Spectrum Data Poisoning with Adversarial Deep Learning

no code implementations26 Jan 2019 Yi Shi, Tugba Erpek, Yalin E. Sagduyu, Jason H. Li

We consider the case that a cognitive transmitter senses the spectrum and transmits on idle channels determined by a machine learning algorithm.

Generative Adversarial Networks for Black-Box API Attacks with Limited Training Data

no code implementations25 Jan 2019 Yi Shi, Yalin E. Sagduyu, Kemal Davaslioglu, Jason H. Li

The exploratory attack with limited training data is shown to fail to reliably infer the target classifier of a real text classifier API that is available online to the public.

Active Deep Learning Attacks under Strict Rate Limitations for Online API Calls

no code implementations5 Nov 2018 Yi Shi, Yalin E. Sagduyu, Kemal Davaslioglu, Jason H. Li

To mitigate the impact of limited training data, we develop an active learning approach that first builds a classifier based on a small number of API calls and uses this classifier to select samples to further collect their labels.
