Checks for NaNs in data and estimates and deletes them and then simply does: r = sqrt( sum( (data(:)-estimate(:)).^2) / numel(data) ); That's it.

After I have constructed my neural network and traind it i want to evaluate the generalisation error on the test set so I calculated yhat as the neural network outputs on the test set. now to calculate the RMSE error : root mean square error= ((sum((yhat-y(1,trset+1:16)).^2))/(16 -trset))^.5 or by this relation : root mean square error= ((sum((yhat-y(1,trset+1:16)).^2))/(16))^.5 what is the correct relation ? the first where we divide by (16-trset= 16-10=6) or the second where we divide by 16 .

(RMSE) The square root of the mean/average of the square of all of the error. The use of RMSE is very common and it makes an excellent general purpose error metric for numerical predictions. Compared to the similar Mean Absolute Error, RMSE amplifies and severely punishes large errors. $$ \textrm{RMSE} = \sqrt{\frac{1}{n} \sum_{i=1}^{n} (y_i - \hat{y}_i)^2} $$ **MATLAB code:** RMSE = sqrt(mean((y-y_pred).^2)); **R code:** RMSE <- sqrt(mean((y-y_pred)^2)) **Python:** Using [sklearn][1]: from sklearn.metrics import mean_squared_error RMSE = mean_squared_error(y, y_pred)**0.5 ## Competitions using this metric: * [Home Depot Product Search Relevance](https://www.kaggle.com/c/home-depot-product-search-relevance) [1]:http://scikit-learn.org/stable/modules/generated/sklearn.metrics.mean_squared_error.html#sklearn-metrics-mean-squared-error Last Updated: 2016-01-18 16:41 by inversion © 2016 Kaggle Inc Our Team Careers Terms Privacy Contact/Support
