The original perceptron could not solve the XOR function
The original perceptron was designed in the 1950s and improved in the late 1970s. The original perceptron contained one neuron that could not solve the XOR function.
An XOR function means that you have to choose an exclusive OR (XOR).
This can be difficult to grasp, as we're not used to thinking about the way in which we use or in our everyday lives. In truth, we use or interchangeably as either inclusive or exclusive all of the time. Take this simple example:
If a friend were to come and visit me, I may ask them, "Would you like tea or coffee?" This is basically the offer of tea XOR coffee; I would not expect my friend to ask for both tea and coffee! My friend will choose one or the other.
I may follow up my question with, "Would you like milk or sugar?" In this case, I would not be surprised if my friend wanted both. This is an inclusive or.
XOR, therefore, means "You...
