Alternating least squares (ALS) has been proved to be an effective solver of matrix factorization for recommender systems. To speedup factorizing performance, various parallel ALS solvers have been proposed to leverage modern multi-core CPUs and many-core GPUs/MICs. Existing implementations are limited in either speed or portability (constrained to certain platforms). In this paper, we present an...
Face recognition plays a fairly vital role in human computer inter-action. Eigenface algorithm is one representative approach that projects face images onto a low dimensional feature space using principal components analysis (PCA) to choose the maximal total scatter across all classes. However, due to the linear combination of original samples, eigenfaces may be difficult to interpret and explain...
The performance of I/O operations on HPC systems is a bottleneck in many parallel applications. The MPI Forum defined the MPI-IO programming interface for parallel I/O as part of the MPI-2 standard. With MPIIO, parallel applications can overcome the performance and portability limitations of existing parallel I/O interfaces. MPIIO performance analysis and tuning are important for parallel software...
Inspired by the cellular differentiation mechanism of organisms, combined with the theory of artificial life and swarm intelligence, a new biomimetic optimization algorithm, cellular differentiation optimization algorithm (CDOA), is proposed in this paper. A certain number of cells are randomly distributed in the search space to find the optimal solution by activating their differential behaviors...
