WebJun 30, 2024 · t-SNE (t-Distributed Stochastic Neighbor Embedding) is an unsupervised, non-parametric method for dimensionality reduction developed by Laurens van der Maaten and Geoffrey Hinton in 2008. ‘Non-parametric’ because it doesn’t construct an explicit function that maps high dimensional points to a low dimensional space. 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 …
