This book demonstrates the optimal adversarial attacks against several important signal processing algorithms. Through presenting the optimal attacks in wireless sensor networks, array signal processing, principal component analysis, etc, the authors reveal the robustness of the signal processing algorithms against adversarial attacks. Since data quality is crucial in signal processing, the adversary that can poison the data will be a significant threat to signal processing. Therefore, it is necessary and urgent to investigate the behavior of machine learning algorithms in signal processing under adversarial attacks. The authors in this book mainly examine the adversarial robustness of three commonly used machine learning algorithms in signal processing respectively: linear regression, LASSO-based feature selection, and principal component analysis (PCA). As to linear regression, the authors derive the optimal poisoning data sample and the optimal feature modifications, and also demonstrate the effectiveness of the attack against a wireless distributed learning system. The authors further extend the linear regression to LASSO-based feature selection and study the best strategy to mislead the learning system to select the wrong features. The authors find the optimal attack strategy by solving a bi-level optimization problem and also illustrate how this attack influences array signal processing and weather data analysis. In the end, the authors consider the adversarial robustness of the subspace learning problem. The authors examine the optimal modification strategy under the energy constraints to delude the PCA-based subspace learning algorithm. This book targets researchers working in machine learning, electronic information, and information theory as well as advanced-level students studying these subjects. R&D engineers who are working in machine learning, adversarial machine learning, robust machine learning, and technical consultants working on the security and robustness of machine learning are likely to purchase this book as a reference guide.

Snapchat. WhatsApp. Ashley Madison. Fitbit. Tinder. Periscope. How do we make sense of how apps like these-and thousands of others-have embedded themselves into our daily routines, permeating the background of ordinary life and standing at-the-ready to be used on our smartphones and tablets? When we look at any single app, it's hard to imagine how such a small piece of software could be particularly notable. But if we look at a collection of them, we see a bigger picture that reveals how the quotidian activities apps encompass are far from banal: connecting with friends (and strangers and enemies), sharing memories (and personally identifying information), making art (and trash), navigating spaces (and reshaping places in the process). While the sheer number of apps is overwhelming, as are the range of activities they address, each one offers an opportunity for us to seek out meaning in the mundane. Appified is the first scholarly volume to examine individual apps within the wider historical and cultural context of media and cultural studies scholarship, attuned to issues of politics and power, identity and the everyday.
