An automated modular fixture design system has been developed in our previous study. Since dedicated fixtures are commonly used in mass production, in this research, a technique of automated dedicated fixture configuration design is studied with predefined fixture component types. The design methodology is divided into two stages: basic design and detail(More)
This paper took a research about the small size sample problem of the discriminant locality preserving projections method, and proposed the discriminant locality preserving projections method based on neighborhood maximum margin (NMMDLPP). Firstly, the training sample structured a weighted of K-nearest neighbor graph, and gave the weight parameter to each(More)
According to the error approximation problem the sparse preserving projections (SPP) reconstruct the original sample. This paper proposes the algorithms based on orthogonal sparse preserving projections of kernel. In order to get sparse representation coefficients that contain more identification information by kernel method, it mapped samples to(More)
