omicverse.utils.weighted_knn_trainer(train_adata, train_adata_emb, n_neighbors=50)[source]#

Trains a weighted KNN classifier on train_adata.

Arguments

train_adata: :Annotated dataset to be used to train KNN classifier with label_key as the target variable. train_adata_emb: Name of the obsm layer to be used for calculation of neighbors. If set to “X”, anndata.X will be used n_neighbors: Number of nearest neighbors in KNN classifier.

Returns

k_neighbors_transformer: KNeighborsTransformer

Parameters:

  • train_adata (AnnData)

  • train_adata_emb (str)

  • n_neighbors (int (default: 50))
