Inductive and flexible feature extraction for semi-supervised pattern categorization

作者:

Highlights:

• A flexible graph-based semi-supervised embedding is proposed.

• A kernel version of the linear semi-supervised algorithm is also proposed.

• They simultaneously estimate a non-linear embedding and its out-of-sample extension.

• Classification performance after embedding is assessed on ten benchmark datasets.

• We use KNN, SVM, and two phase test sample sparse representation as classifiers.
