- Abstract
This paper proposes a trace rule based self-organized map (SOM) model built upon a sparse 2-stage deep belief network (DBN). The combination of SOM and sparse DBN forms a hierarchical network where DBN serves as a V2 features detector while SOM layer learns to extract transformation invariant features guided by trace learning rule during training phase. The performance of our proposed method is evaluated by stimulus specific information (SSI) measuring and comparison with classic algorithms. It is demonstrated that trace rule based SOM model can generate more neurons with high SSI value which is beneficial to convey more useful and discriminative information for further object recognition.
