Learning Across Temporal Graph Representation Silos

Temporal graph data are recorded in different representations, but whether these differences also determine the scope of learned knowledge reuse remains unclear. This study investigates whether predictive structure learned from relational histories can be reused between continuous-time dynamic graphs (CTDGs) and tempor...

Where Does Neural Advantage Arise in Continuous-Time Dynamic Graph Prediction?

A mechanism-constrained predictor is constructed that uses pair recurrence, recency and history position, renewal patterns, and short sequential transitions while learning the compatibility within each mechanism to recover a substantial portion of the performance of strong neural baselines, and the recovered performanc...

Warranted Attention: Learning What to Pass from Attention to Prediction

Warrant is proposed, which learns how strongly attention-derived item contributions should be transmitted under the current query, and applies learned item-wise permission before aggregation without renormalization, jointly controlling relative allocation and total transmission mass.

What Softmax Throws Away: Mass-Aware Attention for Evidence Accumulation

Mass-Aware Attention is proposed, which generalizes standard L1 normalization to an Lp family and is positioned as a general normalization principle for improving predictor-facing representation informativeness by controlling repetition invariance in standard attention.
