Using the Mean Absolute Percentage Error for Regression Models [PDF]

open access: yes, 2015
We study in this paper the consequences of using the Mean Absolute Percentage Error (MAPE) as a measure of quality for regression models. We show that finding the best model under the MAPE is equivalent to doing weighted Mean Absolute Error (MAE ...

Empirical analysis of IPv6 transition technologies using the IPv6 Network Evaluation Testbed [PDF]

open access: yesEAI Endorsed Transactions on Industrial Networks and Intelligent Systems, 2015
IPv6 has yet to become more than a worthy successor of IPv4, which remains, for now, the dominant Internet Protocol. This is due to the complicated transition period through which the Internet will have to go, until IPv6 will completely replace IPv4. One
