In the context of credit scoring, ensemble methods based on decision trees, such as the random forest method, provide better classification performance than standard logistic regression models. However, logistic regression remains the benchmark in the credit risk industry mainly because the lack of ...
Decision trees and related ensemble methods like random forest are state-of-the-art tools in the field of machine learning for predictive regression and classification. However, they lack of interpretability and can be less relevant in credit scoring applications, where decision makers and regulators ...

Our course, Preprocessing for Machine Learning in Python, explores how to get your cleaned data ready for modeling. Step 3: Choosing the right model Once the data is prepared, the next step is to choose a machine learning model. There are many types of models to choose from, including ...

Develop a proprietary scoring algorithm powered by machine learning Machine learning (ML) is the best technological solution for risk scoring models. That’s already proved by a huge amount ofmachine learning use ...
In summary, our results show that each base ML model improved in performance when combined with meta-learning, i.e., the proposed stacking ensemble learning predictive model. AATD-LD Among five base ML models, ENRR appeared to have the highest prediction accuracy for all-cause mortality (...
1 represents the evolution of Google searches for explainable AI related terms. From a mathematical viewpoint, it is well known that “simple” statistical learning models, such as linear and logistic regression models, provide a high interpretability but, possibly, a limited predictive accuracy. On...
In the training process of traditional machine learning models, training sets in different domains can make the final function of the model very different. That is, when a model obtained by applying a training dataset from one domain to the same work is applied to other domains, its performance...
In fact, the reason for the success of the ensemble learning system is that each machine learning model has different errors on the data samples so that after their strategic combination, the set of models can overlap and correct each other's errors to reduce the total error. It is also ...
