#' Neural network parameters
#'
#' These functions generate parameters that are useful for neural network models.
#' @inheritParams Laplace
#' @details
#' * `dropout()`: The parameter dropout rate. (See `parsnip:::mlp()`).
#'
#' * `epochs()`: The number of iterations of training. (See `parsnip:::mlp()`).
#'
#' * `hidden_units()`: The number of hidden units in a network layer.
#' (See `parsnip:::mlp()`).
#'
#' * `batch_size()`: The mini-batch size for neural networks.
