A Survey on Natural Language Counterfactual Generation

EMNLP 2024finding

Natural language counterfactual generation aims to minimally modify a given text such that the modified text will be classified into a different class. The generated counterfactuals provide insight into the reasoning behind a model’s predictions by highlighting which words significantly influence th…

Dual-View Whitening on Pre-trained Text Embeddings for Sequential Recommendation

AAAI 2024technical

Recent advances in sequential recommendation models have demonstrated the efficacy of integrating pre-trained text embeddings with item ID embeddings to achieve superior performance. However, our study takes a unique perspective by exclusively focusing on the untapped potential of text embeddings, o…

PairCFR: Enhancing Model Training on Paired Counterfactually Augmented Data through Contrastive Learning

ACL 2024long

Counterfactually Augmented Data (CAD) involves creating new data samples by applying minimal yet sufficient modifications to flip the label of existing data samples to other classes. Training with CAD enhances model robustness against spurious features that happen to correlate with labels by spreadi…

RevMUX: Data Multiplexing with Reversible Adapters for Efficient LLM Batch Inference

EMNLP 2024main

Large language models (LLMs) have brought a great breakthrough to the natural language processing (NLP) community, while leading the challenge of handling concurrent customer queries due to their high throughput demands. Data multiplexing addresses this by merging multiple inputs into a single compo…

Efficient Cross-Task Prompt Tuning for Few-Shot Conversational Emotion Recognition

EMNLP 2023long findings

Emotion Recognition in Conversation (ERC) has been widely studied due to its importance in developing emotion-aware empathetic machines. The rise of pre-trained language models (PLMs) has further pushed the limit of ERC performance. However, most recent works on ERC using PLMs are heavily data-drive…

History-Aware Hierarchical Transformer for Multi-session Open-domain Dialogue System

EMNLP 2022finding

With the evolution of pre-trained language models, current open-domain dialogue systems have achieved great progress in conducting one-session conversations. In contrast, Multi-Session Conversation (MSC), which consists of multiple sessions over a long term with the same user, is under-investigated.…
