solving the above-mentioned challenging scenario. Thus, we directly project a nonfrontal view test image onto the space of frontalview harmonic basis images. The impact of some empirical factors due to the projection is embedded in a sparse warping matrix;for most cases, we show that the recognit[r]

2.2 IdentificationThe idiomaticity property of MWEs makes themboth crucial for Natural Language Processing appli-cations and difficult to predict. Their actual iden-tification in texts is therefore fundamental. Thereare different ways for achieving this objective. Thesimpler approach is lexicon-[r]

By comparison, we also evaluated the magnitude of theinitial eigenvectors for the eigenface method when using theline-fit method described in Section 5. The cumulative eigen-values computed by using the β axis as the new image planeare shown in Ta ble 3 and exhibit a similar increase in in-for[r]
