ABSTRACT
In the cognitive physics approach, a concept is represented in terms of a physical atom model, the interactions between objects are expressed by means of field, and the hierarchical structure is represented by means of granularity. Meanwhile, the state transformation in the discovery state space is applied to carry out the induction and reduction from original data space to feature space and further to concept space. In concept space, the natural states, which are multiscaled and multigranular, correspond to multiple knowledge states, i.e., the knowledge and mode to be discovered.
