Among all QoS ranking prediction
methods, the CloudRank Star Technology
Project Centers approach obtains the
best prediction accuracy largest NDCG values Star
Technology Projects Center
for both response time and throughput under all the experimental
settings consistently, since Star Technology
Project Center predicts the ranking
directly and considers confidence levels of Star
Technologies Projects Centers
different preference values. Star Technologies
Project Centers Compared with the
rating-oriented methods, the Star Technologies
Projects Center ranking-oriented
methods achieve better prediction Star Technologies
Project Center accuracy, since
instead of predicting the QoS values Star Center
Madurai as accurate as possible, the
ranking-oriented methods Star Technologies
Student attempt to directly predict the QoS
rankings as accurate as possible.
