Changes in version 1.1-3 NEW FEATURES o The new function combine makes predictions combining several neural networks possibly optimized with different classes. o The new function tune.hann helps to choose the hyperparameters (number of hidden neurons and slope of the activation function). o The new function hann is a wrapper for all types of neural nets. The new class "hann" has 'secondary' classes "hann1" or "hann3". There are several new methods: summary(), plot(), coef(), fitted(), str(), and labels(). o The optimized networks now include an element $fitted with the final signals, and an element $labels with the labels of the input classes. o The new function binarize helps to prepare the binary patterns from vectors or matrices of numeric values (e.g., read from image files). BUG FIXES o A bug has been fixed in the calculations of gradients of hann3() so convergence should be improved (and faster). o The internal code used to allocate new memory at each iteration: this is fixed. OTHER CHANGES o The internal code of hann3() has been optimised so it should be at least twice faster. Changes in version 1.1 (2025-08-20) o Included R_NO_REMAP in prototype_7.c. Changes in version 1.0 (2025-07-25) o Initial release on CRAN. Changes in version 0.1 o Initial release on GitHub.
