Stealth Is a Relation, Not a Property: How Event Representations Create Blind Spots for Timing Attacks in Event-Based Perception

An event camera produces an asynchronous stream, but what is visible in that stream depends on how a downstream consumer, such as a model or detector, processes time. The same timestamp change may leave a coarse temporal representation unchanged while changing the response of a model that preserves finer timing. We cha...

On The Robustness-Resolution Tradeoff In Temporal Quantization Of Event Streams

This work defines a class of nonnegative, mass-preserving, resolution-faithful continuous encoders and proves that every encoder in this class has global L1 sensitivity at least 2/Delta, where Delta denotes bin width, and shows that linear two-bin interpolation attains this limit.

The Ceiling Is in the Channel: Auditing Learner Gaps and Measurement Frontiers in Clinical Prediction

A PRISMA-guided synthesis of 104 clinical tasks shows that the same channel-level regularities recur across more than 18 disease categories: a broad but non-universal structured-clinical region, diminishing same-channel gains across model families, and higher performance when measurement channels change.
