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.

On the Convergence of Nonconvex Continual Learning with Adaptive Learning Rate

no code implementations29 Sep 2021 Sungyeob Han, Yeongmo Kim, Jungwoo Lee

The memory based continual learning stores a small subset of the data for previous tasks and applies various methods such as quadratic programming and sample selection.

Nonconvex Continual Learning with Episodic Memory

no code implementations1 Jan 2021 Sungyeob Han, Yeongmo Kim, Jungwoo Lee

We also show that memory-based approaches have an inherent problem of overfitting to memory, which degrades the performance on previously learned tasks, namely catastrophic forgetting.

Adversarial training with perturbation generator networks

no code implementations25 Sep 2019 Hyeungill Lee, Sungyeob Han, Jungwoo Lee

However, these adversarial attack methods used in these techniques are fixed, making the model stronger only to attacks used in training, which is widely known as an overfitting problem.

Generative Adversarial Trainer: Defense to Adversarial Perturbations with GAN

no code implementations9 May 2017 Hyeungill Lee, Sungyeob Han, Jungwoo Lee

The generator network generates an adversarial perturbation that can easily fool the classifier network by using a gradient of each image.
