In statistics, the mean absolute scaled error (MASE) is a measure of the accuracy of forecasts. It is the mean absolute error of the forecast values, divided by the mean absolute error of the in-sample one-step naive forecast.

Mason Durell Betha (born August 27, 1975), [1] better known by his stage name Mase (often stylized as Ma$e), is an American rapper. [3] . Best known for his work with Sean "Puff Daddy" Combs ' Bad Boy Records, he signed with the label in 1996 and quickly found mainstream recognition as Combs' hype man.

We could solve both of these issues by calculating either the Mean Absolute Scaled Error (MASE) or Root Mean Squared Scaled Error (RMSSE). The next tutorial will look at how we can weight the RMSSE to make it more meaningful from a business perspective.

mAP（mean Average Precision）bev下2d中心点的距离来评价，而不是像2d检测里用iou来评价mATE（Average Translation Error）中心点的2D欧式距离mASE（Average Scale Error）中心点和朝向对齐后的尺度误差，1 - IOU…

mean Average Precision (mAP): We use the well-known Average Precision metric, but define a match by considering the 2D center distance on the ground plane rather than intersection over union based affinities.
