Copula Based Trainable Calibration Error Estimator of Multi-Label Classification with Label Interdependencies

AISTATS 2025poster

A key challenge in calibrating Multi-Label Classification(MLC) problems is to consider the interdependencies among labels. To address this, in this research we propose an unbiased, differentiable, trainable calibration error estimator for MLC problems by using Copula. Unlike other methods for calibr…

Label Dependency Aware Loss for Reliable Multi-Label Medical Image Classification

ICASSP 2025accepted

A key challenge in multi-label classification is to model the dependencies between the labels while ensuring proper calibration, as the assumption of label independence often results in inferior classification performance and poor calibration. However, most of the earlier works that modeled label de…

sudoLLM: On Multi-role Alignment of Language Models

EMNLP 2025

User authorization-based access privileges are a key feature in many safety-critical systems, but have not been extensively studied in the large language model (LLM) realm. In this work, drawing inspiration from such access control systems, we introduce sudoLLM, a novel framework that results in mul
