Introduction:

is paper introduces a new method for predicting the performance of a machine learning model based on the analysis of its training and validation data. The proposed approach involves using a technique called "cross-validation" to evaluate the model's accuracy and reliability. Cross-validation is a statistical method that divides the dataset into multiple subsets, allowing the model to be tested on different subsets during training. This helps to ensure that the model's predictions are more accurate and robust than those obtained from a single test set. The paper also discusses the advantages of cross-validation, including its ability to identify overfitting and underfitting issues in the model, as well as its potential to improve the generalization of the model to unseen data. Finally, the paper presents a case study that demonstrates the effectiveness of the proposed method in predicting the performance of a machine learning model
