Beyond Similarity: Foundation Models as an Efficient Backbone for Training-Free Composed Video Retrieval

Dmitry Demidov, Muhammad Zaigham Zaheer, Omkar Thawakar +2

Composed video retrieval (CoVR) searches a gallery for the target video that realizes a natural-language modification of a source clip. However, at gallery scale, this creates a fu…

Perception Before Supervision: Self-Contained Visual Distillation from Counterfactual Blind Spots

Shravan Venkatraman, Omkar Thawakar, Ritesh Thawkar +2

Self-improvement for multimodal large language models (MLLMs) is typically driven by reward-based methods that provide only coarse scalar feedback. Distillation offers a richer alt…

Ask, Solve, Generate: Self-Evolving Unified Multimodal Understanding and Generation via Self-Consistency Rewards

Ritesh Thawkar, Shravan Venkatraman, Omkar Thawakar +5

Most unified large multimodal models (LMMs) that support both visual understanding and image generation still rely on curated post-training supervision, such as human annotations,…

Paying More Attention to Visual Tokens in Self-Evolving Large Multimodal Models

Shravan Venkatraman, Ritesh Thawkar, Omkar Thawakar +4

Recently, self-evolving large multimodal models (LMMs) have received attention for improving visual reasoning in a purely unsupervised setting. However, multi-role self-play and se…

AgriChain Visually Grounded Expert Verified Reasoning for Interpretable Agricultural Vision Language Models

Hazza Mahmood, Yongqiang Yu, Rao Anwer

Accurate and interpretable plant disease diagnosis remains a major challenge for vision-language models (VLMs) in real-world agriculture. We introduce AgriChain, a dataset of appro…

CoVR-R:Reason-Aware Composed Video Retrieval

Omkar Thawakar, Dmitry Demidov, Vaishnav Potlapalli +5

Composed Video Retrieval (CoVR) aims to find a target video given a reference video and a textual modification. Prior work assumes the modification text fully specifies the visual…

MediX-R1: Open Ended Medical Reinforcement Learning

Sahal Shaji Mullappilly, Mohammed Irfan Kurpath, Omair Mohamed +5

We introduce MediX-R1, an open-ended Reinforcement Learning (RL) framework for medical multimodal large language models (MLLMs) that enables clinically grounded, free-form answers…

Thinking Beyond Labels: Vocabulary-Free Fine-Grained Recognition using Reasoning-Augmented LMMs

Dmitry Demidov, Zaigham Zaheer, Zongyan Han +2

Vocabulary-free fine-grained image recognition aims to distinguish visually similar categories within a meta-class without a fixed, human-defined label set. Existing solutions for…

MATRIX: Multimodal Agent Tuning for Robust Tool-Use Reasoning

Tajamul Ashraf, Umair Nawaz, Abdelrahman M. Shaker +4

Vision language models (VLMs) are increasingly deployed as controllers with access to external tools for complex reasoning and decision-making, yet their effectiveness remains limi…

MIRA: A Novel Framework for Fusing Modalities in Medical RAG

Jinhong Wang, Tajamul Ashraf, Zongyan Han +2

Multimodal Large Language Models (MLLMs) have significantly advanced AI-assisted medical diagnosis, but they often generate factually inconsistent responses that deviate from estab…
