A survey of joint intent detection and slot filling models in natural language understanding

H Weld, X Huang, S Long, J Poon, SC Han - ACM Computing Surveys, 2022 - dl.acm.org
Intent classification, to identify the speaker's intention, and slot filling, to label each token
with a semantic type, are critical tasks in natural language understanding. Traditionally the …

Contrastive out-of-distribution detection for pretrained transformers

W Zhou, F Liu, M Chen - arXiv preprint arXiv:2104.08812, 2021 - arxiv.org
Pretrained Transformers achieve remarkable performance when training and test data are
from the same distribution. However, in real-world scenarios, the model often faces out-of …

Deep open intent classification with adaptive decision boundary

H Zhang, H Xu, TE Lin - Proceedings of the AAAI Conference on …, 2021 - ojs.aaai.org
Open intent classification is a challenging task in dialogue systems. On the one hand, it
should ensure the quality of known intent identification. On the other hand, it needs to detect …

Deep unknown intent detection with margin loss

TE Lin, H Xu - arXiv preprint arXiv:1906.00434, 2019 - arxiv.org
Identifying the unknown (novel) user intents that have never appeared in the training set is a
challenging task in the dialogue system. In this paper, we present a two-stage method for …

Out-of-domain detection for natural language understanding in dialog systems

Y Zheng, G Chen, M Huang - IEEE/ACM Transactions on Audio …, 2020 - ieeexplore.ieee.org
Natural Language Understanding (NLU) is a vital component of dialogue systems, and its

Modeling discriminative representations for out-of-domain detection with supervised contrastive learning

Z Zeng, K He, Y Yan, Z Liu, Y Wu, H Xu, H Jiang… - arXiv preprint arXiv …, 2021 - arxiv.org
Detecting Out-of-Domain (OOD) or unknown intents from user queries is essential in a task-
oriented dialog system. A key challenge of OOD detection is to learn discriminative semantic …

A deep generative distance-based classifier for out-of-domain detection with mahalanobis space

H Xu, K He, Y Yan, S Liu, Z Liu… - Proceedings of the 28th …, 2020 - aclanthology.org
Detecting out-of-domain (OOD) input intents is critical in the task-oriented dialog system.

Out-of-domain detection for low-resource text classification tasks

M Tan, Y Yu, H Wang, D Wang, S Potdar… - arXiv preprint arXiv …, 2019 - arxiv.org
Out-of-domain (OOD) detection for low-resource text classification is a realistic but
understudied task. The goal is to detect the OOD cases with limited in-domain (ID) training …

Benchmarking out-of-distribution detection in visual question answering

X Shi, S Lee - Proceedings of the IEEE/CVF Winter …, 2024 - openaccess.thecvf.com
When faced with an out-of-distribution (OOD) question or image, visual question answering
(VQA) systems may provide unreliable answers. If relied on by real users or secondary …
