|
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)
