Reverse top-k queries

open access: yes2010 IEEE 26th International Conference on Data Engineering (ICDE 2010), 2010
Rank-aware query processing has become essential for many applications that return to the user only the top-k objects based on the individual user's preferences. Top-k queries have been mainly studied from the perspective of the user, focusing primarily on efficient query processing.

Top-k Hierarchical Classification

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2017
This paper studies a top-k hierarchical classification problem. In top-k classification, one is allowed to make k predictions and no penalty is incurred if at least one of k predictions is correct. In hierarchical classification, classes form a structured hierarchy, and misclassification costs depend on the relation between the correct ...

Top-k pipe join

2010 IEEE 26th International Conference on Data Engineering Workshops (ICDEW 2010), 2010
In the context of service composition and orchestration, service invocation is typically scheduled according to execution plans, whose topology establishes whether different services are to be invoked in parallel or in a sequence. In the latter case, we may have a configuration, called pipe join, in which the output of a service is used as input for ...

Top-k spatial joins

IEEE Transactions on Knowledge and Data Engineering, 2005
Given two spatial data sets A and B, a top-k spatial join retrieves the k objects from A or B that intersect the largest number of objects from the other data set. Depending on the application requirements, there exist several variations of the problem.

TOP-K selective gossip

2012 IEEE 13th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2012
Many distributed signal processing problems involve aggregating vectors of data, and often we are interested in the largest entries of the aggregate vector. For example, in distributed particle filtering one may be interested in fusing information about particles with the largest weights.

Top-k bounded diversification

Proceedings of the 2012 ACM SIGMOD International Conference on Management of Data, 2012
This paper investigates diversity queries over objects embedded in a low-dimensional vector space. An interesting case is provided by spatial Web objects, which are produced in great quantity by location-based services that let users attach content to places, and arise also in trip planning, news analysis, and real estate scenarios.

DC-Top-k: A Novel Top-k Selecting Algorithm and Its Parallelization

2016 45th International Conference on Parallel Processing (ICPP), 2016
Sorting is a basic computational task in Computer Science. As a variant of the sorting problem, top-k selecting have been widely used. To our knowledge, on average, the state-of-the-art top-k selecting algorithm Partial Quicksort takes C(n, k) = 2(n+1)Hn+2n-6k+6-2(n+3-k)Hn+1-k comparisons and about C(n, k)/6 exchanges to select the largest k terms from

Top-k Parametrized Boost

2014
Ensemble methods such as AdaBoost are popular machine learning methods that create highly accurate classifier by combining the predictions from several classifiers. We present a parametrized method of AdaBoost that we call Top-k Parametrized Boost. We evaluate our and other popular ensemble methods from a classification perspective on several real ...
