F1 scores are lower than accuracy measures as they embed precision and recall into their computation. As a rule of thumb, the weighted average of F1 should be used to compare classifier models, not global accuracy. F1 Score = 2*(Recall * Precision) / (Recall + Precision) https://zhuanlan...

solving SER tasks. In particular, they are general enough to work in a real-world application context correctly. Since the results can only be considered as a starting point for further extensions, modification and improvements of the proposed approach can result in even better and...
To solve this problem, LIME was used in the test model. The method of explanation should be applicable to all ML models. We use this as an explanation that is model-agnostic along with the individual predictions, and the model should be explainable in its entirety, i.e., a global ...
To not make it longer, you can refer to Machine Learning with Tree-Based Models in Python and Machine Learning with Tree-Based Models in R. From these courses, you will learn how to use both Python and R to implement tree-based models. Emerging Classification Algorithms and Techniques As ...
