Duration Normalization Algorithm Based on Feature Space Trajectory in Pathological Speech Recognition

2018

In this paper, a Duration Normalization algorithm is presented based on feature space trajectory to improve the accuracy in pathological speech recognition. In this method, speech MFCC features are divided into K segments dynamically, then …

LaserGuider: A Laser Based Physical Backdoor Attack against Deep Neural Networks

2024 · arXiv (Cornell University)

Backdoor attacks embed hidden associations between triggers and targets in deep neural networks (DNNs), causing them to predict the target when a trigger is present while maintaining normal behavior otherwise. Physical backdoor attacks, which use …
