This is another video from Brandon Rohrer. I add another one two posts ago called "What do Neural Networks learn? ". I add to these posts the tag "Artificial Neural Networks" to come back to see them whenever needed.
ANN are becoming quite popular and there is more a more interest to see how they work and how to apply them to the NIR spectra.
Meanwhile we try to understand as much as possible what can be considered as a black box. Thanks to Bandon for these great tutorial videos.
