1 Algorithm Introduction XGBoost, short for eXtreme Gradient Boosting, is an ensemble learning algorithm based on Gradient Boosting Decision Trees (GBDT). It improves upon GBDT by introducing regularization terms and second-order derivative information, enhancing model performance and generalization ability. As an efficient ensemble learning algorithm, XGBoost effectively utilizes multi-core processors for parallel computing, accelerating the … Read more
When companies interview candidates, the interviewers usually include HR, team leaders, and department managers. The process can be divided into two forms. The first form is where the three interviewers interview the candidates separately. The questions may be the same or different, and each interviewer will give a conclusion based on the candidate’s performance. Finally, … Read more
