WebJun 15, 2024 · Model.if_then links two linear constraints left-to-right. If the first one becomes satisfied, the second will be satisfied too. In your case , I understand that in k2-k1>8 there are no decision variables involved. SO this is purely data-dependent, known at model build time. WebHere we will give an example using Python, but the same general idea generalizes to other platforms. Suppose the following code fits your model without monotonicity constraints model_no_constraints = xgb.train(params, dtrain, num_boost_round = 1000, evals = evallist, early_stopping_rounds = 10)
