【 A record of neural network entering the pit】 Difference between deep learning and neural network
There was a period of time for the neural network to enter the pit, Decide to write a blog and record what you have learned, Even a little bit, I want to see it in the future...
The content of this combing is neural network, A relationship of deep learning
I've seen some algorithms before, I tried to draw some gourds myself, But later it was found that there was some confusion about deep learning and neural networks
Write a blog and take notes：
In the field of artificial intelligence, Machine learning is one of the methods, Neural network is an algorithm in machine learning.
Neural network generally has input layer-> Hidden layer-> Output layer, Generally speaking, the hidden layer is larger than2 The neural network of is called deep neural network, Deep learning is a machine learning method with deep structure like deep neural network.
What are the advantages of deep network and shallow network?—— Deep network has stronger expression ability, More resource saving.
In my opinion, neural network is a process of fitting a function, A neural network with only one hidden layer can fit a function, But it could take a lot of neurons. The deep network can use much fewer neurons to simulate the contract like function.
