Otter: Mitigating Background Distractions of Wide-Angle Few-Shot Action Recognition with Enhanced RWKV

arXiv — cs.CVWednesday, December 3, 2025 at 5:00:00 AM
  • The introduction of Otter, which utilizes the CompOund SegmenTation and Temporal REconstructing RWKV, addresses the challenges of recognizing actions in wide-angle few-shot action recognition (FSAR) videos by mitigating background distractions. This innovative approach enhances the ability to highlight subjects in complex visual environments, improving overall recognition accuracy.
  • This development is significant as it represents a step forward in the field of artificial intelligence, particularly in video analysis. By effectively segmenting key patches and reconstructing temporal relations, Otter aims to enhance the performance of FSAR systems, which are crucial for applications in surveillance, sports analysis, and human-computer interaction.
  • The advancements in Otter resonate with ongoing efforts in the AI community to refine video understanding techniques. Similar methodologies, such as those seen in ReasonAct and SOAP, emphasize the importance of fine-grained reasoning and spatio-temporal relation capturing, indicating a broader trend towards improving the efficiency and accuracy of action recognition systems across various datasets.

EmbeddingRWKV: State-Centric Retrieval with Reusable States
PositiveArtificial Intelligence
A new retrieval paradigm called State-Centric Retrieval has been proposed, which integrates embedding models and rerankers through reusable states, enhancing the efficiency of Retrieval-Augmented Generation (RAG) systems. This approach involves fine-tuning an RWKV-based large language model to create EmbeddingRWKV, a unified model that optimizes the retrieval process by minimizing redundant computations.
Stuffed Mamba: Oversized States Lead to the Inability to Forget
NeutralArtificial Intelligence
Recent research highlights challenges faced by Mamba-based models in effectively forgetting earlier tokens, even with built-in mechanisms, due to training on contexts that are too short for their state size. This leads to performance degradation and incoherent outputs when processing longer sequences.
