ParaDime: A Framework for Parametric Dimensionality Reduction¶
ParaDime is a modular framework for specifying and training parametric dimensionality reduction (DR) models. These models allow you to add new data points to existing low-dimensional representations of high-dimensional data. ParaDime DR models are constructed from simple building blocks (such as Relations and Relation Transforms), so that experimentation with novel DR techniques becomes easy.
Here you can see a parametric version of t-SNE 1 trained on a subset of 5000 images of handwritten digits from the MNIST dataset 2:

The rest of the 60,000 images can then be easily embedded into the same space without retraining the t-SNE:
