polynomial kernel
[/ˌpɒlɪˈnoʊmiəl ˈkɜrnəl/]
nounpl: polynomial kernels
núcleo polinomial
1. A kernel function used in machine learning and support vector machines that computes the dot product of vectors in a polynomial feature space without explicitly transforming the data
The polynomial kernel with degree 3 can capture nonlinear relationships in the data more effectively than a linear kernel.
O núcleo polinomial com grau 3 pode capturar relações não-lineares nos dados de forma mais eficaz do que um núcleo linear.
2. A mathematical function defined as K(x, y) = (x·y + c)^d where d is the degree and c is a constant, commonly used in support vector machine algorithms
Researchers selected a polynomial kernel with parameters optimized through cross-validation.
Os pesquisadores selecionaram um núcleo polinomial com parâmetros otimizados por validação cruzada.
This is a specialized technical term used primarily in academic and professional contexts within machine learning, data science, and artificial intelligence fields. It is used identically in both Brazil and Portugal, and represents domain-specific terminology that has been adopted directly from English in technical communities worldwide.
