		Neural Networks and Decision Tree Induction:  
	  Exploring the relationship between two research areas 


      A NIPS '90 workshop, 11/30/1990 or 12/1/1990,  Keystone, Colorado


			    Workshop Co-Chairs: 
		       L. Y. Pratt and S. W. Norton

    The fields of Neural Networks and Machine Learning have evolved
    separately in many ways.  However, close examination of multilayer
    perceptron learning algorithms (such as Back-Propagation) and decision
    tree induction methods (such as ID3 and CART) reveals that there is
    considerable convergence between these subfields.  They address similar
    problem classes (inductive classifier learning) and can be
    characterized by a common representational formalism of hyperplane
    decision regions.  Furthermore, topical subjects within both fields are
    related, from minimal trees and network reduction schemes to
    incremental learning.

    In this workshop, invited speakers from the Neural Network and
    Machine Learning communities will discuss their empirical and
    theoretical comparisons of the two areas, and then present work at
    the interface between these two fields which takes advantage of the
    potential for technology transfer between them.  In a discussion
    period, we'll discuss our conclusions, comparing the methods along
    the dimensions of representation, learning, and performance.  We'll
    debate the ``strong convergence hypothesis'' that these two
    research areas are really studying the same problem.
