Predicting the orbit!

You've already trained a model that approximates the orbit of the meteor approaching Earth and it's loaded for you to use.

Since you trained your model for values between -10 and 10 minutes, your model hasn't yet seen any other values for different time steps. You will now visualize how your model behaves on unseen data.

If you want to check the source code of plot_orbit, paste show_code(plot_orbit) into the console.

Hurry up, the Earth is running out of time!

Remember np.arange(x,y) produces a range of values from x to y-1. That is the [x, y) interval.

Instructions 1/2

  • 1

    Use the model's .predict() method to predict from -10 to 10 minutes.

  • 2

    Use the model's .predict() method to predict from -40 to 40 minutes.
