Preferred term
Newton’s method
Definition
- An algorithm used to find the minimum or maximum of a real-valued function in order to solve optimization problems, especially in the training of machine learning models.
Broader concept
Synonym(s)
- Newton–Raphson method
Example
- While the log-likelihood function for ME models in (2) is twice differentiable for large scale problems the evaluation of the Hessian matrix is computationally impractical and Newton's method is not competitive with iterative scaling or first order methods. (Malouf, 2002)
