01 machine learning related regulations

Machine learning is to let the machine find a function （Machine Learning ≈ Looking for Function）

A key technology in machine learning is deep learning , The function involved in deep learning is neural network .
Neural network like There can be all kinds of Input , For example, it can be vector vector ;Matrix matrix e.g.,image;Sequence Sequence e.g., voice , translate , A sound sequence number , In a word , A piece of writing .
There can also be various Output , For example, it can be a numerical value , The value here is called regression; It can be a category （ That is to say, the machine is provided with several options to choose ）, This is called classification classification; You can let the machine write a sentence .
