From Group to Individual Labels Using Deep Features
TL;DR: This paper proposes a new objective function that encourages smoothness of inferred instance-level labels based on instance- level similarity, while at the same time respecting group-level label constraints, and applies this approach to the problem of predicting labels for sentences given labels for reviews, using a convolutional neural network to infer sentence similarity.
Proceedings Article
A probabilistic approach to fast pattern matching in time series databases
Eamonn Keogh,Padhraic Smyth +1 more
TL;DR: The proposed approach provides a natural framework to support user-customizable "query by content" on time series data, taking prior domain information into account in a principled manner.
Journal ArticleDOI
Cluster Analysis of Typhoon Tracks. Part II: Large-Scale Circulation and ENSO
TL;DR: In this article, a probabilistic clustering method based on a regression mixture model was used to describe tropical cyclone propagation in the western North Pacific (WNP) and seven clusters were obtained and described in Part I of this two-part study.
Journal ArticleDOI
Model-Based Clustering and Visualization of Navigation Patterns on a Web Site
TL;DR: A new methodology for exploring and analyzing navigation patterns on a web site that clusters users according to the order in which they request web pages using a mixture of first-order Markov models using the Expectation-Maximization algorithm.
