-## Useage
+LLaVAction-0.5B is a multi-modal large language model (MLLM) trained for action recognition. It's based on the Qwen2 language model with a context window of 32K tokens and fine-tuned on the EPIC-KITCHENS-100-MQA dataset. The model takes video input and can answer questions about the actions being performed in the video.  It achieves state-of-the-art performance on the EPIC-KITCHENS-100 Challenge and outperforms GPT-4o by 21 points in accuracy on EPIC-KITCHENS-100-MQA.  It also shows improvements on other action-related video benchmarks such as EgoSchema, PerceptionTest, LongVideoBench, VideoMME and MVBench.
 
-### Intended use
-The model was trained on EPIC-KITCHENS-100-MQA. It's intended to be used on videos that are similar to EPIC-KITCHENS-100.
+## Paper Abstract
 
+Understanding human behavior requires measuring behavioral actions. Due to its complexity, behavior is best mapped onto a rich, semantic structure such as language. The recent development of multi-modal large language models (MLLMs) is a promising candidate for a wide range of action understanding tasks. In this work, we focus on evaluating and then improving MLLMs to perform action recognition. We reformulate EPIC-KITCHENS-100, one of the largest and most challenging egocentric action datasets, to the form of video multiple question answering (EPIC-KITCHENS-100-MQA). We show that when we sample difficult incorrect answers as distractors, leading MLLMs struggle to recognize the correct actions. We propose a series of methods that greatly improve the MLLMs' ability to perform action recognition, achieving state-of-the-art on both the EPIC-KITCHENS-100 validation set, as well as outperforming GPT-4o by 21 points in accuracy on EPIC-KITCHENS-100-MQA. Lastly, we show improvements on other action-related video benchmarks such as EgoSchema, PerceptionTest, LongVideoBench, VideoMME and MVBench, suggesting that MLLMs are a promising path forward for complex action tasks.
