To help simplify the remainder of the article, it’s important to look at the main different types of AI. AI can be categorized into three levels based on its capabilities: Artificial Narrow Intelligence (ANI): This is the most common form of AI we interact with today. ANI is designed ...
In NumPy, slices of arrays are views to the original array. This behavior saves memory and time, since the values in the array don’t have to be copied to a new location. However, it means that changes that you make to a slice from an array will change the original array. You should...
The NumPy random choice function is a lot like this. Given an input array of numbers, numpy.random.choice willchooseone of those numbers randomly. So let’s say that we have a NumPy array of 6 integers … the numbers 1 to 6.
