 Oct 27 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. Oct 27 comment Sum of a set normalize by total items in set I did say that "I have a set of weighted terms, $w_1, w_2$... but I included more information now. Oct 27 comment Sum of a set normalize by total items in set @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? Oct 27 comment Sum of a set normalize by total items in set Thanks very much. Oct 27 comment Sum of a set normalize by total items in set For the guys who downvoted, that's very helpful. Thanks very much. Oct 27 comment Sum of a set normalize by total items in set 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 Oct 27 comment Sum of a set normalize by total items in set 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? Oct 27 comment Sum of a set normalize by total items in set $w$ is a set of weighted terms. Count of $w$ is total number of terms, i.e. $n$ Oct 16 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 $p_i$ Oct 16 comment Symbol for “if any” if $∃pi : length(pi) = length(p) + 1 ∧ p ⊏ pi ∧ support(p) = support(pi)$ ? Dec 20 comment Help on mathematical notation and formalisation for the following description Thanks a lot :) Dec 20 comment Help on mathematical notation and formalisation for the following description Thanks Hauke, I think I know the problem. It should be $\sum_{t \in p}$, if the sum is greater, means it is more important, does that make sense to you now? Dec 20 comment Help on mathematical notation and formalisation for the following description It is an unordered tuple, I found some papers that describe this if it is an ordered tuple, e.g. Wu et al. "Deploying approaches for pattern refinement in text mining" Dec 5 comment Set notation “element-of” multiple sets Yes that sounds good, I will begin with some discrete maths reading and move on from there, thanks! Dec 5 comment Set notation “element-of” multiple sets @PatrickDaSilva: No, I am particularly interested in mathematical notation and formalisation of algorithm (please let me know if it's still too vague) Dec 5 comment Set notation “element-of” multiple sets DylanMoreland: agree, @PatrickDaSilva:thanks. A bit newbie to mathematical notation and formalisation from a coder background. I was wondering is there any books on such topics or good material to learn? Dec 5 comment Set notation “element-of” multiple sets so there is no such thing as {$e \in X,Y$} I supposed?
