preface This program can identify the numbers 1-9. A total of 270 pictures in the training set are used for training, that is, 30 pictures for each number are used for training. Finally, in the test set, 10 pieces of each number, that is, 90 pieces, were found for accurate identification. Note this article is reproduced in:( Recognition of ...

1 operation of cell array cell in MATLAB Create a 6 * 4 array with reshape function: A = reshape(1:20,5,4)' be careful: During the use of reshape function, it should be noted that the dimension of the created array should correspond to the original quantity, otherwise the following error will be reported: 1.1 mutual conversion ...

In any Automatic speech recognition system, the first step is to extract features. In other words, we need to extract the identifiable components from the audio signal, and then throw away other messy information, such as background noise, emotion and so on. Understanding how speech is produced is very helpful for us to understand speech ...

1, Introduction to grey Wolf algorithm Grey wolf optimization algorithm (Grey Wolf Optimizer, GWO) a population intelligent optimization algorithm proposed by Mirjalili, a scholar at Griffith University in Australia, in 2014. The algorithm is an optimization search method inspired by the prey hunting activities of gray wolves. It has the chara ...

1, Introduction to particle swarm optimization 1 Introduction The group behavior of birds and fish in nature has always been the research interest of scientists. Biologist Craig Reynolds proposed a very influential bird swarm aggregation model in 19 eight 7. In his simulation, each individual follows: avoid collision with neighboring individua ...

1, Introduction 1 concept of particle swarm optimization Particle swarm optimization (PSO) is an evolutionary computing technology, which originates from the research on the predation behavior of birds. The basic idea of particle swarm optimization algorithm is to find the optimal solution through the cooperation and information sharing among ...

Batch fitting and prediction of data using MATLAB Problem introduction First, I got a set of data. The abscissa is the temperature and the ordinate is the position. The data content is the change of a variable with temperature and position, as follows: What I need to get is the specific relationship between the variable and temperature and p ...

1. Preface For the image with low original contrast, we can improve the contrast to enhance the recognition of the image, improve the visual effect of the image, convert it into a form more suitable for human and machine processing, remove useless information and improve the use value. Typical algorithms such as CT image enhancement, fog and ...

Logistic chaos scrambling, not to mention how complex, is actually very simple. Logistic function is a dynamic system derived from population statistics, and its system equation form is as follows:  X(k+1) = u * X(k) * [1 - X(k)],(k=0,1,...,n) Don't worry about how you get this equation first. If you feel uncomfortable, go to Baidu yourself. ...
