Towards Robust Aspect-based Sentiment Analysis through Non-counterfactual Augmentations

no code implementations24 Jun 2023 Xinyu Liu, Yan Ding, Kaikai An, Chunyang Xiao, Pranava Madhyastha, Tong Xiao, Jingbo Zhu

While state-of-the-art NLP models have demonstrated excellent performance for aspect based sentiment analysis (ABSA), substantial evidence has been presented on their lack of robustness.

A call for better unit testing for invariant risk minimisation

1 code implementation6 Jun 2021 Chunyang Xiao, Pranava Madhyastha

In this paper we present a controlled study on the linearized IRM framework (IRMv1) introduced in Arjovsky et al. (2020).

Grammatical Sequence Prediction for Real-Time Neural Semantic Parsing

no code implementations WS 2019 Chunyang Xiao, Christoph Teichmann, Konstantine Arkoudas

While sequence-to-sequence (seq2seq) models achieve state-of-the-art performance in many natural language processing tasks, they can be too slow for real-time applications.

Log-Linear RNNs: Towards Recurrent Neural Networks with Flexible Prior Knowledge

no code implementations8 Jul 2016 Marc Dymetman, Chunyang Xiao

We introduce LL-RNNs (Log-Linear RNNs), an extension of Recurrent Neural Networks that replaces the softmax output layer by a log-linear output layer, of which the softmax is a special case.

Move from Perturbed scheme to exponential weighting average

no code implementations22 Dec 2015 Chunyang Xiao

In an online decision problem, one makes decisions often with a pool of decision sequence called experts but without knowledge of the future.
