A Hierarchical Multi-Factor (HMF) model organizes aggregation factors hierarchically in trees, providing clear and concise explanations through natural language summaries and visualizations to help users understand AI decisions, using a hybrid AI architecture that combines learning, problem-solving, and cognitive modeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reinforcement learning agents learn complex policies to optimize performance in complex environments, then agent capability and performance are improved, but explainability and user understanding deteriorate
Solution Approach 1:
The patent segments the complex policy into hierarchical levels (high-level goals and low-level actions) and decomposes reward signals into multiple factors (e.g., safety, efficiency, user preference). This segmentation allows the system to maintain complex decision-making capabilities while providing structured explanations at different levels of abstraction, directly resolving the contradiction between agent capability and explainability.
Solution Approach 2:
The patent introduces an intermediary explanation generation module that translates internal agent states and reward computations into human-understandable narratives. This intermediary layer bridges the gap between the complex internal reasoning processes and user comprehension, enabling users to understand agent decisions without sacrificing the agent's sophisticated policy learning.
2Adaptability or versatility
If agents consider multiple interacting factors in decision-making, then decision quality and adaptability are improved, but complexity of understanding and assessment deteriorates
Solution Approach 1:
The patent segments the multi-factor decision-making process into distinct reward factors (safety, efficiency, user preference) and hierarchical levels. Each factor can be independently analyzed and explained, making the overall complex decision process more manageable and understandable while preserving the ability to consider multiple interacting factors simultaneously.
Solution Approach 2:
The patent adds a new dimension of explanation by projecting the complex multi-factor decision space into a hierarchical structure with high-level goals and low-level actions. This dimensional transformation allows users to understand the trade-offs between multiple factors without being overwhelmed by the full complexity of the decision-making process.
3Adaptability or versatility
If agents generalize from previous experiences to handle new situations, then adaptability is improved, but predictability and consistency of behavior deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where the agent continuously monitors the outcomes of its actions and adjusts its policy accordingly. The reward decomposition into multiple factors provides structured feedback about which generalizations are successful and which lead to unexpected outcomes, enabling the agent to refine its behavior and improve predictability while maintaining adaptability.
Solution Approach 2:
The patent makes the agent's decision-making process dynamic by allowing it to adapt its generalization strategy based on the situation. The hierarchical structure enables the agent to use high-level generalizations when confident and fall back to more specific rule-based reasoning when uncertainty arises, balancing adaptability with predictable and consistent behavior.
Data Source
AI summary
A system and method for selection and explanation of solutions is provided. A hierarchy of aggregation factors is maintained for evaluating at least a partial solution. Competing solutions are generated and each solution includes at least a partial solution. Scores are calculated for each of the aggregation factors for each competing solution. A total evaluation score is calculated for each competing solution based on the scores for at least one of the aggregation factors. The competing solution with the best evaluation score is selected and a gist is generated. The gist is a narrative comparing the selected solution with the non-selected solutions based on the at least one aggregation factor. The gist is provided to a user as a rationale for selection of the solution.
