Title:Concept-cognitive Learning for Social Network Analysis

Abstract: The characteristics of the massive social media data, diverse mobile sensing devices as well as the highly complex and dynamic user’s social behavioral patterns have led to the generation of huge amounts of high dimension, uncertain, imprecision, and noisy data from social networks. Thanks to the emerging soft computing techniques, unlike conventional hard computing, which are widely used for coping with the tolerance of imprecision, uncertainty, partial truth, and approximation. One of the most important and promising applications is social network analysis (SNA) which is the process of investigating social structures and relevant properties through the use of network and graph theories. In this talk, a novel concept-cognitive learning paradigm for social network analysis will be introduced. Specifically, the representation model of Social Networks using Formal Concept Analysis (FCA) is introduced first. Then, some of our latest research works on topological structures mining and analysis in Social Networks based on concept interestingness are presented. Finally, the relevant FCA-based SNA software packages are summarized.

Title: Machine learning for Stock forecasting

Abstract: This talk mainly introduces different models for stock forecasting, one model combines features selected by multiple feature selection techniques to generate an optimal feature subset and then use a deep generative model to predict future stock movements. Another model is for a turning point prediction method of stock price based on RVFL-GMDH and chaotic time series analysis. The turning indicator of time series is computed firstly; then, by applying the RVFL-GMDH model for the turning point prediction of the stock price. Computation results are reported.
