T-sne for feature visualization
WebJan 14, 2024 · t-distributed stochastic neighbourhood embedding (t-SNE): t-SNE is also a unsupervised non-linear dimensionality reduction and data visualization technique. The math behind t-SNE is quite complex but the idea is simple. It embeds the points from a higher dimension to a lower dimension trying to preserve the neighborhood of that point.

WebModular polyketide synthases (PKSs) are polymerases that employ α-carboxyacyl-CoAs as extender substrates. This enzyme family contains several catalytic modules, where each module is responsible for a single round of polyketide chain extension. Although PKS modules typically use malonyl-CoA or methylmalonyl-CoA for chain elongation, many … WebAs in Problem 1, we recommend using PCA before running T-SNE or clustering algorithms, for quality and computational reasons. 1.
