Python code of Hilbert-Schmidt Independence Criterion

Hilbert-Schmidt Independence Criterion (HSIC)

Python version of the original MATLAB code of Hilbert-Schmidt Independence Criterion (HSIC).

Prerequisites

• numpy
• scipy

We tested the code using Anaconda 4.3.0 64-bit for python 2.7 on windows.

Apply on your data

Usage

Import HSIC using

from HSIC import hsic_gam

Apply HSIC on your data

testStat, thresh = hsic_gam(x, y, alph = 0.05)

Description

Input of function hsic_gam()

Argument	Description
x	Data of the first variable. (n, dim_x) numpy array.
y	Data of the second variable. (n, dim_y) numpy array.
alph	level of the test

Output of function hsic_gam()

Argument	Description
testStat	test statistic
thresh	test threshold for level alpha test

Independence test result

• If testStat < thresh, x and y are independent.
• If testStat > thresh, x and y are not independent.
