1 Introduction
Remember when I first contacted RoboCup 2 years ago, I heard from my seniors that Ann (artificial neural network), this thing can be magical, he can learn to do some problems well enough to deal with. Just like us, we can learn new knowledge by studying.
But for 2 years, I've always wanted to learn about Ann, but I haven't been successful. The ma
1 Introduction
An XOR operation is a commonly used calculation in a computer:
0 XOR 0 = 0
0 XOR 1 = 1
1 XOR 0 = 1
1 XOR 1 = 0
We can use the code in the first article to calculate this result Http://files.cnblogs.com/gpcuster/ANN1.rar (need to modify the training set), we can find that the results of learning does not satisfy us, because the single layer of neural network learning ability is limited ,
In the previous article "Artificial Neural Network (Artificial neural netwroks) Notes-Eliminate the sample order of the BP algorithm" to modify the weight of the method is called the "steepest descent method." Every time the weight of the changes are determined, the weight w
Single-layer perceptron does not solve the XOR problem
Artificial Neural Networks (Artificial neural netwroks) have also fallen into low ebb due to this problem, but the multilayer Perceptron presented later has made the artificial neur
This is an extension of the discrete single output perceptron algorithm

Artificial neural Network (Artificial neural netwroks) Notes--2.1.3 steps in the discrete multi-output perceptron training algorithm are multiple judgments, so we say it's a discrete multiple output perceptron.
Now take the formula Wij=wij+α (YJ-OJ) Xi instead of that step
introduces the latter.1958 Rosenblatt presented the Perceptron (Perceptron), which is essentially a linear classifier, 1969 Minsky and Papert wrote a book "Perceptrons", which they pointed out in the book: ① Single-layer perceptron can not achieve XOR function, ② computer ability is limited, can not deal with the long-running process of neural

Artificial neural network is a simulation of the biological nervous system. Its information processing function is determined by the input and output characteristics (activation characteristics) of the network Unit (neuron), the topology of the network (the connection mode o
The ① Artificial Neural Network (ANN) is a widely connected giant system. Neuro-scientific research shows that the main part of the human central nerve cortex is composed of 10[11]~10[12] neurons, each neuron has a 10[1]~10[5] synapse, Synapse is a junction between neurons, determining the strength and nature of the connection between neurons. This suggests that
