density function in statistics

This presentation is an article on the science published by Alex and Alessandro in 2014 [13], the basic idea of the article is simple, but its clustering effect is both spectral clustering (spectral clustering) [11,14,15] And K-means characteristics,

In the last chapter, we studied the parameter estimation methods of PDF, which mainly have the maximum likelihood estimation and Bayesian estimation, they mainly estimate the parameters of the PDF with definite form, and in reality, we can't know

1: For N results in one experiment, if a real-value single-value function is matched for each result, the corresponding value is called a random variable. The mathematical definition is S = {e}. E is a sample in the sample space, and X = x (e) is
