PyGTM

A python implementation of Generative Topographic Mapping.

This is beta release. For example, this project has no test as you can see.

Requirements

• numpy
• scipy
• scikit-learn

Getting Started

To install PyGTM, use pip

$ pip install -U pygtm

The pygtm package inherits scikit-learn classes.

from pygtm import GTM
from sklearn.datasets import load_iris
from sklearn.preprocessing import StandardScaler
from sklearn.pipeline import make_pipeline

iris = load_iris()
model = make_pipeline(
    StandardScaler(),
    GTM(n_components=2)
)
embedding = model.fit_transform(iris.data)
