Sony patents tool to check if causal graph connections are set up right
Sony describes a software tool that helps users analyze how different factors cause changes in data. It checks the direction of connections in a causal graph to see if they are set up correctly for calculating effects. The system then highlights which specific connections need to be adjusted or confirmed by the user.
In the filing’s own words
Provided is an information processing device that performs processing related to multivariable data analysis. An information processing device includes a graph inspection unit that performs an inspection of edge direction in a causal graph when performing an intervention effect calculation from an intervention variable to a reaction variable in the causal graph, and a presentation unit that presents information regarding necessity of directing of a part of edges, specifically, edges adjacent to the intervention variable and the reaction variable on the basis of a result of the inspection of edge direction by the graph inspection unit. The graph inspection unit inspects a direction of an edge adjacent to the intervention variable and the reaction variable, and the presentation unit presents an edge that needs to be directed adjacent to the intervention variable and the reaction variable.
What exactly they claim (claim 1)
1. An information processing device comprising: a graph inspection unit that performs an inspection of edge direction in a causal graph when performing an intervention effect calculation from an intervention variable to a reaction variable in the causal graph; and a presentation unit that presents information regarding necessity of directing of a part of edges on a basis of a result of the inspection of edge direction by the graph inspection unit.
