Evaluation

You are predicting both the runway arrival time and the gate arrival time, so you have two predictions for each airplane.

Your predictions will be evaluated based on the root mean squared error (RMSE) between the predicteds and the truth:

$$ \textrm{RMSE} = \sqrt{\frac{1}{n} \sum_{i=1}^{n} (y_i - \hat{y}_i)^2}$$

We will separately compute the RMSE for gate arrival times and runway arrival times, and use a weighted average of the two:

$$ \textrm{RMSE_Final} = (0.75 \times \textrm{RMSE_Gate}) + (0.25 \times \textrm{RMSE_Runway}) $$
