Roadheader – A comprehensive review - ScienceDirect

2020-1-1  Ebrahimabadi et al. (2015) suggested a Neural network based cutting performance (ICR) of a medium duty roadheader in the Tabas coal mine which includes the multi-layer perceptron (MLP) and Kohonen self-organizing feature map (KSOFM). They stated that the MLP predicts more reliably while KSOFM is an efficient way to understand system behaviour.
