Description: Z-score analysis is an analytical method that uses Z-scores to interpret data distributions. This technique is based on normalizing data, allowing values to be comparable regardless of the original scale. The Z-score is calculated by subtracting the mean of a data set from a specific value and dividing the result by the standard deviation of the set. This transforms the data into a standard scale, where a Z-score of 0 indicates that the value is equal to the mean, while positive or negative values indicate how many standard deviations it is above or below the mean, respectively. This approach is particularly useful in data analysis, as it allows for the identification of outliers and a more effective assessment of data distribution. Additionally, Z-score analysis is fundamental in hyperparameter optimization in machine learning models, where the goal is to adjust parameters to improve model performance. By using Z-scores, researchers can evaluate the relative importance of different hyperparameters and their impact on model accuracy, thus facilitating informed decision-making in the optimization process.
