چکیده
The parametric representation and aerodynamic shape optimization of a three-dimensional circular-to-rectangular transition nozzle designed built using control lines distributed along the circumferential direction were investigated in this study. A surrogate model based on class/shape transformation, principal component analysis radial basis neural network was proposed with fewer design parameters for performance parameter prediction nozzle. combined Non-dominated Sorting Genetic Algorithm-II to optimize results showed that effectively achieved geometric dimensions reconstructed comparable initial model, implying they can meet needs optimal design. axial thrust coefficient lift optimized increased by approximately 0.742% 15.707%, respectively.

Explaining three-dimensional dimensionality reduction plots
Understanding three-dimensional projections created by dimensionality reduction from high-variate datasets is very challenging. In particular, classical three-dimensional scatterplots used to display such projections do not explicitly show the relations between the projected points, the viewpoint used to visualize the projection, and the original data variables. To explore and explain such rela...
متن کاملA Robust Thresholding Algorithm Framework based on Reconstruction and Dimensionality Reduction of the Three Dimensional Histogram
In this work, a robust thresholding algorithm framework based on reconstruction and dimensionality reduction of the three-dimensional (3-D) histogram is proposed with the consideration of the poor anti-noise performance in existing 3-D histogram-based segmentation methods due to the obviously wrong region division. Firstly, our method reconstructs the 3-D histogram based on the distribution of ...
متن کاملTucker Dimensionality Reduction of Three-Dimensional Arrays in Linear Time
Abstract. We consider Tucker-like approximations with an r × r × r core tensor for threedimensional n×n×n arrays in the case of r ¿ n and possibly very large n (up to 104−106). As the approximation contains only O(rn + r3) parameters, it is natural to ask if it can be computed using only a small amount of entries of the given array. A similar question for matrices (two-dimensional tensors) was ...

متن کاملData dimensionality reduction based on genetic selection of feature subsets
In the present paper, we show that a multi-classification process can be significantly enhanced by selecting an optimal set of the features used as input for the training operation. The selection of such a subset will reduce the dimensionality of the data samples and eliminate the redundancy and ambiguity introduced by some attributes. The used classifier can then operate only on the selected f...
