There is a subtle difference between model selection and hyperparameter tuning. Model selection can include not just tuning the hyperparameters for a particular family of models (e.g., the depth of a decision tree); it can also include choosing between different model families (e.g., should ...
Take your GBM models to the next level with hyperparameter tuning. Find out how to optimize the bias-variance trade-off in gradient boosting algorithms.

Then Random Decision Forest classifier model are optimized with the help of the Bayesian Optimization algorithm to obtain optimal hyper tuning parameters. By this, the accurate classification of breast cancer is successfully achieved. Then the efficiency of the proposed system is executed in python. ...
“N_estimators”: The number of decision trees in the forest. The default number of estimators in Scikit-Learn is 10. “Min_samples_leaf”: The minimum number of samples required to be at the leaf node of each tree. The default value is 1 in Scikit-Learn. ...
