hi everyone hope you all are doing fine .
i am working on my thesis . i apply 4 feature selection techniques such as weight by information gain ,weight by information gain ratio ,weight by Gini index ,weight by Chi sqaure .
And Every technique rank, feature in different order .
what should i do now , how i figure out the best feature from these so that i have to apply my algorithm to find result .\
waiting for your reply
thanks

If you want to have average of them for each features, you can take a look at the sample process called "Predictive Maintenance"
and especially to the "step 2" of this process : The subprocess called "determine influence factors".
Hope this helps,

because individually information gain ratio has rank different feature then information gain gini index and chi sqaure
