Abstract
Abstract A method and system for intelligent control of external devices using a mammalian brain-like structure having three parts. The method and system include a computer-implemented neural network system which is an extension of the model-based adaptive critic design and is applicable to real-time control (e.g., robotic control) and real-time distributed control. Additional uses include data visualization, data mining, and other tasks requiring complex analysis of inter-relationships between data.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
172 words
A computer program product, comprising: a computer storage medium and a computer program code mechanism embedded in the computer storage medium for causing a computer to control an external physical device, the computer program code mechanism comprising: a first computer code device configured to create plural decision blocks, each such decision block including plural action choices, a set of exit states, and a set of post-exit states, wherein a subset of the plural decision blocks can be entered from each post-exit state; a second computer code device configured to receive inputs; a third computer code device configured to select a post-exit state of one of the plural decision blocks based on the received inputs; a fourth computer code device configured to select one of the plural decision blocks that can be entered from the selected post-exit state and that maximizes a local cost function for the selected post-exit state; and a fifth computer code device configured to produce at least one output based on the selected one of the plural decision blocks.
Claim 2
Dependent Claim
172 words
A computer program product, comprising: a computer storage medium and a computer program code mechanism embedded in the computer storage medium for causing a computer to control an external physical device, the computer program code mechanism comprising: a first computer code device configured to create plural decision blocks, each such decision block including plural action choices, a set of exit states, and a set of post-exit states, wherein a subset of the plural decision blocks can be entered from each post-exit state; a second computer code device configured to receive inputs; a third computer code device configured to select a post-exit state of one of the plural decision blocks based on the received inputs; a fourth computer code device configured to select one of the plural decision blocks that can be entered from the selected post-exit state and that maximizes a local cost function for the selected post-exit state; and a fifth computer code device configured to produce at least one output based on the selected one of the plural decision blocks.
Claim 3
Dependent Claim
28 words
The computer code device as claimed in claim 1 , wherein the post-exit states of at least one block includes states for failure and changes in goal objectives.
Claim 4
Dependent Claim
34 words
The computer code device as claimed in claim 1 , further comprising a sixth computer code device configured to update a global cost function based on the selected one of the plural decision blocks.
Claim 5
Dependent Claim
53 words
The computer code device as claimed in claim 1 , further comprising a sixth computer code device configured to update a local cost estimate corresponding to the selected one of the plural decision blocks without updating a local cost estimate of the plural decision blocks not selected by the fourth computer code device.
