6. Actual values
Actual values represent the true or observed values of a given variable. In the context of Rscore, actual values play a crucial role in determining the model's performance. Rscore, which stands for root mean squared error, is a metric used to evaluate the accuracy of machine learning models by measuring the difference between the predicted values and the actual values.
The connection between actual values and Rscore lies in the calculation of the mean squared error (MSE). MSE is the average of the squared differences between the predicted values and the actual values. A lower MSE indicates that the model's predictions are closer to the actual values, resulting in a better Rscore.
Understanding the relationship between actual values and Rscore is important for practitioners to effectively evaluate and compare machine learning models. By considering the actual values in the context of Rscore, practitioners can gain insights into the model's performance and make informed decisions about model selection and optimization.
