Every subset of a frequent itemset is also frequent. Also known as Apriori Property or Downward Closure Property, this rule essentially says that we don't need to find the count of an itemset, if all its subsets are not frequent. This is made possible because of the anti-monotone property of support measure - the support for an itemset never exceeds the support for its subsets. Stay tuned for this.
That property is called CLOSURE.
Closure
Add two positive integers and you ALWAYS have a positive integers. The positive integers are closed under addition.
;: Th. Closed under union, concatenation, and Kleene closure. ;: Th. Closed under complementation: If L is regular, then is regular. ;: Th. Intersection: .
yes, because an integer is a positive or negative, rational, whole number. when you subject integers, you still get a positive or negative, rational, whole number, which means that under the closure property of real numbers, the set of integers is closed under subtraction.
No. Closure is the property of a set with respect to an operation. You cannot have closure without a defined set and you cannot have closure without a defined operation.

In Relational algebra allows expressions to be nested, just as in arithmetic. This property is called closure.
That property is called CLOSURE.

yes, basically they stick downward but sometimes they stick upward.
It is called the property of "closure".

The closure property of addition says that if you add together any two numbers from a set, you will get another number from the same set. If the sum is not a number in the set, then the set is not closed under addition.
Closure, an identity element, inverse elements, associative property, commutative property
closure property is the sum or product of any two real numbers is also a real numbers.EXAMPLE,4 + 3 = 7 The sum is real number6 + 8 = 14add me in facebook.. lynnethurbina@yahoo.com =]
