An example of an AI chatbot conversation about advanced masking techniques in NumPy.
How can I use advanced masking in NumPy?
You can use advanced masking in NumPy by creating boolean arrays that allow you to filter elements based on conditions.
Can you show me an example of how to create a mask?
Sure! For instance, if you have an array arr = np.array([1, 2, 3, 4, 5]), you can create a mask like this: mask = arr > 3.
What will the mask look like for that array?
The mask will be a boolean array: array([False, False, False, True, True]), indicating which elements are greater than 3.
How can I use this mask to filter the original array?
You can apply the mask directly: filtered_arr = arr[mask], which will give you array([4, 5]).
