Description: The validation procedure in the context of machine learning is a systematic method for evaluating the performance of a predictive model. This process is crucial to ensure that the model not only fits well to the training data but also generalizes adequately to unseen data. Validation involves splitting the dataset into several parts, where one part is used to train the model and another to test its performance. There are different validation techniques, such as cross-validation and holdout validation, which allow for a more robust evaluation by using multiple splits of the data. Validation helps identify issues like overfitting, where a model adapts too closely to the training data and loses generalization capability. Additionally, it provides quantitative metrics that allow for the comparison of different models and the selection of the most suitable one for a specific task. In summary, the validation procedure is an essential stage in the development of machine learning models, ensuring that they are effective and reliable in practical applications.
