Learning Discriminative Representations and Decision Boundaries for Open Intent Detection

نویسندگان

چکیده

Open intent detection is a significant problem in natural language understanding, which aims to identify the unseen open while ensuring known identification performance. However, current methods face two major challenges. Firstly, they struggle learn friendly representations detect with prior knowledge of only intents. Secondly, there lack an effective approach obtaining specific and compact decision boundaries for To address these issues, this paper presents original framework called DA-ADB, successively learns distance-aware adaptive detection. Specifically, we first leverage distance information enhance distinguishing capability representations. Then, design novel loss function obtain appropriate by balancing both empirical space risks. Extensive experiments demonstrate effectiveness proposed boundary learning strategies. Compared state-of-the-art methods, our achieves substantial improvements on three benchmark datasets. Furthermore, it yields robust performance varying proportions labeled data categories. The full codes are available use at https://github.com/thuiar/TEXTOIR .

Discriminative learning for neural decision feedback equalizers

In this work new Decision-Feedback (DF) Neural Equalizers (DFNE) are introduced and compared with classical DF equalizers and Viterbi demodulators. It is shown that the choice of an innovative cost functional based on the Discriminative Learning (DL) technique, coupled with a fast training paradigm, can provide neural equalizers that outperform standard DF equalizers (DFEs) at practical signal ...

Discriminative Learning over Constrained Latent Representations

This paper proposes a general learning framework for a class of problems that require learning over latent intermediate representations. Many natural language processing (NLP) decision problems are defined over an expressive intermediate representation that is not explicit in the input, leaving the algorithm with both the task of recovering a good intermediate representation and learning to cla...

Learning Discriminative Representations for Semantic Cross Media Retrieval

Heterogeneous gap among different modalities emerges as one of the critical issues in modern AI problems. Unlike traditional uni-modal cases, where raw features are extracted and directly measured, the heterogeneous nature of cross modal tasks requires the intrinsic semantic representation to be compared in a unified framework. This paper studies the learning of different representations that c...

Learning Discriminative Distance Functions for Case Retrieval and Decision Support

The importance of learning distance functions is gradually being acknowledged by the machine learning community, and different techniques are suggested that can successfully learn a strong distance function in many various contexts. Nevertheless the studies in the area are still rather fragmentary; they lack systematic analysis and focus on a limited circle of application domains. In this paper...
