Action-Agnostic Point-Level Supervision for Temporal Action Detection

AAAI 2025technical

We propose action-agnostic point-level (AAPL) supervision for temporal action detection to achieve accurate action instance detection with a lightly annotated dataset. In the proposed scheme, a small portion of video frames is sampled in an unsupervised manner and presented to human annotators, who…

Lower-Bounded Proper Losses for Weakly Supervised Classification

ICML 2021spotlight

This paper discusses the problem of weakly supervised classification, in which instances are given weak labels that are produced by some label-corruption process. The goal is to derive conditions under which loss functions for weak-label learning are proper and lower-bounded—two essential requiremen…
