Description

A Python package for Generative Topographic Mapping (GTM) Provide original version of GTM by Bishop et al. (1998) and GTM through time by Bishop et al. (1997).

Installation

$ pip install gtmx

basic GTM

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)

GTM through time

from gtmx import GTMTimeSeries
import numpy as np

x = np.ndarray(["Your time series data in shape (n_obs, sequence, dimension)"])

gtm = GTMTimeSeries()
gtm.fit(x)
gtm.plot_llh()
gtm.plot('mean')
gtm.plot('mode')
