Architecture of the ANN model constructed from FTIR spectra of B. cereus group member species. The model outcomes the B. cereus group in six different subgroups for the discrimination of non-emetic type B. cereus, emetic type B. cereus, B. thuringiensis and B. weihenstephanensis, B. mycoides, B. cytotoxicus. W and b refer to the network’s adjustable parameters which are weight matrices and bias vectors. Once the network is trained, its bias and weight values formed into a vector. The single vector is then redivided into the original biases and weights.
