The Documentation and Traceability Burden of the Indian EV Transition
Dawar Jyoti Deka, Nilesh Sarkar
The electric vehicle transition in India is usually told through batteries, cost and charging. Less visibly, it is a story about documentation. Electrification layers a new and fas…
Compliance Evidence in the Automotive Supply Chain: A Systematisation of the Quality-Document Spine and a Taxonomy of Documentation Failure Modes
Dawar Jyoti Deka, Nilesh Sarkar
The automotive industry runs on a dense, standardised chain of supplier-quality and certification evidence: production part approval packages, initial sample reports, material cert…
Causal Dimensionality of Transformer Representations: Measurement, Scaling, and Layer Structure
Nilesh Sarkar, Dawar Jyoti Deka
Sparse autoencoders (SAEs) decompose transformer residual streams into interpretable feature dictionaries, yet the relationship between SAE width and causal influence on model outp…
Prompt Sensitivity in Vision-Language Grounding: How Small Changes in Wording Affect Object Detection
Dawar Jyoti Deka, Amit Sethi, Syed Mohammad Ali
Vision-language models enable open-vocabulary object grounding through natural language queries, under the implicit assumption that semantically equivalent descriptions yield consi…
Inference-Time Temporal Probability Smoothing for Stable Video Segmentation with SAM2 under Weak Prompts
Dawar Jyoti Deka
Interactive video segmentation models such as SAM2 have demonstrated strong generalization across diverse visual domains. However, under weak user supervision, for example, when sp…
Geometric Limits of Knowledge Distillation: A Minimum-Width Theorem via Superposition Theory
Nilesh Sarkar, Dawar Jyoti Deka
Knowledge distillation compresses large teachers into smaller students, but performance saturates at a loss floor that persists across training methods and objectives. We argue thi…
