Can You Really Trust Code Copilot? Evaluating Large Language Models from a Code Security Perspective

ACL 2025long

Code security and usability are both essential for various coding assistant applications driven by large language models (LLMs). Current code security benchmarks focus solely on single evaluation task and paradigm, such as code completion and generation, lacking comprehensive assessment across dimen…

Beyond the Known: Investigating LLMs Performance on Out-of-Domain Intent Detection

COLING 2024main

Out-of-domain (OOD) intent detection aims to examine whether the user’s query falls outside the predefined domain of the system, which is crucial for the proper functioning of task-oriented dialogue (TOD) systems. Previous methods address it by fine-tuning discriminative models. Recently, some studi…

SG-Bench: Evaluating LLM Safety Generalization Across Diverse Tasks and Prompt Types

NeurIPS 2024poster

Ensuring the safety of large language model (LLM) applications is essential for developing trustworthy artificial intelligence. Current LLM safety benchmarks have two limitations. First, they focus solely on either discriminative or generative evaluation paradigms while ignoring their interconnectio…

UEGP: Unified Expert-Guided Pre-training for Knowledge Rekindle

NAACL 2024findings

Pre-training and fine-tuning framework has become the standard training paradigm for NLP tasks and is also widely used in industrial-level applications. However, there are still a limitation with this paradigm: simply fine-tuning with task-specific objectives tends to converge to local minima, resul…

APP: Adaptive Prototypical Pseudo-Labeling for Few-shot OOD Detection

EMNLP 2023long findings

Detecting out-of-domain (OOD) intents from user queries is essential for a task-oriented dialogue system. Previous OOD detection studies generally work on the assumption that plenty of labeled IND intents exist. In this paper, we focus on a more practical few-shot OOD setting where there are only a…

Continual Generalized Intent Discovery: Marching Towards Dynamic and Open-world Intent Recognition

EMNLP 2023long findings

In a practical dialogue system, users may input out-of-domain (OOD) queries. The Generalized Intent Discovery (GID) task aims to discover OOD intents from OOD queries and extend them to the in-domain (IND) classifier. However, GID only considers one stage of OOD learning, and needs to utilize the da…

Decoupling Pseudo Label Disambiguation and Representation Learning for Generalized Intent Discovery

ACL 2023long

Generalized intent discovery aims to extend a closed-set in-domain intent classifier to an open-world intent set including in-domain and out-of-domain intents. The key challenges lie in pseudo label disambiguation and representation learning. Previous methods suffer from a coupling of pseudo label d…

Large Language Models Meet Open-World Intent Discovery and Recognition: An Evaluation of ChatGPT

EMNLP 2023long main

The tasks of out-of-domain (OOD) intent discovery and generalized intent discovery (GID) aim to extend a closed intent classifier to open-world intent sets, which is crucial to task-oriented dialogue (TOD) systems. Previous methods address them by fine-tuning discriminative models. Recently, althoug…

Disentangled Knowledge Transfer for OOD Intent Discovery with Unified Contrastive Learning

ACL 2022short

Discovering Out-of-Domain(OOD) intents is essential for developing new skills in a task-oriented dialogue system. The key challenge is how to transfer prior IND knowledge to OOD clustering. Different from existing work based on shared intent representation, we propose a novel disentangled knowledge…

Distribution Calibration for Out-of-Domain Detection with Bayesian Approximation

COLING 2022main

Out-of-Domain (OOD) detection is a key component in a task-oriented dialog system, which aims to identify whether a query falls outside the predefined supported intent set. Previous softmax-based detection algorithms are proved to be overconfident for OOD samples. In this paper, we analyze overconfi…

Exploiting domain-slot related keywords description for Few-Shot Cross-Domain Dialogue State Tracking

EMNLP 2022main

Collecting dialogue data with domain-slot-value labels for dialogue state tracking (DST) could be a costly process. In this paper, we propose a novel framework based on domain-slot related description to tackle the challenge of few-shot cross-domain DST. Specifically, we design an extraction module…

Generalized Intent Discovery: Learning from Open World Dialogue System

COLING 2022main

Traditional intent classification models are based on a pre-defined intent set and only recognize limited in-domain (IND) intent classes. But users may input out-of-domain (OOD) queries in a practical dialogue system. Such OOD queries can provide directions for future improvement. In this paper, we…

UniNL: Aligning Representation Learning with Scoring Function for OOD Detection via Unified Neighborhood Learning

EMNLP 2022main

Detecting out-of-domain (OOD) intents from user queries is essential for avoiding wrong operations in task-oriented dialogue systems. The key challenge is how to distinguish in-domain (IND) and OOD intents. Previous methods ignore the alignment between representation learning and scoring function, l…
