In the supervised learning algorithm of machine learning, our goal is to learn a stable model with good performance in all aspects, but the actual situation is often not so ideal. Sometimes we can only get multiple preferred models (weak supervised model, which performs better in some aspects). Three cobblers make Zhuge Liang. Ensemble ...

There are n closed intervals D1,..., Dn on the number axis. The interval Di is described by a pair of integers [ai, bi], which satisfies AI < Bi. It is known that the sum of the lengths of these intervals is at least 10000. Therefore, by appropriately moving these intervals, you can always make their "union& ...
