Deep Learning and Machine Learning
In: 5
I give you a brand new video game, but I don’t tell you how to play it, you have to figure it out yourself. If you are a computer then this is machine learning.
The textbook definition of machine learning is the idea of designing programs to perform a task without explicitly telling it to do it. On the mathematical side, this, very loosely speaking, boils down to solving a complex data fitting problem.
One relatively modern strategy of machine learning involve artificial neural networks (ANNs). The idea is to build a model containing many layers, with each layer made up of artificial neurons that mimics biological neurons in the brain. Deep learning is the use of ANNs that contain many layers. There’s no predetermined number of layers that determines if one is a deep network or a “shallow” network, but almost all uses of neural networks have at least three layers so everyone started using the phrase deep learning.
