Asymmetric feature interaction for interpreting model predictions

1 code implementation12 May 2023 Xiaolei Lu, Jianghong Ma, Haode Zhang

In this work, we propose an asymmetric feature interaction attribution explanation model that aims to explore asymmetric higher-order feature interactions in the inference of deep neural NLP models.

Learning Ambiguity from Crowd Sequential Annotations

no code implementations4 Jan 2023 Xiaolei Lu

Most crowdsourcing learning methods treat disagreement between annotators as noisy labelings while inter-disagreement among experts is often a good indicator for the ambiguity and uncertainty that is inherent in natural language.

Modeling sequential annotations for sequence labeling with crowds

no code implementations20 Sep 2022 Xiaolei Lu, Tommy W. S. Chow

To accelerate the marginalization of the proposed model, a valid label sequence inference (VLSE) method is proposed to derive the valid ground-truth label sequences from crowd sequential annotations.

Weak Disambiguation for Partial Structured Output Learning

no code implementations20 Sep 2022 Xiaolei Lu, Tommy W. S. Chow

Existing disambiguation strategies for partial structured output learning just cannot generalize well to solve the problem that there are some candidates which can be false positive or similar to the ground-truth label.

Partial sequence labeling with structured Gaussian Processes

no code implementations20 Sep 2022 Xiaolei Lu, Tommy W. S. Chow

Then confidence measure is introduced in the model to address different contributions of candidate labels, which enables the ground-truth label information to be utilized in parameter learning.
