comment Sum of a set normalize by total items in set
It's ok, I guess they are doing this for my good too. They want me to learn by myself through the hard way so that I will remember it by heart.

I did say that "I have a set of weighted terms, $w_1, w_2$... but I included more information now.

@BISHD I am more that happy to edit and learn and improve the answer so that it benefits everyone else too. But NO information provided to advise how/what should I improve?

I understand that, and $w$ is the individual item in $W$, what I want is to avoid using $W$ just because I want to show $\left | W \right |$ if it's possible

I am cool to get a downvote like I said this is a simple question and I am clarifying it. But for the nice guy who downvoted would you be nice again and explain why do I get a downvote?

$w$ is a set of weighted terms. Count of $w$ is total number of terms, i.e. $n$

comment Symbol for “if any”
Thanks for your useful comment, it is more for an algorithm writing than mathematical writing. What I really want to mean is, if there exist $p_i$, where $length(p_i) = length(p) + 1$ and $p$ is a strict subset of $p_i$

if $∃pi : length(pi) = length(p) + 1 ∧ p ⊏ pi ∧ support(p) = support(pi)$ ?

Probably the example I gave wasn't too good, the actual data is about 14 days, so the actual burstiness among group wasn't really significant
