Waffling around for Performance: Visual Classification with Random Words and Broad Concepts

1 code implementation ICCV 2023 Karsten Roth, Jae Myung Kim, A. Sophia Koepke, Oriol Vinyals, Cordelia Schmid, Zeynep Akata

The visual classification performance of vision-language models such as CLIP has been shown to benefit from additional semantic knowledge from large language models (LLMs) such as GPT-3.

Exposing and Mitigating Spurious Correlations for Cross-Modal Retrieval

no code implementations6 Apr 2023 Jae Myung Kim, A. Sophia Koepke, Cordelia Schmid, Zeynep Akata

In this work, we introduce ODmAP@k, an object decorrelation metric that measures a model's robustness to spurious correlations in the training data.

Bridging the Gap between Model Explanations in Partially Annotated Multi-label Classification

2 code implementations CVPR 2023 Youngwook Kim, Jae Myung Kim, Jieun Jeong, Cordelia Schmid, Zeynep Akata, Jungwoo Lee

Based on these findings, we propose to boost the attribution scores of the model trained with partial labels to make its explanation resemble that of the model trained with full labels.

Likelihood Annealing: Fast Calibrated Uncertainty for Regression

no code implementations21 Feb 2023 Uddeshya Upadhyay, Jae Myung Kim, Cordelia Schmidt, Bernhard Schölkopf, Zeynep Akata

Recent advances in deep learning have shown that uncertainty estimation is becoming increasingly important in applications such as medical imaging, natural language processing, and autonomous systems.

Large Loss Matters in Weakly Supervised Multi-Label Classification

1 code implementation CVPR 2022 Youngwook Kim, Jae Myung Kim, Zeynep Akata, Jungwoo Lee

In this work, we first regard unobserved labels as negative labels, casting the WSML task into noisy multi-label classification.

Variational Perturbations for Visual Feature Attribution

no code implementations29 Sep 2021 Jae Myung Kim, Eunji Kim, Sungroh Yoon, Jungwoo Lee, Cordelia Schmid, Zeynep Akata

Explaining a complex black-box system in a post-hoc manner is important to understand its predictions.

Beyond Examples: Constructing Explanation Space for Explaining Prototypes

no code implementations29 Sep 2021 Hyungjun Joo, Seokhyeon Ha, Jae Myung Kim, Sungyeob Han, Jungwoo Lee

As deep learning has been successfully deployed in diverse applications, there is ever increasing need for explaining its decision.

Keep CALM and Improve Visual Feature Attribution

1 code implementation ICCV 2021 Jae Myung Kim, Junsuk Choe, Zeynep Akata, Seong Joon Oh

The class activation mapping, or CAM, has been the cornerstone of feature attribution methods for multiple vision tasks.

Variational saliency maps for explaining model's behavior

no code implementations1 Jan 2021 Jae Myung Kim, Eunji Kim, Seokhyeon Ha, Sungroh Yoon, Jungwoo Lee

Saliency maps have been widely used to explain the behavior of an image classifier.

REST: Performance Improvement of a Black Box Model via RL-based Spatial Transformation

no code implementations16 Feb 2020 Jae Myung Kim, Hyungjin Kim, Chanwoo Park, Jungwoo Lee

Our work aims to improve the robustness by adding a REST module in front of any black boxes and training only the REST module without retraining the original black box model in an end-to-end manner, i. e. we try to convert the real-world data into training distribution which the performance of the black-box model is best suited for.

Exploring linearity of deep neural network trained QSM: QSMnet+

1 code implementation17 Sep 2019 Woojin Jung, Jaeyeon Yoon, Joon Yul Choi, Jae Myung Kim, Yoonho Nam, Eung Yeop Kim, Jong-Ho Lee

To overcome this limitation, a data augmentation method is proposed to generalize the network for a wider range of susceptibility.

Sampling-based Bayesian Inference with gradient uncertainty

no code implementations8 Dec 2018 Chanwoo Park, Jae Myung Kim, Seok Hyeon Ha, Jungwoo Lee

In this paper, we show that predictive uncertainty can be efficiently estimated when we incorporate the concept of gradients uncertainty into posterior sampling.
