For example, If I use one model to make prediction and get score 1.8 on the public lb, and I use 3 models m1, m2, m3 which are totally different in algorithms or are different in hyperparameters, but are same algorithm, to make a blending prediction based on (pred_m1 + pred_m2 + pred_m3 / 3 and get score 1.8 on the public lb. Between these two submissions, which submission I should choose so that I can probably get a higher score in the private leaderboard.</p>\n<p>Thanks!</p>",
