Classification of Alzheimer's Disease, Mild Cognitive Impairment, and Cognitively Unimpaired Individuals Using Multi feature Kernel Discriminant Dictionary Learning

Front Comput Neurosci
PMCID: 5767247
PMID: 29375356
DOI: 10.3389/fncom.2017.00117

[…] noted as:The convex problems in Equation (12) can be efficiently solved by plenty of tools such as the L1-magic software package (Candes and Romberg, ), the GPSR package (Figueiredo et al., ) and the L1-homotopy package (Asif and Romberg, ).Finally, the identification of the test sample y can be employed using Equation (5) as follows:where the {·}l represents the l-th element in the brace.As it is […]


Single Sample Face Recognition Based on Intra Class Differences in a Variation Model

PMCID: 4327065
PMID: 25580904
DOI: 10.3390/s150101071

[…] , MIT database [] and FEI database []. Our approach is compared with several other algorithms including the SRC [] and SSRC [] under the same conditions whereby all methods are optimized by using the L1-Homotopy [,] algorithm with the regularization parameter λ =0.005. All experiments are done on a PC with an Intel i7 2600 CPU and 16 G RAM using a single thread. The implementation of all methods i […]
