The dynamical system is trivially vector addition: x1=f(x0,u0)=x0+u0. I use Support Vector Machine (SVM) with a batch training set as an example below: The state is the learner’s model h:X↦Y. The book is available from the publishing company Athena Scientific, or from Amazon.com.. Click here for an extended lecture/summary of the book: Ten Key Ideas for Reinforcement Learning and Optimal Control. /Type /XObject Stochastic Optimal Control and Optimization of Trading Algorithms. When optimization algorithms are further recast as controllers, the ultimate goal of training processes can be formulated as an optimal control problem. 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. An optimal control problem with discrete states and actions and probabilistic state transitions is called a Markov decision process (MDP). The adversary’s goal is for the “wrong” model to be useful for some nefarious purpose. The modern day machine learning is defined as ‘the field of study that gives computers the ability to learn without being explicitly programmed.’ By Arthur Samuel in 1959. %PDF-1.5 Machine Learning In machine learning, kernel methods are used to study The control input is ut∈Ut with Ut=R in the unconstrained shaping case, or the appropriate Ut if the rewards must be binary, for example.

Let us consider the study of brain disorders and the research efforts to come up with efficient methods to therapeutically intervene in its function. /FormType 1 share. The adversary’s goal is to use minimal reward shaping to force the learner into performing specific wrong actions. 2. 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. One of the aims of the book is to explore the common boundary between artificial intelligence and optimal control, and to form a bridge that is … 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 quality of control is specified by the running cost: which defines the step-by-step control cost, Proceedings of the 17th ACM SIGKDD international conference Towards black-box iterative machine teaching. Kwang-Sung Jun, Lihong Li, Yuzhe Ma, and Xiaojin Zhu. Machine teaching: an inverse problem to machine learning and an These adversarial examples do not even need to be successful attacks. The distance function is domain-dependent, though in practice the adversary often uses a mathematically convenient surrogate such as some p-norm ∥x−x′∥p. INTRODUCTION Machine learning and control theory are two foundational but disjoint communities. Conversely Machine Learning can be used to solve large control problems. Optimal control theory aims to find the control inputs required for a system to perform a task optimally with respect to a predefined objective. /Subtype /Form For example, x. denotes the state in control but the feature vector in machine learning. To simplify the exposition, I focus on adversarial reward shaping against stochastic multi-armed bandit, because this does not involve deception through perceived states. Anthony D. Joseph, Blaine Nelson, Benjamin I. P. Rubinstein, and J. D. Tygar. Acknowledgments. /Length 15 Adversarial attacks on stochastic bandits. Browse our catalogue of tasks and access state-of-the-art solutions. ∙ Intelligence (IJCAI). This talk will focus on fundamental connections between control theory and machine learning. More generally, W∗ can be a polytope defined by multiple future classification constraints. /Subtype /Form endstream These problems call for future research from both machine learning and control communities. Machine learning control (MLC) is a subfield of machine learning, intelligent control and control theory which solves optimal control problems with methods of machine learning. 30 0 obj This change represents a truly fundamental departure from traditional classification and regression … With a team of extremely dedicated and quality lecturers, stochastic optimal control in machine learning will not only be a place to share knowledge but also to help students get inspired to explore and discover many creative ideas from … Types of problems and tasks. ... policy gradient method on the mixed H2/H-infinity state feedback design problem and the Markovian jump linear quadratic optimal control problem. Optimal control focuses on a subset of problems, but solves these problems very well, and has a rich history. For example, the learner may perform one step of gradient descent: The adversary’s running cost gt(wt,ut) typically measures the effort of preparing ut. Optimal Adversarial Attack on Autoregressive Models, Robust Deep Learning as Optimal Control: Insights and Convergence One of the aims of the book is to explore the common boundary between artificial intelligence and optimal control, and to form a bridge that is accessible by workers with background in either field. 4 1 14. Machine learning discovers statistical knowledge from data and has escaped from the cage of perception. Lastly, the proposed learning method is aligned with the recent surge of machine learning techniques with integrated physics knowledge. /BBox [0 0 16 16] Stackelberg games for adversarial prediction problems. share.
