A Temporal Sequence Processor Based on the Biological Reaction-diffusion Process.
Sylvian R. Ray, Hillol Kargupta · 1993
Temporal sequences are a fundamental form of information and communication both in natural and engineered systems. The biological control process which directs the generation of iterative structures from undifferentiated tissue is a type of temporal sequential process. A quantitative explanation of this temporal process is reaction-diffusion, initially proposed by Turing [1952] and later widely studied and elaborated. We have adapted the reaction-diffusion mechanism to create a temporal sequence processor(TSP) composed of cells in a diffusion-supporting medium which performs storage, associative retrieval and prediction for temporal sequences. The TSP has several interesting attributes: (1) it achieves any depth (or degree) constrained only by storage capacity, (2) tolerates substantial time warp, (3) supports userspecified flexible grouping of stored sequences into coarser classes at retrieval time. The TSP is also capable of preserving time extent of stored symbols, such as in a musi...
