hyperparameter

hyper- +‎ parameter

hyperparameter (plural hyperparameters)

1. (Bayesian statistics) A parameter of a prior (as distinguished from inferred parameters of the model for the underlying system under analysis).

   this model has four hyperparameters

   • 2003, Gary Koop, Bayesian Econometrics, John Wiley & Sons Ltd., page 19:

     The exact interpretation of these hyperparameters becomes clearer once you have seen their role in the posterior and, hence, we defer a deeper discussion of prior elicitation until the next section.

2. (machine learning) A parameter whose value is set before the learning process begins.
   • 2016, Ian Goodfellow, Yoshua Bengio, Aaron Courville, chapter 11, in Deep Learning, MIT Press, →ISBN, page 420:

     The ideal learning algorithm just takes a dataset and outputs a function, without requiring hand tuning of hyperparameters.
