weighted_rmse

Description

Calculate a weighted RMSE. Weights are based on 'time' in the case of the weights variable. (E.g. older errors weigh less). And also based on the 'direction' e.g. predicting to few used ressources is worse than predicting a few ressources used too much.

Usage

weighted_rmse(
  actual,
  predicted,
  weights = exp(-(length(actual):1)/14),
  worsenGoodExpections = 1.5
)

Arguments

actual	Real Data, vector of observations
predicted	Predicted Data, vector of observations
weights	Time based decay. Default is an exponential decay
worsenGoodExpections	Factor by how much predicting too few used ressources should be punished more.

Value

weighted RMSE
