ICLR 20232023This work studies the threats of adversarial attack on multivariate probabilistic forecasting models and viable defense mechanisms. Our studies discover a new attack pattern that negatively impact the forecasting of a target time series via making strategic, sparse (imperceptible) modifications to the past observations of a small number of other time series. To mitigate the impact of such attack, we have

ICLR 2023 Workshop on Deep Learning for Code (DL4C)2023Code understanding and generation require learning the mapping between human and programming languages. As human and programming languages are different in vocabulary, semantic, and, syntax, it is challenging for an autoregressive model to generate a sequence of tokens that is both semantically (i.e., carry the right meaning) and syntactically correct (i.e., in the right sequence order). Inspired by this

Web Conference 2023 Workshop on Natural-Language Processing for Social Media2023Language model pre-training has led to state-of-the-art performance in text summarization. While a variety of pre-trained transformer models are available nowadays, they are mostly trained on documents. In this study we introduce self-supervised pre-training to enhance the BERT model’s semantic and structural understanding of dialog texts from social media. We also propose a semisupervised teacher-student

ICASSP 20232023This work focuses on modelling a speaker’s accent that does not have a dedicated text-to-speech (TTS) frontend, includ-ing a grapheme-to-phoneme (G2P) module. Prior work on modelling accents assumes a phonetic transcription is avail-able for the target accent, which might not be the case for low-resource, regional accents. In our work, we propose an approach whereby we first augment the target accent data

ECIR 20232023AI assistants are gradually becoming embedded in our lives, utilized for everyday tasks like shopping or music. In addition to the everyday utilization of AI assistants, many users engage them with playful shopping requests, gauging their ability to understand – or simply seeking amusement. However, these requests are often not being responded to in the same playful manner, causing dissatisfaction and even
