$(35\%)$ Suppose we have five instances at node A during the construction process of a deci$-$

sion tree. Among the five instances, $2$ instances belong to class $1,$ another instance belongs

to class $2,$ another instance belongs to class $3,$ and the last one belongs to class $4.$ Clearly,

we have a clash set of five instances at node $A.$ Please answer the following questions.

$($a$)(5\%)$ If the delete branch strategy is adopted, how do we deal with node $A?$

$($b$)(5\%)$ If the majority voting strategy is adopted, how do we deal with node $A?$

$($c$)(5\%)$ If the clash threshold is set to be $0,$ how do we deal with node A using the clash

threshold strategy?

$($d$)(5\%)$ If the clash threshold is set to be $10\%,$ how do we deal with node A using the

clash threshold strategy?

$($e$)(5\%)$ If the clash threshold is set to be $20\%,$ how do we deal with node A using the

clash threshold strategy?

$($f$)(5\%)$ If the clash threshold is set to be $30\%,$ how do we deal with node A using the

clash threshold strategy?

$($g$)(5\%)$ If the clash threshold is set to be $60\%,$ how do we deal with node A using the

clash threshold strategy?
