1. Title: Waveform Database Generator (written in C)

2. Source: (a) Breiman,L., Friedman,J.H., Olshen,R.A., & Stone,C.J. (1984). Classification and Regression Trees. Wadsworth International Group: Belmont, California. (see pages 43-49). (b) Donor: David Aha (c) Date: 11/10/1988

3. Past Usage:

   1. CART book (above): -- Optimal Bayes classification rate: 86% accuracy -- CART decision tree algorithm: 72% -- Nearest Neighbor Algorithm: 78% -- 300 training and 5000 test instances

4. Relevant Information: -- 3 classes of waves -- 21 attributes, all of which include noise -- See the book for details (49-55, 169) -- waveform.data.Z contains 5000 instances

5. Number of Instances: chosen by user

6. Number of Attributes: -- 21 attributes with continuous values between 0 and 6

7. Attribute Information: -- Each class is generated from a combination of 2 of 3 "base" waves -- Each instance is generated f added noise (mean 0, variance 1) in each attribute -- See the book for details (49-55, 169)

8. Missing Attribute Values: none

9. Class Distribution: 33% for each of 3 classes
