Binary spatter-coding of ordered K-tuples

Abstract

Information with structure is traditionally organized into records with fields. For example, a medical record consisting of name, sex, age, and weight might look like (Joe, male, 66, 77). What 77 stands for is determined by its location in the record, so that this is an example of local representation. The brain's wiring, and robustness under local damage, speak for the importance of distributed representations. The Holographic Reduced Representation (HRR) of Plate is a prime example based on real or complex vectors. This paper describes how spatter coding leads to binary HRRs, and how the fields of a record are encoded into a long binary word without fields and how they are extracted from such a word.
