Cornell researchers have developed a fairer system for recommendations – from hotels to jobs to videos – so a few top hits don’t get all the exposure.
A Theoretical Analysis of Normalized Discounted Cumulative Gain (NDCG) Ranking Measures
Ranking Ranking measures NDCG Consistent Distinguishability
2016/1/23
A central problem in ranking is to design a measure for evaluation of ranking functions. In this paper we study, from a theoretical perspective, the Normalized Discounted Cumulative Gain (NDCG) which ...
Z-Ranking:Using Statistical Analysis to Counter the Impact of Static Analysis Approximations
Z-Ranking Statistical Analysis Static Analysis Approximations
2015/8/7
This paper explores z-ranking, a technique to rank error reports emitted by static program checking analysis tools. Such tools often use approximate analysis schemes, leading to false error reports. T...
Static program checking tools can find many serious bugs in software, but due to analysis limitations they also frequently emit false error reports. Such false positives can easily render the error ch...

Most of existing work on sports video analysis concentrates on highlight extraction. Few efforts devoted to the important issue as how to organize the extracted highlights which is adapt for the...
A General Magnitude-Preserving Boosting Algorithm for Search Ranking
Directed distance function (DDF) magnitude-preserving pairwise-preference
2008/9/10
Traditional boosting algorithms for the ranking problems usually employ the pairwise approach and convert the document rating preference into a binary-value label, like RankBoost. However, such a pair...
