Alternate Preference Optimization for Unlearning Factual Knowledge in Large Language Models

COLING 2025main

Machine unlearning aims to efficiently eliminate the influence of specific training data, known as the forget set, from the model. However, existing unlearning methods for Large Language Models (LLMs) face a critical challenge: they rely solely on negative feedback to suppress responses related to t…

Does quantization affect models’ performance on long-context tasks?

EMNLP 2025

Large language models (LLMs) now support context windows exceeding 128K tokens, but this comes with significant memory requirements and high inference latency. Quantization can mitigate these costs, but may degrade performance. In this work, we present the first systematic evaluation of quantized LL

DITTO: Data-efficient and Fair Targeted Subset Selection for ASR Accent Adaptation

ACL 2023long

State-of-the-art Automatic Speech Recognition (ASR) systems are known to exhibit disparate performance on varying speech accents. To improve performance on a specific target accent, a commonly adopted solution is to finetune the ASR model using accent-specific labeled speech. However, acquiring larg…
