The increasing prevalence of smartphonesin our everyday life has opened up a window into the lives of smartphone users.Smartphones serve a wide variety of functions, and users can install and usemobile applications to achieve nearly every imaginable purpose. Since asmartphone is linked to an individual user, its applications can effectivelycapture large amounts of a user’s personal information. This information couldbe used to improve mobile devices, applications and services in various ways,such as personalized recommendation and adaptation, targeted advertising, anddesigning application interfaces according to users’ interests and preferences,so as to improve the mobile user experience. In this talk, I will show how tomine user attributes from app lists on smartphones, and how to discover usergroups from smartphone app usage behaviors. Two large-scale real-world datasetsconsisting of over 100,000 users were used for evaluation.
报告题目: DeepLearning of Graphs with Diagonal Ngram Convolutional Neural Networks
ConvolutionalNeural Network (CNN) has gained attractions in image analytics and speechrecognition in recent years. However, employing CNN for classification ofgraphs remains to be challenging. This talk presents the Ngram graph-blockbased convolutional neural network model for classification of graphs. Ourresults show that the Ngram approach outperforms existing methods with highaccuracy and comparable performance.
