Article Introduction：Kappa is a Greek letter used to represent kappa coefficient or kappa number, which is often used in various scientific and engineering fields, especially in meteorology, statistics and machine learning. The Kappa coefficient is a very useful statistical indicator that can be used to evaluate the performance of a classification model. It not only considers the accuracy of model predictions, but also compares it with random guessing, which has good interpretability. By using the Kappa coefficient, you can better understand the classification effect of the model and make better decisions in practical applications.

Article Introduction：Kappa coefficient is a statistic that measures classification accuracy and is often used to deal with imbalanced data sets. It evaluates the model's accuracy by comparing the model's predicted results with the actual classification results, paying special attention to the model's ability to predict positive and negative examples. Kappa coefficient is an important classification performance evaluation index, especially suitable for dealing with imbalanced data sets. It can take into account different types of errors and provide a more comprehensive performance assessment.
