Artificial Intelligence Neural Networks Intuition Introduction
Intuitively Understanding Machine Learning
Neural networks are famously hard to model. When I say model them, I mean explain why they come up with the prediction that they come up with. This is because they use something called automated feature selection. This means that the variables that make the prediction are automatically chosen by the neural network from the data.
Each one of these ‘features’ is called a perceptron, and they can be layered, each layer and link between representing the relationship between the features/perceptrons.
These are exactly like the associations that we have baked into our brains, and that’s the analogy to our brains that the “neural network” represents.
