ACL 20222022Pre-trained language models have been recently shown to benefit task-oriented dialogue (TOD) systems. Despite their success, existing methods often formulate this task as a cascaded generation problem which can lead to error accumulation across different sub-tasks and greater data annotation overhead. In this study, we present PPTOD, a unified plug-and-play model for task-oriented dialogue. In addition,

SDM 20222022Classification of large multivariate time series with strong class imbalance is an important task in real-world applications. Standard methods of class weights, oversampling, or parametric data augmentation do not always yield significant improvements for predicting minority classes of interest. Non-parametric data augmentation with Generative Adversarial Networks (GANs) offers a promising solution. We

ICASSP 20222022Acoustic event classification (AEC) is the task of determining whether certain events occur in an audio clip. Inspired by previous research [1, 2, 3] that embeddings from event labels can be leveraged to facilitate the learning of new detectors with no or limited audio samples, we introduce Wikipedia-based text embeddings as auxiliary information to improve AEC. We describe how to extract label embeddings

ICASSP 20222022Recognizing the intents and domains of users’ spoken and written language is a key component of Natural Language Understanding (NLU) systems. Real applications however encounter dynamic, rapidly evolving environments with newly emerging intents and domains, for which no labeled data or prior information is available. For such a setting, we propose a novel framework, ADVIN, to automatically discover novel

ICASSP 20222022Due to the variance of optical properties across different people, the performance of a person-agnostic gaze estimation model may not generalize well on a specific person. Though one may achieve better performance by training a person-specific model, it typically requires a large number of samples which is not available in real-life scenarios. Hence, few-shot gaze estimation method is preferred for the
