Classification and clustering. "−" represents decoy PSM, while "+" represents target PSM. The data sample represented by "□" locates far away from the decision boundary. However, the possibility of it being a correct PSM is remote since it goes too far away from other data target PSMs. The data sample represented by "" also has a small possibility to be a correct PSM since it locates near the decision boundary.
