Using barh to plot top 10 values in Feature Selection
显示 更早的评论
Hello,
I did Feature Selection of 700 features.
I want to bar plot only the top 5 (with highest predictor rank).
Can you please help?
Thank you in advance.
[idx,scores] = fscmrmr(t_FeaturesData(:,2:700),t.score);
barh(scores(idx))
xlabel('Predictor rank')
ylabel('Predictor importance score')

My pleasure!
I did not see that part of the post earlier.
Looking through the documentation for the fscmrmr funciton (that I have no experience with), it would seem that the 5 most important predictors are given by the first 5 elements of idx, as described in the example in the documentation section Rank Predictors by Importance . That would appear to do exactly what you describe. If it does not, use maxk on the relevant variable, that most likely being ‘score’.
