The evaluation metric for this competition is [RMSE]("https://www.statisticshowto.datasciencecentral.com/rmse/), Root Mean Square Error. 

RMSE is defined as : 
![RMSE = \sqrt{MSE} = \sqrt{\dfrac{1}{m}\sum_{i=1}^m\left(y_i-h_w(x_i)\right)^2}](https://drive.google.com/thumbnail?id=1a1YhMSdz5TlB6CShdIWT2nHhlxluThF5&sz=w700-h130)

where, there are m samples, yi is the true/known target label for the ith sample, and hw(xi) is the predicted target for the input sample xi.
