Remember, that in higly imbalanced data model does not learn anything as it minimises its objective function just by predicting everything to majority class. Yes Sample weight values you have assigned seems to do the right thing. What sample weight does is tweak the objective function to consider one error in predicting True class equivalent to 20 error in ...
