F1 score sort of maintains a balance between the precision and recall for your classifier.

When you had predicted India to win the Cricket World Cup, and it won. This gives us a lot more information than just the accuracy of the model. You will be the one doing marketing research and deciding what threshold value matches the industry standard. The confusion matrix not only allows the calculation of the accuracy of a classifier, be it the global or the class-wise accuracy, but also helps compute other important metrics that developers often use to evaluate their models. A confusion matrix is a simple table that is used to evaluate the performance of a machine-learning model. Along with classification accuracy, it also enables the computation of metrics like precision, recall (or sensitivity), and f1-score, both at the class-wise and global levels, which allows ML engineers to identify where the model needs to improve and take appropriate corrective measures. Every row of the matrix will correspond with a predicted class and every column will be linked to an actual class. But what will make your analysis stand out? Confusion Matrix As an MBA, this part is crucial ! The correct values will be in a diagonal line. Further, once you know what is confusion matrix, you can derive so many insights from your model. A confusion matrix is a table that is used to evaluate the performance of a classification model by comparing predicted values against actual values. It can be applied to binary classification as well as for multi-class classification problems. Nepali Meaning: , , not exempt from tax; the gift will be subject to taxation / a person who owes allegiance to that nation / Placed or situated under / a person who is ruled by the head of a country. The correct values will be in a diagonal line.
