Air Quality Prediction of Relative Humidity - Regression
The dataset contains 9358 instances of hourly averaged responses from an array of 5 metal oxide chemical sensors embedded in an Air Quality Chemical Multisensor Device. The device was located on the field in a significantly polluted area, at road level. Data were recorded for a period of one year (March 2004 - February 2005) in an Italian city. (Dataset)

Random Forests and Polynomial Regression did a great job predicting relative humidity.
Since the default parameters already did a great job, there was no room left for improvement of the models with the help of grid search.
Based on the correlation between the variables and the target, removal of less correlated variables did not improve the accuracy of the prediction, therefore, all the variables were used in the prediction.
In addition, for Linear and Polynomial regressions not many parameters can be changed, therefore, grid search contribution to the improvement of the model score was very low.
