Actionable intelligence and online learning for semantic computing
(World Scientific Publishing Company, 2017)As the world becomes more connected and instrumented, high dimensional, heterogeneous and time-varying data streams are collected and need to be analyzed on the fly to extract the actionable intelligence from the data ... -
Adaptive contextual learning for unit commitment in microgrids with renewable energy sources
(Institute of Electrical and Electronics Engineers, 2018)In this paper, we study a unit commitment (UC) problem where the goal is to minimize the operating costs of a microgrid that involves renewable energy sources. Since traditional UC algorithms use a priori information about ... -
Adaptive ensemble learning with confidence bounds for personalized diagnosis
(AAAI Press, 2016)With the advances in the field of medical informatics, automated clinical decision support systems are becoming the de facto standard in personalized diagnosis. In order to establish high accuracy and confidence in ... -
Analysis of thompson sampling for combinatorial multi-armed bandit with probabilistically triggered arms
(PLMR, 2020)We analyze the regret of combinatorial Thompson sampling (CTS) for the combinatorial multi-armed bandit with probabilistically triggered arms under the semi-bandit feedback setting. We assume that the learner has access ... -
The biobjective multiarmed bandit: learning approximate lexicographic optimal allocations
(TÜBİTAK, 2019)We consider a biobjective sequential decision-making problem where an allocation (arm) is called ϵ lexicographic optimal if its expected reward in the first objective is at most ϵ smaller than the highest expected reward, ... -
Combinatorial Gaussian process bandits with probabilistically triggered arms
(Microtome Publishing, 2021)Combinatorial bandit models and algorithms are used in many sequential decision-making tasks ranging from item list recommendation to influence maximization. Typical algorithms proposed for combinatorial bandits, including ... -
Combinatorial multi-armed bandit problem with probabilistically triggered arms: a case with bounded regret
(IEEE, 2017-11)In this paper, we study the combinatorial multi-armed bandit problem (CMAB) with probabilistically triggered arms (PTAs). Under the assumption that the arm triggering probabilities (ATPs) are positive for all arms, we prove ... -
Conservative policy construction using variational autoencoders for logged data with missing values
(Institute of Electrical and Electronics Engineers Inc., 2022-01-10)In high-stakes applications of data-driven decision-making such as healthcare, it is of paramount importance to learn a policy that maximizes the reward while avoiding potentially dangerous actions when there is uncertainty. ... -
Context-aware hierarchical online learning for performance maximization in mobile crowdsourcing
(Institute of Electrical and Electronics Engineers, 2018)In mobile crowdsourcing (MCS), mobile users accomplish outsourced human intelligence tasks. MCS requires an appropriate task assignment strategy, since different workers may have different performance in terms of acceptance ... -
Contextual learning for unit commitment with renewable energy sources
(IEEE, 2017)In this paper, we study a unit commitment (UC) problem minimizing operating costs of the power system with renewable energy sources. We develop a contextual learning algorithm for UC (CLUC) which learns which UC schedule ... -
Decentralized dynamic rate and channel selection over a shared spectrum
(IEEE, 2021-03-15)We consider the problem of distributed dynamic rate and channel selection in a multi-user network, in which each user selects a wireless channel and a modulation and coding scheme (corresponds to a transmission rate) in ... -
eTutor: online learning for personalized education
(IEEE, 2015-04)Given recent advances in information technology and artificial intelligence, web-based education systems have became complementary and, in some cases, viable alternatives to traditional classroom teaching. The popularity ... -
Exploiting relevance for online decision-making in high-dimensions
(IEEE, 2020)Many sequential decision-making tasks require choosing at each decision step the right action out of the vast set of possibilities by extracting actionable intelligence from high-dimensional data streams. Most of the times, ... -
Fast learning for dynamic resource allocation in AI-Enabled radio networks
(IEEE, 2020)Artificial Intelligence (AI)-enabled radios are expected to enhance the spectral efficiency of 5th generation (5G) millimeter wave (mmWave) networks by learning to optimize network resources. However, allocating resources ... -
Feedback adaptive learning for medical and educational application recommendation
(IEEE, 2020)Recommending applications (apps) to improve health or educational outcomes requires long-term planning and adaptation based on the user feedback, as it is imperative to recommend the right app at the right time to improve ... -
Finding it now: networked classifiers in real-time stream mining systems
(Springer, Cham, 2019)The aim of this chapter is to describe and optimize the specifications of signal processing systems, aimed at extracting in real time valuable information out of large-scale decentralized datasets. A first section will ... -
Functional contour-following via haptic perception and reinforcement learning
(Institute of Electrical and Electronics Engineers, 2018)Many tasks involve the fine manipulation of objects despite limited visual feedback. In such scenarios, tactile and proprioceptive feedback can be leveraged for task completion. We present an approach for real-time haptic ... -
Gambler's ruin bandit problem
(IEEE, 2017)In this paper, we propose a new multi-armed bandit problem called the Gambler's Ruin Bandit Problem (GRBP). In the GRBP, the learner proceeds in a sequence of rounds, where each round is a Markov Decision Process (MDP) ... -
