Compact and De-biased Negative Instance Embedding for Multi-Instance Learning on Whole-Slide Image Classification

1 code implementation16 Feb 2024 Joohyung Lee, Heejeong Nam, Kwanhyung Lee, Sangchul Hahn

Using this free annotation, we introduce a semi-supervision signal to de-bias the inter-slide variability and to capture the common factors of variation within normal patches.

Self-Knowledge Distillation in Natural Language Processing

no code implementations RANLP 2019 Sangchul Hahn, Heeyoul Choi

Since deep learning became a key player in natural language processing (NLP), many deep learning models have been showing remarkable performances in a variety of NLP tasks, and in some cases, they are even outperforming humans.

Disentangling Latent Factors of Variational Auto-Encoder with Whitening

no code implementations8 Nov 2018 Sangchul Hahn, Heeyoul Choi

The proposed method is applied to the latent variables of variational auto-encoder (VAE), although it can be applied to any generative models with latent variables.

Gradient Acceleration in Activation Functions

no code implementations27 Sep 2018 Sangchul Hahn, Heeyoul Choi

Based on this explanation, we propose a new technique for activation functions, {\em gradient acceleration in activation function (GAAF)}, that accelerates gradients to flow even in the saturation area.

Understanding Dropout as an Optimization Trick
