Cold-Start Expert Finding in Community Question Answering via Graph Regularizationt finding is important to many real applications such as question routing and identification of best answers. Currently, many approaches of expert findings rely heavily on the past question-answering activities of the users in order to build user models. However, the past question-answering activiti

Mining Correlations on Massive Bursty Time Series Collectionsaper, we present a novel approach for mining correlation in collections consisting of a large number of time series. In our approach, we use bursts co-occurring in different streams as the measure of their relatedness. By exploiting the pruning properties of our measure we develop new indexing struc

Adaptive Grid-Based k-median Clustering of Streaming Data with Accuracy Guaranteepartitions stream data into cells, derives statistical information of the cells, and then applies clustering on these much smaller statistical information without referring to the input data. Therefore, grid-based clustering is efficient and very suitable for high-throughput data streams, which are
