Measuring and curing reasoning rigidity: from decorative chain-of-thought to genuine faithfulness
Abhinaba Basu, Pavan Chakraborty
Language models increasingly show their work by writing step-by-step reasoning before answering. But are these steps genuinely used, or is the answer rigid - fixed before reasoning…
When Names Change Verdicts: Intervention Consistency Reveals Systematic Bias in LLM Decision-Making
Abhinaba Basu, Pavan Chakraborty
Large language models (LLMs) are increasingly used for high-stakes decisions, yet their susceptibility to spurious features remains poorly characterized. We introduce ICE-Guard, a…
Proof-Carrying Materials: Falsifiable Safety Certificates for Machine-Learned Interatomic Potentials
Abhinaba Basu, Pavan Chakraborty
Machine-learned interatomic potentials (MLIPs) are deployed for high-throughput materials screening without formal reliability guarantees. We show that a single MLIP used as a stab…
Budget-Sensitive Discovery Scoring: A Formally Verified Framework for Evaluating AI-Guided Scientific Selection
Abhinaba Basu, Pavan Chakraborty
Scientific discovery increasingly relies on AI systems to select candidates for expensive experimental validation, yet no principled, budget-aware evaluation framework exists for c…
ICE: Intervention-Consistent Explanation Evaluation with Statistical Grounding for LLMs
Abhinaba Basu, Pavan Chakraborty
Evaluating whether explanations faithfully reflect a model's reasoning remains an open problem. Existing benchmarks use single interventions without statistical testing, making it…
Contextual StereoSet: Stress-Testing Bias Alignment Robustness in Large Language Models
Abhinaba Basu, Pavan Chakraborty
A model that avoids stereotypes in a lab benchmark may not avoid them in deployment. We show that measured bias shifts dramatically when prompts mention different places, times, or…
Polyp detection in colonoscopy images using YOLOv11
Alok Ranjan Sahoo, Satya Sangram Sahoo, Pavan Chakraborty
Colorectal cancer (CRC) is one of the most commonly diagnosed cancers all over the world. It starts as a polyp in the inner lining of the colon. To prevent CRC, early polyp detecti…
Point-GR: Graph Residual Point Cloud Network for 3D Object Classification and Segmentation
Md Meraz, Md Afzal Ansari, Mohammed Javed +1
In recent years, the challenge of 3D shape analysis within point cloud data has gathered significant attention in computer vision. Addressing the complexities of effective 3D infor…
Inverse kinematics learning of a continuum manipulator using limited real time data
Alok Ranjan Sahoo, Pavan Chakraborty
Data driven control of a continuum manipulator requires a lot of data for training but generating sufficient amount of real time data is not cost efficient. Random actuation of the…
Hybrid CNN Bi-LSTM neural network for Hyperspectral image classification
Alok Ranjan Sahoo, Pavan Chakraborty
Hyper spectral images have drawn the attention of the researchers for its complexity to classify. It has nonlinear relation between the materials and the spectral information provi…
Guidance system for Visually Impaired Persons using Deep Learning and Optical flow
Shwetang Dubey, Alok Ranjan Sahoo, Pavan Chakraborty
Visually impaired persons find it difficult to know about their surroundings while walking on a road. Walking sticks used by them can only give them information about the obstacles…
