AI Technical Summary

Technical Problem

Existing multivariate models require prior definition of representation methods, leading to information loss and increased calculation time when handling mixed numerical and categorical data, and lack guidelines for selecting appropriate models.

Method used

An information processing apparatus and method that estimates causal relationships among variables without assuming a distribution function, allowing for the generation of discrete or continuous probability models based on variable types, enabling flexible and efficient model generation.

Benefits of technology

Enables the generation of suitable representation models for mixed data types without prior definition, reducing information loss and calculation time, and facilitating accurate causal inference.

Abstract

An information processing apparatus includes circuitry configured to estimate a causal relationship among multiple variables from multivariate data, and generate a representation model in accordance with type of variables included in the causal relationship to be a representation target, the representation model being one of a discrete probability model or a continuous probability model, wherein the circuitry is configured to generate the representation model without an initial specification of a method used to define the representation model.
