Dependable Deep Computation Model for Feature Learning on Big Data in Cyber-Physical Systems

2018 · ACM Transactions on Cyber-Physical Systems

With the ongoing development of sensor devices and network techniques, big data are being generated from the cyber-physical systems. Because of sensor equipment occasional failure and network transmission unreliability, a large number of low-quality data, …

Noise Suppression for Improved Few-Shot Learning

2022 · ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)

Few-shot learning (FSL) aims to generalize from few labeled samples. Recently, metric-based methods have achieved surprising classification performance on many FSL benchmarks. However, those methods ignore the impact of noise, making the few-shot learning still …

Fake Reviewer Group Detection in Online Review Systems

2021 · arXiv (Cornell University)

Online review systems are important components in influencing customers' purchase decisions. To manipulate a product's reputation, many stores hire large numbers of people to produce fake reviews to mislead customers. Previous methods tackle this problem …
