The paper introduces VISTA, a baseline for dense multi‑label classroom coding that leverages the COPUS protocol as a video benchmark. VISTA applies MiniCPM‑V‑4.5 over sliding windows, refines predictions with an MLP head, and aggregates results onto a 2‑minute COPUS grid, achieving 80.1% macro accuracy on held‑out chemistry lectures. The authors also identify systematic failure modes and provide benchmark tooling and code on GitHub.

The paper tackles the challenge of predicting student engagement from online tutoring videos, noting that engagement is a complex, multidimensional construct influenced by behavioral, emotional, and cognitive states. By analyzing the CASED dataset, the authors highlight the difficulty posed by high inter‑person variability and subjective annotations. They propose a multimodal framework that fuses implicit spatiotemporal features from pretrained video, audio, and image encoders with structured behavioral cues such as head pose, gaze, facial action units, emotion, and wavelet‑based audio features, integrating them via a Perceiver IO bottleneck and modeling participant personalities with variational posteriors. The system employs evidential regression and spectral‑normalized Gaussian process classification heads to provide uncertainty‑aware predictions, achieving competitive performance on the CASED challenge test set while offering well‑calibrated uncertainty metrics.
