Translation Deserves Better: Analyzing Translation Artifacts in Cross-lingual Visual Question Answering

ACL 2024findings

Building a reliable visual question answering (VQA) system across different languages is a challenging problem, primarily due to the lack of abundant samples for training. To address this challenge, recent studies have employed machine translation systems for the cross-lingual VQA task. This involve…

On the Importance of Feature Decorrelation for Unsupervised Representation Learning in Reinforcement Learning

ICML 2023poster

Recently, unsupervised representation learning (URL) has improved the sample efficiency of Reinforcement Learning (RL) by pretraining a model from a large unlabeled dataset. The underlying principle of these methods is to learn temporally predictive representations by predicting future states in the…

Towards Accurate Translation via Semantically Appropriate Application of Lexical Constraints

ACL 2023findings

Lexically-constrained NMT (LNMT) aims to incorporate user-provided terminology into translations. Despite its practical advantages, existing work has not evaluated LNMT models under challenging real-world conditions. In this paper, we focus on two important but understudied issues that lie in the cu…
