Harnessing Context for Budget-Limited Crowdsensing With Massive Uncertain Workers
نویسندگان
چکیده
Crowdsensing is an emerging paradigm of ubiquitous sensing, through which a crowd workers are recruited to perform sensing tasks collaboratively. Although it has stimulated many applications, open fundamental problem how select among massive number given task under limited budget. Nevertheless, due the proliferation smart devices equipped with various sensors, very difficult profile in terms ability. uncertainties can be addressed by conventional Combinatorial Multi-Armed Bandit (CMAB) framework trade-off between exploration and exploitation, we do not have sufficient allowance directly explore exploit Furthermore, since sensor usually quite resources, may bounded capabilities only few times, further restricts our opportunities learn uncertainty. To address above issues, propose Context-Aware Worker Selection (CAWS) algorithm this paper. By leveraging correlation context information their abilities, CAWS aims at maximizing expected cumulative revenue efficiently both budget constraint capacity constraints respected, even when uncertain massive. The efficacy verified rigorous theoretical analysis extensive experiments.

Immunizing complex networks with limited budget
In this letter we studied the epidemic spreading on scale-free networks assuming a limited budget for immunization. We proposed a general model in which the immunity of an individual against the disease depends on its immunized friends in the network. Furthermore, we considered the possibility that each individual might be eager to pay a price to buy the vaccine and become immune against the di...

متن کاملHarnessing Context for Vandalism Detection in Wikipedia
The importance of collaborative social media (CSM) applications such as Wikipedia to modern free societies can hardly be overemphasized. By allowing end users to freely create and edit content, Wikipedia has greatly facilitated democratization of information. However, over the past several years, Wikipedia has also become susceptible to vandalism, which has adversely affected its information qu...
متن کاملHarnessing Context Incongruity for Sarcasm Detection
The relationship between context incongruity and sarcasm has been studied in linguistics. We present a computational system that harnesses context incongruity as a basis for sarcasm detection. Our statistical sarcasm classifiers incorporate two kinds of incongruity features: explicit and implicit. We show the benefit of our incongruity features for two text forms tweets and discussion forum pos...
متن کاملFeedback Control for Uncertain Systems with Limited Data Rates
This paper addresses the stabilization problem for stochastic uncertain systems with bounded process disturbance, where sensors, controllers and plants are connected by a digital communication channel. A lower bound on data rates of the channel, above which there exists a quantization, coding and control policy to stabilize the unstable plant in the mean square sense. A sufficient condition for...
