Is Randomforest a good approach for (n less than p) classification problems ?

here n is the number of observations(rows)

p= number of features(variables)

and n is less than p situation

Random Forest typically would not perform well in these kind of problems. Actually, the performance starts degrading even when n & p become comparable.

I would look at ways to reduce the number of features first before applying Random Forest.

Thanks will do some variable reduction like Pricipal component analysis or some regularisation
