where DCGk and IDCGk are the
discounted Star Technologies Students
cumulative gain DCG Star Technologies Project
values of the Top-K services of the predicted Star
Technologies Projects ranking and
ideal ranking, respectively. The value of DCGk Star
Technology Project can be calculated
by DCGk Star Technology Projects
where reli is the QoS value of the service at position i of the
ranking. The premise of DCG is that high-quality service Star
Technology Students appearing lower
in a ranking list should be penalized as Star Technology
Student the QoS value is reduced logarithmically
proportional to the Star Tech Madurai
position of the result via dividing by Star Madurai Students
i.
