A kind of computer based low quality classification chart is as data cleaning method
Technical field
A kind of cleaning method of the low quality classification view data based on convolutional neural networks, this method can be to from interconnection The low quality classification view data of net batch collection is effectively cleaned, so as to obtain higher-quality view data, for instructing Practice the higher disaggregated model of a discrimination, belong to artificial neural network technology field.
Background technology
Artificial neural network (Artificial Neural Network, i.e. ANN), it is artificial since being the 1980s The study hotspot that smart field rises.It is abstracted from information processing angle to human brain neuroid, and it is simple to establish certain Model, different networks is formed by different connected modes.Neutral net or class are also often directly referred to as in engineering and academia Neutral net.Neutral net is a kind of operational model, is formed by being coupled to each other between substantial amounts of node (or neuron).Each A kind of specific output function of node on behalf, referred to as excitation function (activation function).Company between each two node Connect and all represent one for the weighted value by the connection signal, referred to as weight, this memory equivalent to artificial neural network. The output of network then according to the connected mode of network, weighted value and excitation function it is different and different.And network itself is generally all Certain algorithm of nature or function are approached, it is also possible to a kind of expression of logic strategy.
Convolutional neural networks (Convolutional Neural Network, CNN) are a kind of feedforward neural networks, and One kind of artificial neural network, its artificial neuron can respond the surrounding cells in a part of coverage, for large-scale Image procossing has outstanding performance.Because its unique network structure can be effectively reduced the complexity of Feedback Neural Network, mesh Preceding convolutional neural networks have turned into the study hotspot of current speech analysis and field of image recognition.Its weights share network structure It is allowed to be more closely similar to biological neural network, reduces the complexity of network model, reduces the quantity of weights.The advantage is in network Becoming apparent of showing when being multidimensional image of input, allow input of the image directly as network, avoid tional identification Complicated feature extraction and data reconstruction processes in algorithm.Convolutional neural networks are compared to traditional neutral net, and its feature is such as Under:
