ThinkRetrieve: Retrieval-Augmented Reasoning Traces for Test-Time Scaling

Vaibhav Singh, Soumya Suvra Ghosal, Sarvesh Gharat +3

Large Reasoning Models (LRMs) improve performance by allocating additional inference-time compute to generate extended chain-of-thought reasoning. However, recent studies reveal th…

KITE: Kernelized and Information Theoretic Exemplars for In-Context Learning

Vaibhav Singh, Soumya Suvra Ghosal, Kapu Nirmal Joshua +2

In-context learning (ICL) has emerged as a powerful paradigm for adapting large language models (LLMs) to new and data-scarce tasks using only a few carefully selected task-specifi…

Enhancing Deep Neural Network Reliability with Refinement and Calibration

Ramya Hebbalaguppe, Ajay Shastry, Soumya Suvra Ghosal +1

Although deep neural networks (DNNs) achieve high predictive accuracy, their confidence estimates are often unreliable, potentially compromising user trust in their decisions. This…

VisRef: Visual Refocusing while Thinking Improves Test-Time Scaling in Multi-Modal Large Reasoning Models

Soumya Suvra Ghosal, Youngeun Kim, Zhuowei Li +6

Advances in large reasoning models have shown strong performance on complex reasoning tasks by scaling test-time compute through extended reasoning. However, recent studies observe…

Safety Recovery in Reasoning Models Is Only a Few Early Steering Steps Away

Soumya Suvra Ghosal, Souradip Chakraborty, Vaibhav Singh +3

Reinforcement learning (RL) based post-training for explicit chain-of-thought (e.g., GRPO) improves the reasoning ability of multimodal large-scale reasoning models (MLRMs). But re…

Does Thinking More always Help? Mirage of Test-Time Scaling in Reasoning Models

Soumya Suvra Ghosal, Souradip Chakraborty, Avinash Reddy +6

Recent trends in test-time scaling for reasoning models (e.g., OpenAI o1, DeepSeek R1) have led to a popular belief that extending thinking traces using prompts like "Wait" or "Let…
