Few Shot Part Segmentation Reveals Compositional Logic for Industrial Anomaly Detection

no code implementations21 Dec 2023 Soopil Kim, Sion An, Philip Chikontwe, Myeongkyun Kang, Ehsan Adeli, Kilian M. Pohl, Sang Hyun Park

In this study, we introduce a novel component segmentation model for LA detection that leverages a few labeled samples and unlabeled images sharing logical constraints.

Feature Re-calibration based Multiple Instance Learning for Whole Slide Image Classification

1 code implementation22 Jun 2022 Philip Chikontwe, Soo Jeong Nam, Heounjeong Go, Meejeong Kim, Hyun Jung Sung, Sang Hyun Park

Whole slide image (WSI) classification is a fundamental task for the diagnosis and treatment of diseases; but, curation of accurate labels is time-consuming and limits the application of fully-supervised methods.

CAD: Co-Adapting Discriminative Features for Improved Few-Shot Classification

no code implementations CVPR 2022 Philip Chikontwe, Soopil Kim, Sang Hyun Park

Few-shot classification is a challenging problem that aims to learn a model that can adapt to unseen classes given a few labeled samples.

Uncertainty-Aware Semi-Supervised Few Shot Segmentation

no code implementations18 Oct 2021 Soopil Kim, Philip Chikontwe, Sang Hyun Park

During inference, query segmentation is predicted using prototypes from both support and unlabeled images including low-level features of the query images.

Self-Supervised Learning based CT Denoising using Pseudo-CT Image Pairs

no code implementations6 Apr 2021 Dongkyu Won, Euijin Jung, Sion An, Philip Chikontwe, Sang Hyun Park

The proposed ensemble noise model can generate realistic CT noise, and thus our method significantly improves the denoising performance existing denoising models trained by supervised- and self-supervised learning.

Multiple Instance Learning with Center Embeddings for Histopathology Classification

1 code implementation29 Sep 2020 Philip Chikontwe, Meejeong Kim, Soo Jeong Nam, Heounjeong Go, Sang Hyun Park

To address this, recent methods have considered WSI classification as a Multiple Instance Learning (MIL) problem often with a multi-stage process for learning instance and slide level features.

Few-Shot Relation Learning with Attention for EEG-based Motor Imagery Classification

no code implementations3 Mar 2020 Sion An, Soopil Kim, Philip Chikontwe, Sang Hyun Park

In addition to the unified learning of feature similarity and a few shot classifier, our method leads to emphasize informative features in support data relevant to the query data, which generalizes better on unseen subjects.
