Improving Performance of Semi-Supervised Learning by Adversarial Attacks

no code implementations8 Aug 2023 Dongyoon Yang, Kunwoong Kim, Yongdai Kim

Semi-supervised learning (SSL) algorithm is a setup built upon a realistic assumption that access to a large amount of labeled data is tough.

ODIM: an efficient method to detect outliers via inlier-memorization effect of deep generative models

no code implementations11 Jan 2023 Dongha Kim, Jaesung Hwang, Jongjin Lee, Kunwoong Kim, Yongdai Kim

This study aims to solve the unsupervised outlier detection problem where training data contain outliers, but any label information about inliers and outliers is not given.

SLIDE: a surrogate fairness constraint to ensure fairness consistency

1 code implementation7 Feb 2022 Kunwoong Kim, Ilsang Ohn, Sara Kim, Yongdai Kim

As they have a vital effect on social decision makings, AI algorithms should be not only accurate and but also fair.

Learning fair representation with a parametric integral probability metric

1 code implementation7 Feb 2022 Dongha Kim, Kunwoong Kim, Insung Kong, Ilsang Ohn, Yongdai Kim

That is, we derive theoretical relations between the fairness of representation and the fairness of the prediction model built on the top of the representation (i. e., using the representation as the input).

$L_q$ regularization for Fairness AI robust to sampling bias

no code implementations29 Sep 2021 Yongdai Kim, Sara Kim, Seonghyeon Kim, Kunwoong Kim

To ensure fairness on test data, we develop computationally efficient learning algorithms robust to sampling bias.

INN: A Method Identifying Clean-annotated Samples via Consistency Effect in Deep Neural Networks

no code implementations29 Jun 2021 Dongha Kim, Yongchan Choi, Kunwoong Kim, Yongdai Kim

By carrying out various experiments, we demonstrate that the INN method resolves the shortcomings in the memorization effect successfully and thus is helpful to construct more accurate deep prediction models with training data with noisy labels.
