Abstract

An embodiment of the invention provides a method for processing data. The method includes: acquiring a training sample, initiating a Dirichlet process and a Gaussian process, acquiring a maximum Gaussian process parameter corresponding to a maximum posterior likelihood value of Gaussian process parameters and a region partition corresponding to the maximum Gaussian process parameter according to the training sample, and fitting mapping relations of unit structure geometry parameters and corresponding electromagnetic response curve cubic spline coefficients; wherein the training sample comprises the unit structure geometry parameters and the corresponding electromagnetic response curve cubic spline coefficients. During specific application, as long as the unit structure geometry parameters are known, highly close electromagnetic response curve cubic spline coefficients can be estimated, and accordingly corresponding electromagnetic response curves can be known.

Description

【Technical field】 [0001] The invention relates to the field of computers, in particular to a large-scale data processing method and device. 【Background technique】 [0002] Metamaterial technology is a cutting-edge cross-technology, and the technical fields of its design include electromagnetic, microwave, terahertz, photonics, advanced engineering design system, communication, semiconductor and other fields. Its core idea is to use complex artificial microstructure design and processing to realize artificial "atoms" to respond to electromagnetic fields or sonar. Its core theory is anamorphic optics describing electromagnetic wave trajectories and metamaterial properties. One of the core difficulties of this technology is how to model and design thousands of different artificial microstructures and arrange them reasonably to form a metamaterial device with special functions. This has brought great difficulties to modeling, calculation, theoretical analysis, design, and debu...
