Authors: Guan-Horng Liu, Evangelos A. Theodorou. It should be noted that the adversary’s goal may not be the exact opposite of the learner’s goal: the target arm i∗ is not necessarily the one with the worst mean reward, and the adversary may not seek pseudo-regret maximization.

There are a number of potential benefits in taking the optimal control view: It offers a unified conceptual framework for adversarial machine learning; The optimal control literature provides efficient solutions when the dynamics f is known and one can take the continuous limit to solve the differential equations [15]; Reinforcement learning, either model-based with coarse system identification or model-free policy iteration, allows approximate optimal control when f is unknown, as long as the adversary can probe the dynamics [9, 8]; A generic defense strategy may be to limit the controllability the adversary has over the learner. share, The fragility of deep neural networks to adversarially-chosen inputs has... endobj The control u0 is a whole training set, for instance u0={(xi,yi)}1:n. The control constraint set U0 consists of training sets available to the adversary; if the adversary can arbitrary modify a training set for supervised learning (including changing features and labels, inserting and deleting items), this could be U0=∪∞n=0(X×Y)n, namely all training sets of all sizes. 3.1.

Abstract: Attempts from different disciplines to provide a fundamental understanding of deep learning have advanced rapidly in recent years, yet a unified framework remains relatively limited. Adversarial training can be viewed as a heuristic to approximate the uncountable constraint (. This change represents a truly fundamental departure from traditional classification and regression … For the SVM learner, this would be empirical risk minimization with hinge loss ℓ() and a regularizer: The batch SVM does not need an initial weight w0.

The dynamics is the sequential update algorithm of the learner. endstream Section 3 will present the algorithms and analyze the attributes used for the machine learning, the results of which are presented in Section 4. This control view on test-time attack is more interesting when the adversary’s actions are sequential U0,U1,…, and the system dynamics render the action sequence non-commutative. For adversarial machine learning applications the dynamics f is usually highly nonlinear and complex. In Guy Lebanon and S. V. N. Vishwanathan, editors, Proceedings and the terminal cost for finite horizon: which defines the quality of the final state. (AAAI-16). With these definitions this is a one-step control problem (4) that is equivalent to the test-time attack problem (9). The method we introduce is thus distinctively different from active learning, as we choose data based on the optimality conditions of TO, which are problem-dependent and theory-driven. The dynamics st+1=f(st,ut) is straightforward via empirical mean update (12), TIt increment, and new arm choice (11). /Resources 35 0 R The 27th International Joint Conference on Artificial /FormType 1 INTRODUCTION Machine learning and control theory are two foundational but disjoint communities.

Non-Asymptotic View, Learning a Family of Optimal State Feedback Controllers, Bridging Cognitive Programs and Machine Learning. Of course, the resulting control problem (4) does not directly utilize adversarial examples. Some of these applications will be discussed below. Duke MEMS researchers are at work on new control, optimization, learning, and artificial intelligence (AI) methods for autonomous dynamical systems that can make independent intelligent decisions and learn in uncertain, unstructured, and unpredictable environments. The function f defines the evolution of state under external control. With adversarial reward shaping, an adversary fully observes the bandit. 0 Get the week's most popular data science and artificial intelligence research sent straight to your inbox every Saturday. The dynamical system is trivially vector addition: x1=f(x0,u0)=x0+u0. It is more "flexible", albeit, not as rigorous. One-step control has not been the focus of the control community and there may not be ample algorithmic solutions to borrow from. Her current research interests include machine learning in control, security of cyber-physical systems, game theory, and distributed control. ∙ ∙ When f is not fully known, the problem becomes either robust control where control is carried out in a minimax fashion to accommodate the worst case dynamics [28], or reinforcement learning where the controller probes the dynamics [23]. The adversary’s running cost gt then measures the effort in performing the action at step t. I mention in passing that the optimal control view applies equally to machine teaching [29, 27], and thus extends to the application of personalized education [24, 22]. Duke MEMS researchers are at work on new control, optimization, learning, and artificial intelligence (AI) methods for autonomous dynamical systems that can make independent intelligent decisions and learn in uncertain, unstructured, and unpredictable environments. The learner’s goal is to minimize the pseudo-regret Tμmax−E∑Tt=1μIt where μi=Eνi and μmax=maxi∈[k]μi.
