Under EOC_2, when the labeled samples number is 21, IS²DP+S²DP’s outcomes of the learning set: (a) WKFDA’s projection of the learning set; (b) DP clustering result; (c) reliable samples selected and labeled by LCI. Red circle, green circle, light blue, and blue circle represent BMP2, BTR70, T72, and SLICY target samples, respectively, and represents labeled sample.
