Webhandle the task with the tweet stream in real-time, we propose in this paper TopicSketch, a novel sketch-based topic model together with a set of techniques to achieve real-time detection. We evaluate our solution on a tweet stream with over 30 million tweets. Our experiment results show both efficiency and effectiveness of our approach.

WebA Novel Method for Time Series Anomaly Detection based on Segmentation and Clustering Abstract: There have been several algorithms for anomaly detection in time series data. However, most of them suffer from high computational cost and hence can not suit real world applications well. WebIn addition, subsequence anomaly detection methods usually require access to the entire dataset and are not able to learn and detect anomalies in streaming settings. To address …
