Exchange interactions in (ZnMn)Se: LDA and LDA+U calculations
Physical Review B, 2003One of the remarkable properties of the II-VI diluted magnetic semiconductor (ZnMn)Se is the giant spin splitting of the valence-band states under application of the magnetic field (giant Zeeman splitting). This splitting reveals strong exchange interaction between Mn moments and semiconductor states. On the other hand, no magnetic phase transition has

LDA for Face Profile Detection
2011This paper presents a new approach to face profile classification. It was shown that the Linear Discriminant Analysis combined with the Principal Component Analysis can be used to construct an accurate face profile predictor. Proposed classifier achieves 85% accuracy in face profile prediction.

An Improvement to Matrix-Based LDA
2011The matrix-based LDA method is attracting increasing attention. Compared with classic LDA, this method can overcome the small sample size (SSS) problem. However, previous literatures neglect the fact that there are two available matrix-based LDA algorithms and usually use only one of the two algorithms to perform the experiment.
