Predicting using a regression model

Now that you've fit a model with the California housing data, lets see what predictions it generates on some new data. You can investigate the underlying relationship that the model has found between inputs and outputs by feeding in a range of numbers as inputs and seeing what the model predicts for each input.

A 1-D array new_inputs consisting of 100 "new" values for "MedHouseVal" (median house value) is available in your workspace along with the model you fit in the previous exercise.

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

# Generate predictions with the model using those inputs
predictions = ____

# Visualize the inputs and predicted values
plt.scatter(new_inputs, predictions, color='r', s=3)
plt.xlabel('inputs')
plt.ylabel('predictions')
plt.show()
