Title:
FINITE FLOW PATTERN WORD REPRESENTATION DEVICE, WORD REPRESENTATION METHOD, AND PROGRAM, STRUCTURE SHAPE LEARNING METHOD, AND STRUCTURE DESIGNING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/019883
Kind Code:
A1
Abstract:
This word representation device is provided with a storage unit and a word representation generating unit, wherein: the storage unit stores, in relation to a plurality of streamline structures forming a flow pattern, a correspondence relationship between each streamline structure and a letter relating thereto; the word representation generating unit is provided with a root determining means, a tree representation forming means, and a COT representation generating means; the root determining means determines the root of a given flow pattern; the tree representation forming means repeatedly executes processing, sequentially from the innermost portion of a given flow pattern until the root is reached, to extract the streamline structure of the given flow pattern, assign a letter to the extracted streamline structure on the basis of the correspondence relationship stored in the storage unit, and delete the extracted streamline structure, thereby forming a tree representation of the given flow pattern; and the COT representation generating means generates a word representation of the given flow pattern by converting the tree representation formed by the tree representation forming means into a COT representation. Further, a trained AI is caused to calculate the structure shape that causes a desired flow pattern to form at the periphery thereof.
