This research introduces a new benchmark and synthetic dataset to address the critical data gap in training video LLMs for proactive mistake correction during real-world tasks. By leveraging counterfactual synthetic data, the study demonstrates significant performance gains for smaller, edge-deployable models, highlighting a viable path toward practical task guidance assistants. The work underscores that current state-of-the-art video LLMs struggle with reactive intervention due to a lack of training examples featuring mistakes and timely corrections.
Streaming Interventions: Can Video Large Language Models Correct Mistakes as They Occur?
arXiv:2606.09547v1 Announce Type: cross Abstract: Learning everyday skills, like cooking a dish, relies increasingly on instructional media such as online videos. This opens the door to the use of video (and multimodal) large language models (LLMs) as task guidance assistants. A crucial capability for the real-world success of a prospective task guidance assistant is it's ability to intervene proactively as soon as a mistake is apparent in order to guide the user. To evaluate this crucial capability, we introduce Ego-MC-Bench (Mistake Corrections), a benchmark for evaluating reactive, step-by-step task guidance in realistic cooking scenarios. Extensive experiments show that Ego-MC-Bench is highly challenging for state-of-the-art video LLMs. We argue that a key reason is the limited availability of training data for fine-tuning models on this task. Although there exists a wide range of cooking video datasets, existing datasets lack examples of mistakes along with appropriately timed interventions. To help address this data limitation, we also introduce Ego-CoMist, a counterfactual synthetic dataset created by transforming non -interactive cooking videos into supervised training examples showing proactive interventions. We show that fine-tuning on Ego-CoMist yields performance gains especially for smaller and more efficient video LLMs that are well suited for delivering assistance on edge devices.
