Researchers have introduced Mahalanobis-Based Multi-Head Attention (MHA-CSP), a novel attention mechanism that replaces the standard dot-product with a Mahalanobis distance-based RBF kernel. This approach allows for attention computation in an infinite-dimensional feature space without increasing parameter count. The method enables direct construction of Tree Attention and features an attention meshing mechanism for cross-head kernel collaboration, enhancing accuracy and training efficiency. Experiments show MHA-CSP outperforms Transformer and GCN baselines on long-sequence state tracking tasks. AI
