Abstract
This tool trains a three-layered network of sigmoidal units using back-propagation to classify fish according to their lengths as shown below.
FIGURE 9.1 is a flow diagram illustrating a procedure for classification of fishes. In this case the fish species to be classified are salmon and trout. (Diagram after Duda et al. 2001; drawings courtesy of Bob Hines, U.S. Fish and Wildlife Service.)
FIGURE 9.2 models a three-layered, feedforward network used to classify fish by length There is 1 input unit x, 12 hidden units yi, and 3 output units z1, z2, and z3. The hidden, input, and output units are indexed by i (i= 1,.. .,12), j (j = 1), and k (k = 1,2,3), respectively. The input unit projects to the hidden units over the weights in matrix V (with elements vij). In this case, in which there is only one input unit, V is a column vector. The hidden units project to the output units over the weights in matrix U (with elements uki). The units are sigmoidal (see Chaper 6).
This tool is built from the MATLAB scripts for Tutorial on Neural Systems Modeling by Thomas J. Anastasio.
