Rubric Rewards from Item Response Theory
Milad Yazdani, Yaser Souri, Xiren Zhou +4
Many language tasks have no single answer that can be checked automatically. Rubrics provide criteria for judging responses to these tasks. For reinforcement learning, the resultin…
WebSTAR: Scalable Data Synthesis for Computer Use Agents with Step-Level Filtering
Yifei He, Pranit Chawla, Yaser Souri +2
Computer use agents (CUAs) can operate real-world digital interfaces but remain difficult to train due to the high cost of graphical user interface (GUI) interaction and the scarci…
Robust Action Segmentation from Timestamp Supervision
Yaser Souri, Yazan Abu Farha, Emad Bahrami +2
Action segmentation is the task of predicting an action label for each frame of an untrimmed video. As obtaining annotations to train an approach for action segmentation in a fully…
FIFA: Fast Inference Approximation for Action Segmentation
Yaser Souri, Yazan Abu Farha, Fabien Despinoy +2
We introduce FIFA, a fast approximate inference method for action segmentation and alignment. Unlike previous approaches, FIFA does not rely on expensive dynamic programming for in…
Hierarchical Graph-RNNs for Action Detection of Multiple Activities
Sovan Biswas, Yaser Souri, Juergen Gall
In this paper, we propose an approach that spatially localizes the activities in a video frame where each person can perform multiple activities at the same time. Our approach take…
On Evaluating Weakly Supervised Action Segmentation Methods
Yaser Souri, Alexander Richard, Luca Minciullo +1
Action segmentation is the task of temporally segmenting every frame of an untrimmed video. Weakly supervised approaches to action segmentation, especially from transcripts have be…
What Object Should I Use? - Task Driven Object Detection
Johann Sawatzky, Yaser Souri, Christian Grund +1
When humans have to solve everyday tasks, they simply pick the objects that are most suitable. While the question which object should one use for a specific task sounds trivial for…
Fast Weakly Supervised Action Segmentation Using Mutual Consistency
Yaser Souri, Mohsen Fayyaz, Luca Minciullo +2
Action segmentation is the task of predicting the actions for each frame of a video. As obtaining the full annotation of videos for action segmentation is expensive, weakly supervi…
Deep Relative Attributes
Yaser Souri, Erfan Noury, Ehsan Adeli
Visual attributes are great means of describing images or scenes, in a way both humans and computers understand. In order to establish a correspondence between images and to be abl…
