WeCNLP 20212021Text-to-Text (T2T) denoising-pretraining-finetuning (DPF) paradigms (e.g. BERT, BART, GPT) have achieved great success in a wide range of encoding and decoding tasks in NLP. However, little has been explored on data-to-data (D2D) and data-to-text (D2T) tasks using DPF paradigms. This work fills in the gap by investigating D2D and T2T denoising-pretraining for D2T tasks. D2D and T2T DPF paradigms can leverage

EMNLP 2021 Workshop on the Fifth Widening NLP (WiNLP)2021Building supervised targeted sentiment analysis models for a new target domain requires substantial annotation effort since most datasets for this task are domain-specific. Domain adaptation for this task has two dimensions: the nature of targets and the opinion words used to describe sentiment towards the target. We present a data sampling strategy informed by domain differences across these two dimensions

ICNLSP 20212021A challenge for target-based sentiment analysis is that most datasets are domain-specific and thus building supervised models for a new target domain requires substantial annotation effort. Domain adaptation for this task has two dimensions: the nature of the targets (e.g., entity types, properties associated with entities, or arbitrary spans) and the opinion words used to describe the sentiment towards

NeurIPS 20212021Robustness of machine learning models is critical for security related applications, where real-world adversaries are uniquely focused on evading neural network based detectors. Prior work mainly focus on crafting adversarial examples (AEs) with small uniform norm-bounded perturbations across features to maintain the requirement of imperceptibility. However, uniform perturbations do not result in realistic

ACS Omega2021Graph neural networks (GNNs) constitute a class of deep learning methods for graph data. They have wide applications in chemistry and biology, such as molecular property prediction, reaction prediction, and drug−target interaction prediction. Despite the interest, GNN-based modeling is challenging as it requires graph data preprocessing and modeling in addition to programming and deep learning. Here, we
