Timeline

The competition is over.

The goal of this competition is to predict the average current of 33 thermal power lines per hour of the mission's fourth Martian year (2014-04-14 to 2016-03-01).

Prediction file

For the prediction, we ask you to provide the average current (NPWD) in each of the 33 thermal power lines during the fourth year. The format of your submitted file must be a CSV file with the following columns:

The data download contains a sample prediction file named power-prediction-sample-2014-04-14_2016-03-01.csv which shows the format.

Note that for a valid submission, the file must contain 34 columns and 16488 lines of data plus one header line. The timestamps and column headers must be the same as in the sample prediction file. The submission system will inform you of any problems in your submission file (size, Inf, NaN...) and will not accept invalid files.

Evaluation

Each submission file will be evaluated against the fourth Martian year's actual average electric current data using the Root Mean Square Error (RMSE) measure.

$$\epsilon = \sqrt{\frac{1}{N M} \sum{(c_{ij} - r_{ij})^2}}$$

For the public leaderboard your data will be tested only on a portion of the fourth year's data. The final leaderboard may thus vary slightly.
