Researchers introduce DRIFT, a framework that adapts pretrained vision-language models to handle continuous numerical outputs rather than discrete tokens. By combining a base predictor with a flow-matching refinement module, DRIFT improves performance on tasks like temporal localization and robotic control across multiple model architectures.
GIRL-DETR introduces a novel reinforcement learning approach for video moment retrieval that addresses the optimization gap between training losses and evaluation metrics. By freezing backbone networks and applying progressive RL only to detection heads, the method achieves significant accuracy improvements while protecting learned feature representations in lightweight models.
Researchers developed DSMIL-LocNet, a weakly supervised machine learning framework that automates both detection and temporal localization of whale calls in long-duration underwater recordings using only recording-level labels rather than frame-by-frame annotations. The system achieves F1 scores of 0.88-0.91 on recordings up to 30 minutes, significantly outperforming fully supervised baselines that degrade to 0.19-0.64 on the same task.
