Detailed explanation-1: -In general, it is based on combining two different machine learning techniques. For example, a hybrid classification model can be composed of one unsupervised learner (or cluster) to pre-process the training data and one supervised learner (or classifier) to learn the clustering result or vice versa [18].
Detailed explanation-2: -The algorithm constitutes three machine learning hybrid models: GWO-ET, GWO-AdaBoost, and GWO-GBM.
Detailed explanation-3: -Hybrid teaching mode is a new trend under the Education Informatization environment, which combines the advantages of educators’ supervision offline and learners’ self-regulated learning online. Capturing learners’ learning behavior data becomes easy both from the traditional classroom and online platform.
