Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intelligent artificial agent systems face issues such as brittleness and poor generalization in controlling and organizing multiple behaviors, as existing solutions fail to effectively map and manage policies within a space according to their properties.
Innovation Solution
The implementation of a policy manifold, which organizes policies using a discrete grid topology, allowing for the association of policies with coordinates and applying updates to improve the agent's performance by smoothing the policy distribution across the manifold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional control systems are used to manage agent behaviors, then the system structure is simple, but the agent exhibits brittleness and poor generalization
Solution Approach 1:
The patent segments the policy space into discrete grid cells, where each cell represents a specific policy state. This segmentation allows complex behaviors to be broken down into manageable, organized units that can be systematically controlled and generalized, resolving the contradiction between reliability and complexity by structuring the policy space in a decomposable manner.
Solution Approach 2:
The patent introduces a geometric manifold structure with multiple dimensions to organize policies. By mapping policies onto a multi-dimensional grid space, the system gains additional organizational dimensions that enable better generalization and control, transforming a flat complex structure into a structured multi-dimensional space that improves reliability without excessive complexity.
2Ease of operation
If policies are organized without a structured space, then the system is easy to operate, but policies cannot be effectively mapped and managed
Solution Approach 1:
The patent performs preliminary organization of policies by mapping them to specific coordinates in the manifold grid before execution. This pre-organization allows for efficient retrieval and management during operation, as policies are already positioned in their appropriate spatial locations based on their characteristics, improving access efficiency while maintaining a structured framework.
Solution Approach 2:
The patent creates a simplified geometric representation (copy) of the complex policy space through the manifold grid. This copied structure maintains the essential organizational relationships of policies while providing a more manageable and accessible interface for control, allowing efficient policy access without directly managing the full complexity of the original policy space.
3Adaptability or versatility
If policies are densely distributed, then more policies are available, but dissimilarities between policies are not effectively reflected
Solution Approach 1:
The patent applies local quality by assigning different spatial characteristics to different regions of the manifold grid. Policies with similar characteristics are positioned in local regions with appropriate density, while dissimilar policies are placed in distant regions. This local differentiation allows the system to maintain high policy diversity while preserving the ability to accurately reflect dissimilarities through spatial distance in the grid structure.

AI summary
A method and system comprise providing means and method for producing, modifying, and/or exploiting the structure of a policy manifold. Each of the policies at least comprises information for mapping state and/or sensory information as input to action preferences as output. One or more processing units assign each of the policies a policy coordinate on a policy manifold. The policy coordinate may in part be determined by a dissimilarity matrix or other means for organizing the coordinates of the policies on the policy manifold according to the properties of the policies and the topology of the policy manifold. The policy manifold comprises a dimensionality that is lower than a combined dimensionality of the input and the output, wherein the policy manifold at least in part determines a behavior of the intelligent artificial agent.
