Homework 1\

Due: April 20
|

|
|
|
||
|
|
(10 Points) Suppose that you are trying to discretize a continuous
|
||
|
|
attribute by using the ChiMerge Algorithm. When you merge two rows
|
||
|
|
(because the $\chi^{2}$ statistic of the upper row falls below a
|
||
|
|
threshold) you must the recompute at least one $\chi^{2}$ value. Is the
|
||
|
|
new value necessarily greater than the old one?
|
||
|
|
|
||
|
|
A formal proof is not necessary. Just an intelligent discussion. You
|
||
|
|
will not lose points by giving the wrong answer, only by not being
|
||
|
|
intelligent in your discussion.
