Time-Aware QoS Prediction for Cloud Service Recommendation Based on Matrix Factorization

IEEE Access, 2018
Prediction of quality of service (QoS) is a critical area of research for cloud service recommendation. The disadvantage of QoS values is that they are directly related to time series of service status and network condition and thus instantly vary over ...
