Optimal Crowd-Powered Rating and Filtering Algorithms
We focus on crowd-powered ltering, i.e., ltering a large set of items using humans. Filtering is one of the most commonly used building blocks in crowdsourcing applications and systems. While solutions for crowd-powered ltering exist, theymake a range of implicit assumptions and restrictions, ultimately rendering them not powerful enough for real-world applications. We describe two approache...
متن کاملOptimal Worker Quality and Answer Estimates in Crowd-Powered Filtering and Rating
We consider the problem of optimally filtering (or rating) a set of items based on predicates (or scoring) requiring human evaluation. Filtering and rating are ubiquitous problems across crowdsourcing applications. We consider the setting where we are given a set of items and a set of worker responses for each item: yes/no in the case of filtering and an integer value in the case of rating. We ...
متن کاملCrowd-Powered Intelligent Systems
Human computation provides a new resource for creating intelligent systems that are able to go beyond the capabilities of fully-automated solutions. Currently, machines struggle in many real-world settings because problems can be almost entirely unconstrained and can vary greatly between instances. Solving problems such as natural language understanding require artificial intelligence to first ...
متن کاملElectrocardiogram Compression and Optimal ECG Filtering Algorithms
In this paper novel compression techniques are developed for portable heart-monitoring equipment that could also form the basis for more intelligent diagnostic systems thanks to the way the compression algorithms depend on signal classification. There are two main categories of compression which are employed for electrocardiogram signals: lossless and lossy. Design of an optimal Wiener filter i...
متن کاملImplicit Rating and Filtering
Social filtering systems that use explicit ratings require a large number of ratings to remain viable. The effort involved for a user to rate a document may outweigh any benefit received, leading to a shortage of ratings. One approach to this problem is to use implicit ratings: where user actions are recorded and a rating is inferred from the recorded data. This paper discusses the costs and be...
