Waking Up Blind: Cold-Start Optimization of Supervision-Free Agentic Trajectories for Grounded Visual Perception
Ashutosh Bajpai, Tamal Majumder, Akshay Nambi +1
Small Vision-Language Models (SVLMs) are efficient task controllers but often suffer from visual brittleness and poor tool orchestration. They typically require expensive supervise…
Markovian ODE-guided scoring can assess the quality of offline reasoning traces in language models
Arghodeep Nandi, Ojasva Saxena, Tanmoy Chakraborty
Reasoning traces produced by generative language models are increasingly used for tasks ranging from mathematical problem solving to automated fact checking. However, existing eval…
Understanding the Physics of Key-Value Cache Compression for LLMs through Attention Dynamics
Samhruth Ananthanarayanan, Ayan Sengupta, Tanmoy Chakraborty
As context windows in LLMs scale to 100K+ tokens, the key-value (KV) cache becomes the dominant memory bottleneck, with recent methods claiming 80-90% savings and minimal benchmark…
Do You Know About My Nation? Investigating Multilingual Language Models' Cultural Literacy Through Factual Knowledge
Eshaan Tanwar, Anwoy Chatterjee, Michael Saxon +3
Most multilingual question-answering benchmarks, while covering a diverse pool of languages, do not factor in regional diversity in the information they capture and tend to be West…
HIDE and Seek: Detecting Hallucinations in Language Models via Decoupled Representations
Anwoy Chatterjee, Yash Goel, Tanmoy Chakraborty
Contemporary Language Models (LMs), while impressively fluent, often generate content that is factually incorrect or unfaithful to the input context - a critical issue commonly ref…
Rank, Chunk and Expand: Lineage-Oriented Reasoning for Taxonomy Expansion
Sahil Mishra, Kumar Arjun, Tanmoy Chakraborty
Taxonomies are hierarchical knowledge graphs crucial for recommendation systems, and web applications. As data grows, expanding taxonomies is essential, but existing methods face k…
