Now we have reached a range of 47-48 % F1-Score with all 3 Boosted models. Note: We need to make sure to include a variety of models to feed a Voting Classifier to be sure that the error made by one might be resolved by the other. It’s an interesting Binary Classification problem – meaning the Target we are going to predict will have only 2 Categories – Yes ( Promoted ) or No ( Not Promoted). Since Ffill and Bfill worked well, we can assume that while Collecting data, relevant data of relevant employees with the same educational background were collected close to one another in a sequential manner. Subsample ratio of the training instances. Example: If we ask 5 of our Readers to rate this Article (out of 5): We’ll assume three of them rated it as 5 while two of them gave it a 4. F1 score is the evaluation metric for this Hackathon. Great job , Excellent and impressive and massive approach brother, you really did a great job interesting work.
