Thinking With Bounding Boxes: Enhancing Spatio-Temporal Video Grounding via Reinforcement Fine-Tuning

ReMatch has been introduced as a new framework that utilizes the generative capabilities of Multimodal Large Language Models (MLLMs) for enhanced multimodal retrieval. This approach trains the MLLM end-to-end, employing a chat-style generative matching stage that assesses relevance from various inputs, including raw data and projected embeddings.

A new benchmark called CaptionQA has been introduced to evaluate the utility of model-generated captions in supporting downstream tasks across various domains, including Natural, Document, E-commerce, and Embodied AI. This benchmark consists of 33,027 annotated multiple-choice questions that require visual information to answer, aiming to assess whether captions can effectively replace images in multimodal systems.

LLaVA-UHD v3 has been introduced as a new multi-modal large language model (MLLM) that utilizes Progressive Visual Compression (PVC) for efficient native-resolution encoding, enhancing visual understanding capabilities while addressing computational overhead. This model integrates refined patch embedding and windowed token compression to optimize performance in vision-language tasks.

A new training framework named Monet has been introduced to enhance multimodal large language models (MLLMs) by enabling them to reason directly within latent visual spaces, generating continuous embeddings as intermediate visual thoughts. This approach addresses the limitations of existing methods that rely heavily on external tools for visual reasoning.

CAPability has been introduced as a comprehensive visual caption benchmark designed to evaluate the correctness and thoroughness of captions generated by multimodal large language models (MLLMs). This benchmark addresses the limitations of existing visual captioning assessments, which often rely on brief ground-truth sentences and traditional metrics that fail to capture detailed captioning effectively.

A new framework called BHD-RAG has been proposed to enhance the diagnosis of Birt-Hogg-Dube syndrome (BHD) by integrating multimodal retrieval-augmented generation with deep learning methods. This approach addresses the challenges of limited clinical samples and low inter-class differentiation among Diffuse Cystic Lung Diseases (DCLDs) in CT imaging, aiming to improve diagnostic accuracy significantly.

A new method called Vision-Guided Attention (VGA) has been proposed to mitigate hallucinations in Multimodal Large Language Models (MLLMs) by enhancing their visual attention capabilities. VGA constructs precise visual grounding from visual tokens and guides the model's focus to relevant areas during inference, improving accuracy in tasks like image captioning with minimal latency.

Waymo has introduced WaymoQA, a new dataset comprising 35,000 human-annotated question-answer pairs designed to enhance safety-critical reasoning in autonomous driving through multi-view inputs. This initiative aims to address the complexities of high-risk driving scenarios where traditional single-view approaches fall short.
