Exploring the space of adversarial images [PDF]

2016 International Joint Conference on Neural Networks (IJCNN), 2016
Adversarial examples have raised questions regarding the robustness and security of deep neural networks. In this work we formalize the problem of adversarial images given a pretrained classifier, showing that even in the linear case the resulting optimization problem is nonconvex.

Learn Generalization Feature via Convolutional Neural Network: A Fault Diagnosis Scheme Toward Unseen Operating Conditions

IEEE Access, 2020
In recent years, Convolutional neural networks (CNNs) have achieved start-of-art performance in the fault diagnosis field. If there is no available information on the unseen operating conditions, the model trained on the seen operating condition cannot ...

Exploring the Intermembrane Space [PDF]

ACS Chemical Biology, 2007
Despite the importance that many components of the intermembrane space (IMS) of mitochondria play in cellular function, the targeting sequences that are responsible for transporting proteins to this subcellular compartment are not fully understood.

Imaging in Space Exploration [PDF]

American Journal of Neuroradiology, 2011
I remember the amazement I felt when man walked on the moon. Today, I feel that monies spent on space exploration would be better used in green energy and ocean preservation programs. We already live on earth, the most perfect spaceship of all: Why go beyond it?
