Define the GB regressor
You'll now revisit the Bike Sharing Demand dataset that was introduced in the previous chapter. Recall that your task is to predict the bike rental demand using historical weather data from the Capital Bikeshare program in Washington, D.C.. For this purpose, you'll be using a gradient boosting regressor.
As a first step, you'll start by instantiating a gradient boosting regressor which you will train in the next exercise.
