  • Sparse-matrix vector multiplication is an important computational kernel in many iterative linear solvers (see 1, for example).
  • kernel routine
  • DGEMM and kernel
  • kernel and neighborhood

So kernel, kernel function, extra life knowledge, kernel function.

Examples

  • We used the quartic kernel as our weighting scheme in this study.

    Academic text (2012)
  • Here, we describe the implementation and performance of two key BLAS-1 kernels: the DAXPY and DDOT routines.

    Academic text (1994)
  • You have to declare the kernel function to be global.

  • So this shows that the kernel is closed under inverses.

  • Set H equal to the kernel of Phi.

  • We discuss the implementation of the three kernel routines later in Section 3.

    Academic text (2000)
  • Sparse-matrix vector multiplication is an important kernel that often runs inefficiently on superscalar RISC processors.

    Academic text (1997)
  • In machine learning, the kernel function helps to determine the similarity between different datasets.

  • The model's accuracy improved significantly after using a nonlinear kernel in the calculations.

  • Researchers often rely on optimization techniques to select the appropriate kernel for their algorithms.

Etymology

The word kernel in math and machine learning keeps the same image: a kernel is like the 'core' or 'seed' rule that decides how similar two things are, so the name shows it is the central part that controls the comparison.
