DeepDefense: Robust Learning via Layer-Wise Gradient-Feature Alignment
Ci Lin, Tet Yeap, Iluju Kiringa
Deep neural networks are known to be vulnerable to adversarial perturbations, which are small, carefully crafted inputs that lead to incorrect predictions. In this paper, we propos…
Robust Bidirectional Associative Memory via Regularization Inspired by the Subspace Rotation Algorithm
Ci Lin, Tet Yeap, Iluju Kiringa
Bidirectional Associative Memory (BAM) trained with Bidirectional Backpropagation (B-BP) often suffers from poor robustness and high sensitivity to noise and adversarial attacks. T…
Single image sensorless adaptive optics using phase-diversified multifocal array
Biwei Zhang, Qi Hu, Jingyu Wang +1
Image-based sensorless adaptive optics is commonly used to improve microscope image quality through aberration compensation. However, its sequential nature leads to repeated sample…
Information-guided optimization of image-based sensorless adaptive optics methods
Biwei Zhang, Martin J. Booth, Qi Hu
Adaptive optics (AO) are reconfigurable devices that compensate for wavefront distortions or aberrations in optical systems such as microscopes, telescopes and ophthalmoscopes. Abe…
