Worked examples about manifold learning using sklearn and jupyter - It's all a bit Work-In-Progress so the "should be working" notebooks are
- Manifold_S_Dataset.ipynb
- Manifold_S_Dataset_Morphed.ipynb
- Manifold_Sphere_Dataset.ipynb
- Manifold_Handwritten_Digits_Dataset.ipynb
- Manifold_tSNE_UMAP_Advanced.ipynb
- Manifold_Handwritten_Digits_Classification_WIP.ipynb

Alternatively, there are some pdf versions of related talks in the repo, the latest version being Mcubed_20181016.pdf
In the latest slides there are even more links to useful resources - most probably the full list.
- PCA - Principal Component Analysis
- GRP - Gaussian Random Projections
- SRP - Sparse Random Projections
- LLE - Locally Linear Embedding (multiple variants)
- Isomap - Isometric Feature Mapping
- MDS - Multi-Dimensional Scaling
- Spectral Embedding (Laplacian Eigenmaps)
- LTSA - Local Tangent Space Alignment
- tSNE - t-Distributed Stochastic Neighbor Embedding
- UMAP - Uniform Manifold Approximation and Projection
