NAACL 2021 Workshop on Multimodal Artificial Intelligence2021Explainable deep learning models are advantageous in many situations. Prior work mostly provide unimodal explanations through posthoc approaches not part of the original system design. Explanation mechanisms also ignore useful textual information present in images. In this paper, we propose MTXNet, an end-to-end trainable multimodal architecture to generate multimodal explanations, which focuses on the

NAACL 2021 Workshop on Privacy in Natural Language Processing2021Differentially-private mechanisms for text generation typically add carefully calibrated noise to input words and use the nearest neighbor to the noised input as the output word. When the noise is small in magnitude, these mechanisms are susceptible to reconstruction of the original sensitive text. This is because the nearest neighbor to the noised input is likely to be the original input. To mitigate this

NAACL 2021 TrustNLP Workshop on Trustworthy Natural Language Processing2021Ensuring strong theoretical privacy guarantees on text data is a challenging problem which is usually attained at the expense of utility. However, to improve the practicality of privacy preserving text analyses, it is essential to design algorithms that better optimize this tradeoff. To address this challenge, we propose a release mechanism that takes any (text) embedding vector as input and releases a

NAACL 2021 Workshop on Multimodal Artificial Intelligence2021Recent vision-language understanding approaches adopt a multi-modal transformer pretraining and finetuning paradigm. Prior work learns representations of text tokens and visual features with cross-attention mechanisms and captures the alignment solely based on indirect signals. In this work, we propose to enhance the alignment mechanism by incorporating image scene graph structures as the bridge between

It is better to verify: Semi-supervised learning with a human in the loop for large-scale NLU modelsNACCL 2021 Workshop on Data Science with Human-in-the-loop2021When a NLU model is updated, new utterances must be annotated to be included for training. However, manual annotation is very costly. We evaluate a semi-supervised learning workflow with a human in the loop in a production environment. The previous NLU model predicts the annotation of the new utterances, a human then reviews the predicted annotation. Only when the NLU prediction is assessed as incorrect
