SABAF: Removing Strong Attribute Bias from Neural Networks with Adversarial Filtering

1 code implementation13 Nov 2023 Jiazhi Li, Mahyar Khayatkhoei, Jiageng Zhu, Hanchen Xie, Mohamed E. Hussein, Wael AbdAlmageed

To that end, in this work, we mathematically and empirically reveal the limitation of existing attribute bias removal methods in presence of strong bias and propose a new method that can mitigate this limitation.

Information-Theoretic Bounds on The Removal of Attribute-Specific Bias From Neural Networks

1 code implementation8 Oct 2023 Jiazhi Li, Mahyar Khayatkhoei, Jiageng Zhu, Hanchen Xie, Mohamed E. Hussein, Wael AbdAlmageed

Ensuring a neural network is not relying on protected attributes (e. g., race, sex, age) for predictions is crucial in advancing fair and trustworthy AI.

A Critical View of Vision-Based Long-Term Dynamics Prediction Under Environment Misalignment

1 code implementation12 May 2023 Hanchen Xie, Jiageng Zhu, Mahyar Khayatkhoei, Jiazhi Li, Mohamed E. Hussein, Wael AbdAlmageed

In this paper, we investigate two challenging conditions for environment misalignment: Cross-Domain and Cross-Context by proposing four datasets that are designed for these challenges: SimB-Border, SimB-Split, BlenB-Border, and BlenB-Split.

SW-VAE: Weakly Supervised Learn Disentangled Representation Via Latent Factor Swapping

no code implementations21 Sep 2022 Jiageng Zhu, Hanchen Xie, Wael Abd-Almageed

However, the training process without utilizing any supervision signal have been proved to be inadequate for disentanglement representation learning.

Partner-Assisted Learning for Few-Shot Image Classification

no code implementations ICCV 2021 Jiawei Ma, Hanchen Xie, Guangxing Han, Shih-Fu Chang, Aram Galstyan, Wael Abd-Almageed

In this paper, we focus on the design of training strategy to obtain an elemental representation such that the prototype of each novel class can be estimated from a few labeled samples.

MUSCLE: Strengthening Semi-Supervised Learning Via Concurrent Unsupervised Learning Using Mutual Information Maximization

no code implementations30 Nov 2020 Hanchen Xie, Mohamed E. Hussein, Aram Galstyan, Wael Abd-Almageed

We also show that MUSCLE has the potential to boost the classification performance when used in the fine-tuning phase for a model pre-trained only on unlabeled data.
