AttentionViG: Cross-Attention-Based Dynamic Neighbor Aggregation in Vision GNNs

This work proposes a cross-attention-based aggregation method in which the query projections come from the node, while the key projections come from its neighbors, and introduces a novel architecture called AttentionViG that uses the proposed cross-attention aggregation scheme to conduct non-local message passing.

Ceiling of a Task: When Can a Transformer Succeed Without Its Chain of Thought?

Reasoning models generate long chains of thought before they answer, yet it is debated whether the content of these chains does real computational work or is largely decorative. We study this question by viewing a transformer as a shallow circuit. One forward pass through a fixed number of layers has constant depth, so...
