PCA (or Principal Component Analysis) is a “statistical procedure that uses orthogonal transformation to convert a set of observations of possibly correlated variables…into a set of values of linearly uncorrelated variables called principal components.” ...
only a few different approaches have been developed in this space. Moreover, there have been only a handful of systematic benchmarking studies of scRNA-seq feature selection methods7,8,9. A good feature selection algorithm is one that selects cell-type-specific (DE) genes as features...
Otherwise, it will generate new PCA and UMAP embeddings internally.Extended usage detailscytotrace2 Required input:input: Single-cell RNA-seq data, which can be an expression matrix (rows as genes, columns as cells), a filepath to a tab-separated file containing the data table, a Seurat ...
K-nearest neighbors (KNN) A simple yet effective model that classifies data points based on the labels of their nearest neighbors in the training data. Principal component analysis (PCA) Reduces data dimensionality by identifying the most significant features. It’s useful for visualization and data...

Various methods can be used to estimate the optimal number of clusters, such as the elbow method, silhouette analysis, or gap statistic. These methods evaluate clustering results for different numbers of clusters and provide insights into the optimal number based on internal or external validity ...
