Methods, architecture, and apparatus for implementing machine intelligence and hierarchical memory systems
First Claim
1. A computer-based memory system comprising:
- a first lower level processing unit receiving a first portion of an input data and generating a first output representing first probabilities that sequences of patterns in the first portion of the input data correspond to first learned sequences of patterns, the first learned sequences of patterns including a first level of structures;
a second lower level processing unit receiving a second portion of the input data and generating a second output representing second probabilities that sequences of patterns in the second portion of the input data correspond to second learned sequences of patterns, the second learned sequences of patterns including the first level of structures; and
an upper level processing unit associated with the first and second lower level processing units, the upper level processing unit generates a prediction by determining whether sequences of combinations of the first output and the second output correspond to third learned sequences of patterns, wherein the third learned sequences of patterns include a second level of structures, and wherein the prediction is indicative of subsequent patterns to be received at the first and second lower level processing units or a subsequent combination of the first output and the second output to be received at the upper level processing unit.

Abstract
Sophisticated memory systems and intelligent machines may be constructed by creating an active memory system with a hierarchical architecture. Specifically, a system may comprise a plurality of individual cortical processing units arranged into a hierarchical structure. Each individual cortical processing unit receives a sequence of patterns as input. Each cortical processing unit processes the received input sequence of patterns using a memory containing previously encountered sequences with structure and outputs another pattern. As several input sequences are processed by a cortical processing unit, it will therefore generate a sequence of patterns on its output. The sequence of patterns on its output may be passed as an input to one or more cortical processing units in next higher layer of the hierarchy. A lowest layer of cortical processing units may receive sensory input from the outside world. The sensory input also comprises a sequence of patterns.
