Big Data Smoothing and Outlier Removal for Patent Big Data Analysis

Autor: Jun-Hyeog Choi, Sunghae Jun

Publikováno v: Journal of the Korea Society of Computer and Information. 21:77-84

In general statistical analysis, we need to make a normal assumption. If this assumption is not satisfied, we cannot expect a good result of statistical data analysis. Most of statistical methods processing the outlier and noise also need to the assu
