past.Utils.svm_annotation(ref_mtx, ref_anno, target_mtx)

Use SVM with radial basis function kernel as classifier to train on the reference dataset and annotate the target dataset.

Parameters:

  • ref_mtx – feature matrix of reference dataset, usually referring to latent embedding of PAST

  • ref_anno – the annotation of reference dataset

  • target_mtx – feature matrix of target dataset in the same latent space with that of reference dataset

Returns:

the annotation of target dataset

Return type:

numpy.ndarray
