Patent number: 11966822Abstract: Disclosed are a computer-implemented method, a system and a computer program product for feature processing. In the computer-implemented method for feature processing, two input features selected from multiple features of each sample in a sample set are projected to one resulting feature by one or more processing units based on a specified curve. The sample set is updated by replacing the two input features with the one resulting feature for each sample in the sample set by one or more processing units. The projecting and the updating for the sample set are repeated by one or more processing units until the number of features of each sample in the sample set reaches a predetermined criterion.Type: GrantFiled: September 29, 2020Date of Patent: April 23, 2024Assignee: International Business Machines CorporationInventors: Chun Lei Xu, Si Er Han, Shi Bin Liu, Yi Shao, Lei Tian, Hao Zheng, Jia Rui Wang
