%
% Comment from that web site:
%
% The goal of the Working Group on Data Modeling Benchmarks (under IEEE Neural Networks Council 
% Standards Committee) is to provide an easy access to references to modeling 
% approaches and related datasets via WWW. Hopefully this can facilitate further 
%  research and comparisons on computational data modeling approaches, including artificial 
% neural networks, fuzzy inference systems, CART, MARS, and all nonlinear regression 
% and optimization techniques. 
%
% This page is constantly under construction, but the lists of datasets/publications 
% are by no means complete. If you have new datasets/papers and would like to
% put them here, please send me an email (jang@cs.nthu.edu.tw) to let me know where 
% to link them. Any feedbacks and suggestions are also highly welcome.

% Suppose you are given data from how a human operator controls a chemical plant.
% In particular, suppose that the operator has indications of monomer concentration (u1),
% change in monomer concentration (u2), monomer flow rate (u3), some local temperatures
% in the plant (u4, u5), and with these makes decisions on how to set the set point for the 
% monomer flow rate (y).  Here, the actual value of the monomer flow rate to be put
% into the plant is controlled by a PID controller.  Below, there are 70 data pairs.
