Learning to Solve Nonlinear Partial Differential Equation Systems To Accelerate MOSFET Simulation

no code implementations1 Jan 2021 Seungcheol Han, Jonghyun Choi, Sung-Min Hong

In order to accelerate the semiconductor device simulation, we propose to use a neural network to learn an approximate solution for desired boundary conditions.

Mitigating large adversarial perturbations on X-MAS (X minus Moving Averaged Samples)

1 code implementation19 Dec 2019 Woohyung Chun, Sung-Min Hong, Junho Huh, Inyup Kang

We propose the scheme that mitigates the adversarial perturbation $\epsilon$ on the adversarial example $X_{adv}$ ($=$ $X$ $\pm$ $\epsilon$, $X$ is a benign sample) by subtracting the estimated perturbation $\hat{\epsilon}$ from $X$ $+$ $\epsilon$ and adding $\hat{\epsilon}$ to $X$ $-$ $\epsilon$.

Controlling the privacy loss with the input feature maps of the layers in convolutional neural networks

no code implementations9 May 2018 Woohyung Chun, Sung-Min Hong, Junho Huh, Inyup Kang

We propose the method to sanitize the privacy of the IFM(Input Feature Map)s that are fed into the layers of CNN(Convolutional Neural Network)s. The method introduces the degree of the sanitization that makes the application using a CNN be able to control the privacy loss represented as the ratio of the probabilistic accuracies for original IFM and sanitized IFM.
