CatBoostAcademicsStudent performanceIn every educational institution, predicting pupils' performance is a vital responsibility. Due to this, a variety of data mining techniques, such as clustering, classification, and regression, are applied to anticipate the learner's study behavior. By Machine Learning...

In this paper, we propose a novel approach to classify categorical data using gradient boosting decision trees, namely, CatBoost. First, we investigate the importance of the features identified by the CatBoost model. Second, we compare our approach with eight reference machine learning models at ...
The n_estimators value on the best model (automl.model) provided by FLAML does not seem to be set correctly for CatBoostClassifiers. Example code here: from flaml import AutoML from sklearn import datasets dic_data = datasets.load_iris(as_frame=True) # numpy arrays iris_data = dic_data...

In Section 2, the CatBoost algorithm, the principle of Bayesian optimization algorithm based on random forest and K-fold cross-validation, as well as the theoretical equation derived from the revised Cambridge model, and the selection of quantitative evaluation indicators are introduced, respectively. ...
