Installing gtmx

We assume you have Python, then install gtmx with

pip install gtmx

Import module

Simply import the module like you import other modules

import gtmx

Running examples

Here we present a simple example that you could use the GTM model to visualize the classic iris dataset.

import matplotlib.pyplot as plt
from gtmx import GTMBase
from sklearn.datasets import load_iris


iris = load_iris()
x = iris.data
y = iris.target

gtm = GTMBase(l=1)
gtm.fit(x, epoch=30)
gtm.plot_llh()
gtm.plot('mean', label=y)
gtm.plot('mode', label=y)

plt.show()
