Abductive Hypothesis Generation with Dynamic User Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The weighted abductive inference method disclosed in Non-Patent Literature 1 may generate hypotheses that do not align with a user's evaluation criteria, making it difficult to derive convincing hypotheses for the user.
Innovation Solution
An information processing device that generates multiple hypotheses through abductive inference, displays their elements to the user, accepts user feedback on these elements, and regenerates hypotheses based on the feedback, applying varying constraint conditions.

Engineering Contradiction Analysis
1Productivity
If weighted abductive inference is used to generate hypotheses, then the hypothesis generation process is automated and efficient, but the generated hypotheses may not align with user evaluation criteria and may not be convincing to users
Solution Approach 1:
The system accepts feedback from users on displayed hypotheses and uses this feedback to iteratively refine and regenerate hypotheses. The acceptance means receives user feedback on hypothesis elements, and the hypothesis generation means uses this feedback to adjust constraint conditions and generate improved hypotheses, creating a closed-loop system that continuously improves hypothesis quality based on user responses.
Solution Approach 2:
The constraint conditions applied during hypothesis generation are made dynamic and adaptable based on user feedback. The system adjusts constraint conditions iteratively according to user responses, transforming the static hypothesis generation process into a dynamic one that evolves to better match user expectations and evaluation criteria.
2Adaptability or versatility
If multiple hypotheses are generated and displayed to users, then the system provides more options for user evaluation, but the complexity of the system increases
Solution Approach 1:
The hypothesis generation and display process is segmented into distinct functional components: a hypothesis generation means that creates multiple hypotheses, a display means that presents them to users, and an acceptance means that collects feedback. This segmentation allows the system to handle multiple hypotheses in a structured manner without overwhelming complexity.
Solution Approach 2:
The hypothesis generation means serves multiple functions: it initially generates hypotheses based on constraint conditions, displays them through the display means, and then regenerates refined hypotheses based on user feedback. This multi-functionality reduces the need for separate specialized components, managing system complexity while providing diverse hypothesis options.

AI summary
In order to generate a hypothesis which is convincing to a user, an information processing device (1) includes: a hypothesis generation section (11) which generates, by abductive inference, a plurality of hypotheses that differ from each other; a hypothesis display section (12) which causes a display device to display a plurality of elements making up each of the plurality of hypotheses that have been generated; and an acceptance section (13) which accepts, from a user, a feedback on at least one of the plurality of elements that have been displayed. The hypothesis generation section (11) applies a constraint condition which varies depending on the feedback, and regenerates at least one hypothesis.
