Speech Title: Big Data, Semantics, Their Relationships, and Their Methodologies

Abstract: Big data analysis has been booming for a several years and various methodologies have been proposed to the solutions to big data analysis. Its purpose is to discover patterns of bid data, reveal new relationships/links among the big data, and thus predict what will happen in the future. At moment such big data analysis is beset by the “pure” data analysis methods without human being’s strong involvement and interference. An example in this direction is machine translation – learning to translate from massive translation instances. However, profound understanding of data, their relationships, and sematic discovery depend on the acquisition, understanding, and representation of concepts (the connotation of data), whereas the values of the data can be considered to be the extension. Various relationships among concepts, such as part-whole, internal-external, inter-layers, and “material-element” are a few typical semantic relationships that describe better the characteristics of big data and hence provide an innovative view toward big data analysis. This talk intends to open up a door to semantic analysis of big data as well as connections from data to concepts.

Speech Title: Towards Explainable and Stable Prediction

Abstract: Predicting unknown outcome values based on their observed features using a model estimated on a training data set is a common statistical problem. Many machine learning and data mining methods have been proposed and shown to be successful when the test data and training data come from the same distribution. However, the best-performing models for a given distribution of training data typically exploit subtle statistical relationships among features, making them potentially more prone to prediction error when applied to test data sets where, for example, the joint distribution of features differs from that in the training data. Therefore, it can be useful to develop predictive algorithms that are robust to shifts in the environment, particularly in application areas where models cannot be retrained as quickly as the environment changes. In this talk, I will describe a view of this problem from correlation versus causality perspective, and describe a number of our recent efforts in this direction.

Speech title: Key technologies of stock forecasting models based on big data and crowd intelligence

Abstract: Along with the economic development, an increasing number of factors and high-order data have considerably influenced the fluctuations in stock market. Many existing studies have considered the spatio-temporal correlation of stock index but ignored the comprehensive influence of crowd intelligence on stock index with changes in time and space. Therefore, to improve the forecasting accuracy of the multi-factor and high-order time series stock forecasting models, some key technologies based on big data and crowd intelligence are explored, by combining knowledge graph, crowd sensing, semantic search, personalized recommendation, game theory, fuzzy time series, credit scoring, deep learning, etc. The experimental results demonstrate that the proposed model shows outstanding forecasting accuracy compared with the benchmark methods on the Shanghai Stock Exchange Composite Index and Taiwan Stock Exchange Capitalization Weighted Stock Index.
