编写要点
编写毕业论文提纲有两种方法:
一、标题式写法。即用简要的文字写成标题,把这部分的内容概括出来。这种写法简明扼要,一目了然,但只有作者自己明白。毕业论文提纲一般不能采用这种方法编写。
二、句子式写法。即以一个能表达完整意思的句子形式把该部分内容概括出来。这种写法具体而明确,别人看了也能明了,但费时费力。毕业论文的提纲编写要交与指导教师阅读,所以,要求采用这种编写方法。
3.用MATLAB做文字识别仿真
文字识别 要用神经网络。
具体参考神经网络的guide文件,关于 Character Recognition 应用:11-15Appcr1: Character RecognitionIt is often useful to have a machine perform pattern recognition. In particular, machines that can read symbols are very cost effective. A machine that reads banking checks can process many more checks than a human being in the same time. This kind of application saves time and money, and eliminates the requirement that a human perform such a repetitive task. The demonstration appcr1 shows how character recognition can be done with a backpropagation network.Problem StatementA network is to be designed and trained to recognize the 26 letters of the alphabet. An imaging system that digitizes each letter centered in the system's field of vision is available. The result is that each letter is represented as a 5 by 7 grid of Boolean values.For example, here is the letter A.Load the alphabet letter definitions and their target representations.[alphabet,targets] = prprob;However, the imaging system is not perfect, and the letters can suffer from noise.11 Applications11-16Perfect classification of ideal input vectors is required, and reasonably accurate classification of noisy vectors.The twenty-six 35-element input vectors are defined in the function prprob as a matrix of input vectors called alphabet. The target vectors are also defined in this file with a variable called targets. Each target vector is a 26-element vector with a 1 in the position of the letter it represents, and 0's everywhere else. For example, the letter A is to be represented by a 1 in the first element (as A is the first letter of the alphabet), and 0's in elements two through twenty-six.Neural NetworkThe network receives the 35 Boolean values as a 35-element input vector. It is then required to identify the letter by responding with a 26-element output vector. The 26 elements of the output vector each represent a letter. To operate correctly, the network should respond with a 1 in the position of the letter being presented to the network. All other values in the output vector should be 0.In addition, the network should be able to handle noise. In practice, the network does not receive a perfect Boolean vector as input. Specifically, the network should make as few mistakes as possible when classifying vectors with noise of mean 0 and standard deviation of 0.2 or less.ArchitectureThe neural network needs 35 inputs and 26 neurons in its output layer to identify the letters. The network is a two-layer log-sigmoid/log-sigmoid Appcr1: Character Recognition11-17network. The log-sigmoid transfer function was picked because its output range (0 to 1) is perfect for learning to output Boolean values.The hidden (first) layer has 25 neurons. This number was picked by guesswork and experience. If the network has trouble learning, then neurons can be added to this layer. If the network solves the problem well, but a smaller more efficient network is desired, fewer neurons could be tried.The network is trained to output a 1 in the correct position of the output vector and to fill the rest of the output vector with 0's. However, noisy input vectors can result in the network's not creating perfect 1's and 0's. After the network is trained the output is passed through the competitive transfer function compet. This makes sure that the output corresponding to the letter most like the noisy input vector takes on a value of 1, and all others have a value of 0. The result of this postprocessing is the output that is actually used.InitializationCreate the two-layer network with newff.net = newff(alphabet,targets,25);TrainingTo create a network that can handle noisy input vectors, it is best to train the network on both ideal and noisy vectors. To do this, the network is first trained on ideal vectors until it has a low sum squared error.Then the network is trained on 10 sets of ideal and noisy vectors. The network is trained on two copies of the noise-free alphabet at the same time as it is trained on noisy vectors. The two copies of the noise-free alphabet are used to maintain the network's ability to classify ideal input vectors.p1a111n1n235 x 110 x110 x 126 x 126 x 126 x 1Input26 x 10。
