Appearance Debiased Gaze Estimation via Stochastic Subject-Wise Adversarial Learning

no code implementations25 Jan 2024 Suneung Kim, Woo-Jeoung Nam, Seong-Whan Lee

In this paper, we address these challenges and propose a novel framework: Stochastic subject-wise Adversarial gaZE learning (SAZE), which trains a network to generalize the appearance of subjects.

Interpreting Deep Neural Networks with Relative Sectional Propagation by Analyzing Comparative Gradients and Hostile Activations

no code implementations7 Dec 2020 Woo-Jeoung Nam, Jaesik Choi, Seong-Whan Lee

As a result, it is possible to assign the bi-polar relevance scores of the target (positive) and hostile (negative) attributions while maintaining each attribution aligned with the importance.

Rotation Invariant Aerial Image Retrieval with Group Convolutional Metric Learning

no code implementations19 Oct 2020 Hyunseung Chung, Woo-Jeoung Nam, Seong-Whan Lee

In this work, we introduce a novel method for retrieving aerial images by merging group convolution with attention mechanism and metric learning, resulting in robustness to rotational variations.
