This research introduces "Mistake Attribution (MATT)," a novel task for fine-grained understanding of human mistakes in egocentric videos, encompassing semantic, temporal, and spatial aspects. The paper also presents MisEngine, an automated data generation pipeline, and MisFormer, a unified deep learning model, which together enable scalable and precise mistake analysis, outperforming baselines on new large-scale datasets.
Key insights
- Automated data synthesis through MisEngine can effectively generate ecologically valid and richly annotated mistake datasets, validating the approach to overcome data scarcity for fine-grained tasks.
- A single, unified model (MisFormer) can jointly learn and predict fine-grained semantic, temporal, and spatial mistake attributes, demonstrating improved performance and efficiency over separate, task-specific baselines.
- The projection block in MisFormer, which grounds text semantic role features into video context, is crucial for accurate fine-grained mistake attribution, highlighting the importance of explicit text-video interaction.
