing how attention signals propagate and amplify through the network, revealing critical paths for decision-making.
Attention Projection
Dimensional reduction of high-dimensional attention weights to visualizable 2D/3D spaces, using techniques like t-SNE or UMAP to identify clusters of similar patterns.
Attention Clustering
Automatic grouping of similar attention patterns to identify recurring behaviors or functional specializations in attention mechanisms.
Attention Pattern Classification
Automatic categorization of types of attention patterns (syntactic, semantic, positional) based on their structural and distributional characteristics.
