arXiv:2606. 04408v1 Announce Type: cross Abstract: High-dimensional and incomplete (HDI) data are prevalent in many real-world big data scenarios.
A two-stage forecasting system is introduced for predicting CPU workload in private clouds. The model first forecasts customer service requests in Transactions Per Second (TPS) and then estimates future CPU usage from the TPS forecast, both stages using XGBoost within a cascaded architecture. Experiments on real private‑cloud traces show SMAPE below 7% for most applications, with the best case achieving an MAE of 0.7372 and an R² of 0.9185, and stable error accumulation over a 60‑step horizon.

QoNext is a new framework that applies Quality of Experience (QoE) principles from networking and multimedia to evaluate foundation models in a conversational setting. It identifies experiential factors that influence user experience, collects human ratings in controlled interaction scenarios, and builds a database and neural predictor to estimate user satisfaction from system parameters. The framework demonstrates the ability to decode the mechanisms of user satisfaction and predict human sentiment across varied service conditions.
