FAQPage Schema

How do I reduce high-dimensional data for visualization in 2D or 3D?▼

You can use manifold learning to compute low-dimensional embeddings of high-dimensional data for 2D or 3D visualization. UMAP provides a fast, scalable method that handles datasets ranging from simple tabular data to complex feature spaces.

What is the best way to preprocess features for clustering algorithms?▼

The best way to preprocess features for clustering is to compute low-dimensional embeddings that preserve the manifold structure of your high-dimensional data. UMAP acts as a preprocessing step to generate these embeddings, making clustering algorithms more effective.

Does dimensionality reduction work with scikit-learn pipelines?▼

Yes, this manifold learning approach is fully compatible with scikit-learn pipelines for preprocessing and model building. It supports standard transform and inverse_transform capabilities, allowing seamless integration into existing machine learning workflows.

Can I use supervised learning to guide manifold learning embeddings?▼

Yes, you can use supervised or semi-supervised embedding to incorporate labels and guide the structure of the low-dimensional embeddings. This aligns the manifold learning output with specific downstream machine learning tasks.

How do I tune parameters for manifold learning on large datasets?▼

Parameter tuning for manifold learning involves adjusting settings to balance local and global structure preservation in your embeddings. This approach satisfies parameter tuning requirements while maintaining fast, scalable performance on large datasets.

When should I not use UMAP for dimensionality reduction?▼

You should not use this approach if your dataset requires strictly linear transformations or if exact feature interpretability is critical. It is designed for non-linear manifold learning rather than preserving linear variance in high-dimensional data.
