Calibration-Preserving Pruning: Compression as a Reliability Contract

Ibne Farabi Shihab, Adria Binte Habib, Anuj Sharma

Split conformal prediction, not the pruning rule, supplies finite-sample marginal coverage once a pruned model is fixed independently of the conformal calibration split. We study t…

CODS: Iterative Bellman-Residual Data Selection for Reusable Offline Reinforcement Learning

Ibne Farabi Shihab, Sanjeda Akter, Abu Sa-Adat Mohamed Moon-Im Al Ahsan +2

Offline reinforcement learning repeatedly trains policies from a fixed transition pool, making redundant data costly across seeds and hyperparameters, while naive subsampling can r…

Discrepancy-Rounded Fair Bandits with Static and Time-Varying Exposure Floors

Ibne Farabi Shihab, Joyanta Jyoti Mondal, Anuj Sharma

Minimum-exposure constraints arise in recommendation, content curation, and regulated allocation when each provider, arm, or group must receive guaranteed exposure inside a period…

Graph Dimensionality Reduction for Contextual Bandits: Structure-Specific Regret Bounds under Approximate Smoothness and Noisy Eigenspaces

Joyanta Jyoti Mondal, Ibne Farabi Shihab, Anuj Sharma

Contextual bandits with graph-structured arms arise in recommendation, citation retrieval, and social advertising, where arms connected on a graph tend to share reward signal. Stan…

Coverage-Based Calibration for Post-Training Quantization via Weighted Set Cover over Outlier Channels

Ibne Farabi Shihab, Sanjeda Akter, Anuj Sharma

Post-Training Quantization (PTQ) compresses large language models to low bit-widths using a small calibration set, and its quality depends strongly on which samples are chosen. We…

Continual Calibration: Coverage Can Collapse Before Accuracy in Lifelong LLM Fine-Tuning

Ibne Farabi Shihab, Sanjeda Akter, Anuj Sharma

Continual learning for large language models is typically evaluated through accuracy retention under sequential fine-tuning. We argue that this perspective is incomplete, because u…
