Scale Equalization for Multi-Level Feature Fusion

no code implementations2 Feb 2024 Bum Jun Kim, Sang Woo Kim

We discover that scale disequilibrium is caused by bilinear upsampling, which is supported by both theoretical and empirical evidence.

Decoder Semantic Segmentation

Analysis of NaN Divergence in Training Monocular Depth Estimation Model

no code implementations7 Nov 2023 Bum Jun Kim, Hyeonah Jang, Sang Woo Kim

The latest advances in deep learning have facilitated the development of highly accurate monocular depth estimation models.

Resolution-Aware Design of Atrous Rates for Semantic Segmentation Networks

no code implementations26 Jul 2023 Bum Jun Kim, Hyeyeon Choi, Hyeonah Jang, Sang Woo Kim

However, fixed values of atrous rates are used for the ASPP module, which restricts the size of its field of view.

Understanding Gaussian Attention Bias of Vision Transformers Using Effective Receptive Fields

1 code implementation8 May 2023 Bum Jun Kim, Hyeyeon Choi, Hyeonah Jang, Sang Woo Kim

Based on this observation, we propose explicitly adding a Gaussian attention bias that guides the positional embedding to have the corresponding pattern from the beginning of training.

On the Ideal Number of Groups for Isometric Gradient Propagation

no code implementations7 Feb 2023 Bum Jun Kim, Hyeyeon Choi, Hyeonah Jang, Sang Woo Kim

First, we find that the number of groups influences the gradient behavior of the group normalization layer.
