Combining Domain and Alignment Vectors Provides Better Knowledge-Safety Trade-offs in LLMs

ACL 2025short

There is a growing interest in training domain-expert LLMs that excel in specific technical fields compared to their general-purpose instruction-tuned counterparts. However, these expert models are not either explicitly trained to be safe, or experience a loss in their safety abilities in the proces…

Small Encoders Can Rival Large Decoders in Detecting Groundedness

ACL 2025finding

Augmenting large language models (LLMs) with external context significantly improves their performance in natural language processing (NLP) tasks. However, LLMs struggle to answer queries reliably when the provided context lacks information, often resorting to ungrounded speculation or internal know…

A Deep Dive into the Trade-Offs of Parameter-Efficient Preference Alignment Techniques

ACL 2024long

Large language models are first pre-trained on trillions of tokens and then instruction-tuned or aligned to specific preferences. While pre-training remains out of reach for most researchers due to the compute required, fine-tuning has become affordable thanks to parameter-efficient methods such as…

Exploring Quantization for Efficient Pre-Training of Transformer Language Models

EMNLP 2024finding

The increasing scale of Transformer models has led to an increase in their pre-training computational requirements. While quantization has proven to be effective after pre-training and during fine-tuning, applying quantization in Transformers during pre-training has remained largely unexplored at sc…
