Origin: The human visual cortex of the MeowIn the 1958, a group of wonderful neuroscientists inserted electrodes into the cat's brain to observe the activity of the visual cortex. and infer that the biological vision system starts from a small part of the object, After layers of abstraction, it is finally put together into a processing center to reduce the suspicious nature of object judgment. This approach runs counter to BP's network.The BP network thinks that every neuron in the brain has to

Introducing neural networks in normal language(Neural Networks in Plain 中文版)
Because we do not have a good understanding of the brain, we often try to use the latest technology as a model to explain it. When I was a child, we all beli
AboutNeural networks is one of the most beautiful programming paradigms ever invented. In the conventional approach to programming, we'll tell the computer, "What to do," breaking big problems up into many small, PR Ecisely defined tasks that the computer can easily perform. By contrast, in a neural network we don't tell the computer what the solve our problem. Instead, it learns from observational data, fi
Recurrent neural Networks Tutorial, part 1–introduction to RnnsRecurrent neural Networks (Rnns) is popular models that has shown great promise in many NLP tasks. But despite their recent popularity I ' ve only found a limited number of resources which throughly explain how Rnns work, an D how to implement them. That's
convolutional Neural Network (convolutional neural network,cnn), weighted sharing (weight sharing) network structure reduces the complexity of the model and reduces the number of weights, which is the hotspot of speech analysis and image recognition. No artificial feature extraction, data reconstruction, direct image input, automatic extraction of features, translation, scaling, tilt and other picture defor
Application examples of RNN--a language model based on RNN
Now, let's introduce a model based on the RNN language. We first input the word into the recurrent neural network, each input word, the recurrent neural network output so far, the next most likely word. For example, when we enter in turn:

How the reverse propagation algorithm works
In the previous article, we saw how neural networks learn through gradient descent algorithms to change weights and biases. However, before we discussed how to calculate the gradient of the cost function, this is a great pity. In this article, we will introduce a fast computational gradient algorithm called reverse propagation.

The stochastic neural networks to be explained in this paper: Simulated annealing (simulated annealing) and Boltzmann machines (Boltzmann machine) are capable of "mountain climbing" by certain probability to ensure that the search falls into local optimum. The comparison of this image can be see:There are two main differences between random
Next.
The previous two articles explained that neural networks are a black box with a small sphere (neuron) connected one by one. By changing the connection mode and parameters of neurons, you can implement a compliant neural network. Next we will give an example of a BP neural network to deepen our understanding.

A recurrent neural network (RNN) is a class of neural networks that includes weighted connections within a layer (compared With traditional Feed-forward networks, where connects feeds only to subsequent layers). Because Rnns include loops, they can store information while processing new input. This memory makes them id
layer of the network consists of multiple feature mappings, each of which is mapped to a plane, and the weights of all neurons in the plane are equal. Each feature extraction layer (c-layer) in CNN is followed by a feature mapping layer (s-layer), a unique two-time feature extraction structure that enables CNN to have high distortion tolerance for input samples.According to Figure 1, the first input image through and 3 convolution cores (filters) and offset items for convolution, the C1 layer p
