The complexity of online manipulation of sequential elections
Journal of Computer and System Sciences, 2014 Most work on manipulation assumes that all preferences are known to the manipulators. However, in many settings elections are open and sequential, and manipulators may know the already cast votes but may not know the future votes. We introduce a framework, in which manipulators can see the past votes but not the future ones, to model online coalitional

The Perils of Online Manipulation
2015 48th Hawaii International Conference on System Sciences, 2015Online platforms are prone to abuse and manipulations from strategic parties. For example, social media and review websites suffer from sentiment manipulations, manifested in the form of opinion spam and fake reviews. The consequence of such manipulations is the deterioration of information quality as well as loss in consumer welfare.

Local online planning of coordinated manipulation motion
2015 IEEE International Conference on Robotics and Automation (ICRA), 2015In this work, we deal with the problem of planning a manipulation task for a robotic system composed of at least one dexterous arm and a dexterous multi-fingered hand. The goal of the local planner is to include both, the arm and the hand, in the execution of the task in a coordinated way.

Consumer responses toward online review manipulation
Journal of Research in Interactive Marketing, 2014Purpose – This paper aims to explore the effect on consumer responses of firms’ manipulating online reviews based on review valence (positive vs negative) and the relationship between consumer trust and purchase intentions. Design/methodology/approach – This study

Online entropy manipulation: stochastic information gradient
IEEE Signal Processing Letters, 2003Entropy has found significant applications in numerous signal processing problems including independent components analysis and blind deconvolution. In general, entropy estimators require O(N/sup 2/) operations, N being the number of samples. For practical online entropy manipulation, it is desirable to determine a stochastic gradient for entropy ...

Online Active Safety for Robotic Manipulators
2019 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2019Future manufacturing environments will see an increased need for cooperation between humans and machines. In this paper we propose a method that allows industrial manipulators to safely operate around humans. This approach guarantees that the manipulator will never collide with human operators while performing its normal tasks.

Uncovering Crowdsourced Manipulation of Online Reviews
Proceedings of the 38th International ACM SIGIR Conference on Research and Development in Information Retrieval, 2015Online reviews are a cornerstone of consumer decision making. However, their authenticity and quality has proven hard to control, especially as polluters target these reviews toward promoting products or in degrading competitors. In a troubling direction, the widespread growth of crowdsourcing platforms like Mechanical Turk has created a large-scale ...

The Problem of Online Manipulation
SSRN Electronic Journal, 2019Recent controversies have led to public outcry over the risks of online manipulation. Leaked Facebook documents discussed how advertisers could target teens when they feel particularly insecure or vulnerable. Cambridge Analytica suggested that its psychographic profiles enabled political campaigns to exploit individual vulnerabilities online.
