Title:
METHOD AND DEVICE FOR GENERATING INCREMENTAL KERNEL DENSITY ESTIMATOR, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/024243
Kind Code:
A1
Abstract:
Disclosed in the present invention are a method and a device for generating an incremental kernel density estimator, and a computer readable storage medium, which are used for mining data and solve the problem in the prior art that the cost of generating a kernel density estimator is too high. Said method comprises: acquiring and storing existing data and newly added data, and storing the existing data and the newly added data into different positions; generating a first kernel density estimator according to the existing data; generating a second kernel density estimator according to the newly added data; fusing the first kernel density estimator and the second kernel density estimator, so as to update the first kernel density estimator; and generating an window width parameter of the updated first kernel density estimator, so that the updated first kernel density estimator is normally used. When the newly added data is added, the first kernel density estimator is able to be updated by simply using the second kernel density estimator, without the need to generate a new first kernel density estimator on the basis of all data, thereby reducing the cost of generating a kernel density estimator.
