Domain-oriented Data-driven Data Mining and Granular Cognitive Computing (3DM&GCC)

Short Description: There are two related parts in this tutorial talk, that is, domain-oriented data-driven data mining (3DM) and granular cognitive computing (GCC). In the 3DM part, a new data mining model of domain-oriented data-driven data mining is introduced. Data is taken as a format for encoding information and knowledge, like brain and book. Data mining is a process of transforming the information and knowledge from data format (which is unstructured, and not understandable for human) into a structured format understandable for human. The characteristics of the knowledge in data should remain unchanged in a data mining process. Some knowledge characteristics, e.g. uncertainty degree, are studied and extracted (measured) from data at first. These knowledge characteristics are used to control the data mining process and thus not changed in the process. This is a data driven data mining process. In a domain oriented data mining process, users are allowed to suggest preferred classifiers and structures; an interactive manner between users and machines is used; its input and output are interleaved, like a conversation; users can freely explore the dataset according to their preference and priority, ensure that each classification stage and the corresponding results are all understandable and comprehensible. Some case studies of 3DM are introduced and future studies of 3DM are discussed.
In the GCC part, inspired by human’s granularity thinking based problem solving mechanism and the cognition law of global precedence“, a data-driven granular cognitive computing model (DGCC) is further introduced. It integrates two contradictory mechanisms, that is, human’s cognition mechanism of “global precedence” which is a cognition process of “from coarser to finer” and the information processing mechanism of machine learning systems which is “from finer to coarser”. According to DGCC, deep learning is taken as a combination of symbolism and connectionism, and named hierarchical structuralism (HS). Some characteristics of HS and key research problems about DGCC are addressed.
