Nearest Neighbor-Based Classification of Uncertain Data
Fabrizio Angiulli, Fabio Fassetti
Article No.: 1
DOI: 10.1145/2435209.2435210

This work deals with the problem of classifying uncertain data. With this aim we introduce the Uncertain Nearest Neighbor (UNN) rule, which represents the generalization of the deterministic nearest neighbor rule to the case in which uncertain...

Comparative Document Summarization via Discriminative Sentence Selection
Dingding Wang, Shenghuo Zhu, Tao Li, Yihong Gong
Article No.: 2
DOI: 10.1145/2435209.2435211

Given a collection of document groups, a natural question is to identify the differences among these groups. Although traditional document summarization techniques can summarize the content of the document groups one by one, there exists a great...

Message-Passing Algorithms for Sparse Network Alignment
Mohsen Bayati, David F. Gleich, Amin Saberi, Ying Wang
Article No.: 3
DOI: 10.1145/2435209.2435212

Network alignment generalizes and unifies several approaches for forming a matching or alignment between the vertices of two graphs. We study a mathematical programming framework for network alignment problem and a sparse variation of it where...

Confidence Weighted Mean Reversion Strategy for Online Portfolio Selection
Bin Li, Steven C. H. Hoi, Peilin Zhao, Vivekanand Gopalkrishnan
Article No.: 4
DOI: 10.1145/2435209.2435213

Online portfolio selection has been attracting increasing attention from the data mining and machine learning communities. All existing online portfolio selection strategies focus on the first order information of a portfolio vector, though the...
