classification of solutionsPolubarinova-Galin equationThe Polubarinova–Galin equation describes a parametric conformal map for the zero-surface-tension Hele-Shaw flow driven by injection or suction. In this paper, we classify degree three polynomial solutions to the Polubarinova–Galin equation into ...
In the case of Hermite polynomials of a single variable, the space Pk consists of all polynomials of degree k − 1 or less. We denote the Hermite polynomial of order k by tion Hek k to (x). For higher-dimensional state spaces D ⊆ Rn denote Hek(x) = Hek1 (x1)Hek2 (x2) ...
On each iteration, to find the next solution approximation, these methods require the unconstrained local minimization of a (potentially nonconvex) multivariate polynomial of degree higher than two, constructed using third-order (or higher) derivative information, and regularized by an appropriate power...
The datasets used in this study are synthesized 1-dimensional data from the UCI ML Repository [29]. comprising CVD and BC datasets with varying feature sets specific to each diagnosis. Both datasets are publicly available for research purposes and contain attributes essential for disease classificatio...

As we will see in the next section functions of higher degree sometimes give better bounds. But it does mean that no polynomial of the same degree or lower can produce a better bound. Extremality in this sense of the Levenshtein test functions was first shown by Sidelnikov [205]. We ...
A library for factorization machines and polynomial networks for classification and regression in Python. Github repository. Factorization machines and polynomial networks are machine learning models that can capture feature interaction (co-occurrence) through polynomial terms. Because feature interactions can ...
回归分析中有一类特殊情况,输出的结果是离散型的(比如识别图片里是人、猫、狗等标签的一种),此时问题称为分类(Classification)。 0x3:逼近函数方法 函数的表示是函数逼近论中的基本问题。在数学的理论研究和实际应用中经常遇到下类问题:在选定的一类函数中寻找某个函数,使它与已知函数(或观测数据)在一定意义下为...

large and diverse datasets. Our approach addresses this gap by representing an image with a polynomial function and eliminates the need for positional encodings. Therefore, to achieve a progressively higher degree of polynomial representation, we use element-wise multiplications between features and affine...
