This competition uses
[Root Mean Squared Error](https://www.kaggle.com/wiki/RootMeanSquaredError)
as the evaluation metric.
\[ \mathrm{RMSE} = \sqrt{\frac{1}{N}\sum_{i=1}^N(p_i - a_i)^2} \]
Where:
\\(N\\) is the number of galaxies times the total number of responses
\\(p_i\\) is your predicted value
\\(a_i\\) is the actual value
