Project description
outerspace
An interactive widget for Jupyter notebooks to explore the parameters of t-SNE or UMAP.
Installation
pip install outerspace
Additionally, if you use jupyter notebook
:
jupyter nbextension enable --py widgetsnbextension
... or for jupyter lab
:
jupyter labextension install @jupyter-widgets/jupyterlab-manager
jupyter labextension install jupyterlab_bokeh
Usage
Run t-SNE on the digits data set (see result in the image above):
from outerspace import tsne_playground
from sklearn.datasets import load_digits
digits = load_digits()
X, y = digits.data, digits.target
tsne_playground(X, y)
Show the actual digit images in a tooltip:
from outerspace import tsne_playground, array2d_to_html_img
from sklearn.datasets import load_digits
digits = load_digits()
X, y, images = digits.data, digits.target, digits.images
images = 256 - images * 16 # convert range and invert
images = images.clip(0, 255) # clip values at 255
images = images.astype('uint8') # convert to uint8
images = [array2d_to_html_img(image, resize=(32,32))
for image in images] # convert to HTML images
tsne_playground(X, y,
additional_columns=dict(images=images),
tooltips='@images{safe}') # safe = do not escape HTML
