Discovering learning behavior patterns while using Massive Open Online Courses (MOOCs) or e-learning platform education is being one of the substantial aspects in the plethora of past studies. In this study, we predict the taxonomy of learner behaviors by using the data of Junyi Academy, an e-learning platform similar to Khan Academy. We evaluate the dataset of first 2,000 unique learners and applying machine learning algorithms, i.e., Logistic Regression, and Neural Network (NNET) to predict the status of learners’ behavior. Our result shows that NNET autotuned is high accuracy champion predictive model as compared to Logistic Regression and NNET manually tuned hyperparameters models. The accuracy we measured based on Kolmogorov-Smirnov (KS) statistic for VALIDATION partition dataset. Furthermore, our model allows teachers to track or predict behavioral changes of the individual student and reveal insights into the content of the course material. It will also assist teachers in getting an early prediction of behaviors before finishing the course or skill, which is constructive and valuable for sustainable education or educational sustainability.
A new approach to the problem of part recognition is proposed by using maximum mutual information. The method applies entropy to measure image feature, combined with color information and local shape information, and uses mutual information as a new matching criterion between the images for image recognition. This method solves the problem that histogram algorithm can not represent the spatial information. This method not only has the feature of translation invariant, but also avoids image segmentation which may lead to a complex calculation, so it can be realized easily. The result shows that proposed approach is accuracy, stability, and reliability in the processing of machine part image recognition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
