Abstract
With significant increase in popularity of online education, need for educators to get to know about learning experiences of students and to provide feedback to students has also been increasing. In this paper, we propose an HMM-LSTM based hybrid solution to model and predict online learning activities of students using online learning management systems (LMS) or platforms and provide real-time feedback to students. Our solution is a smart classifier empowered by and based on the Markov-Chain (MC) approach, specifically a Hidden Markov Model (HMM), with the Long Short-Term Memory (LSTM) neural network. The novelty is in the use and treatment of hidden data and metrics to raise flags that indicate outlier online student behavior based on historical data from the same online session and other sessions in the past. We propose a design of a system in which we utilize HMM and LSTM, and the LSTM component of the model is ‘advised’ by the HMM probability used in the metrics that drive the outlier detection process. The system relies on the LSTM prediction to perform early detection of patterns.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
