Now, let's review discrete mathematics ~ By the way, I have a thorough understanding of the girl's skills. It's not a dream for the girl friend of programmers! The discrete mathematics class (csci2110) has an interesting question. Suppose there are five boys and fi

Thoughts on Discrete Mathematics and Its Application)

Discrete Mathematics and its application have a lot of content, which is difficult. If you want to learn programming, you can find a discrete mathematics with a lower difficulty but a lot of content. Second, we need to learn about the data structure and algorithms.Discrete Mathematics is very important for algorithm design. It is more difficult to provide more in-depth content. We suggest learning it step b

If the Jobbenouri test fails, the Bernoulli random variable is evaluated as 0.Maximum likelihood estimation (Maximum likelih

Simulation analysis of continuous system and discrete system

Simulink simulation analysis is mainly divided into continuous system and discrete system simulation analysis, the general simulation analysis are these two kinds of mixing, called hybrid system simulation analysis. Here are two more commonly used continuous systems and discrete system simulation analysis modules Unite Delay and Zero-order hold modulesRepresents the function of two modules, it is obvious th

Sklearn discrete AdaBoost vs Real Adaboost__sklearn

In modular learning, there are generally parametric learning_rate: Learning rate Learning Rate This is a value on [0, 1], and some of the articles say it's used to set the iteration range in the algorithm, The General Assembly leads to the fitting, the fitting means that the fitting function oscillation instability, which is intuitively understandable. For the AdaBoost combined model call Staged_predict, the predicted values for each iteration stage can be obtained. The Sklearn.metrics.zero_one_

The following code originates from http://blog.csdn.net/nuaazdh/article/details/7059630 and is slightly modified with "g++-O Bank bank.c" compiled under CentOS. Every time the system randomly generates 1, the current customer customer's counter is serviced by 2. The current customer and next customer arrival time interval, remember that these 2 points understand the entire code, the book is not very clear. The waiting time for each customer in the bank depends on the departure time of the previo

The basic concept of the graph theory of discrete mathematics

Recently in the chapter on the graph theory of discrete mathematics, here is my classification and summary of some important concepts of the graph. Describe the concept of relationships Association--used to describe the relationship between a point and an edge, which simply means that the edge is made up of those points and is associated with those points. The correlation matrix is a matrix that records the number of points in the Edge Association.

Perceptron Training algorithm----discrete single output

Perceptron is an early neural network model, presented by American scholar F.rosenblatt in 1957. Because the concept of learning was introduced for the first time in Perceptron, the learning function possessed by the human brain was simulated in a mathematical model based on symbolic processing, so it aroused a wide concern. The simple Perceptron model is still the structure of the M-P model, but it can gradually enhance the ability of the pattern division by using supervised learning to achie

"A first Course in probability"-chaper4-discrete random variable-two-item distribution

Two items distributed:Based on the most basic discrete random variable--Bernoulli random variable x, we perform n repetition experiments, the probability distribution result is so-called two-item distribution.Specifically, the probability of a successful experiment is p, and now we do n at this time Yang, set random variable x to indicate the number of successful times of n experiments, then the following distribution column is established.Regarding i

"A first Course in probability"-chaper4-discrete random variable-poisson distribution

Based on the concept of instrumental characterization of probabilistic problems, such as random variables, distribution columns, we can begin to discuss a variety of distribution columns. (This chapter is called "Random variables" in the book, but in order to separate from chapter fifth "Continuous random variables", here the title is "discrete Random variable")Poisson distribution derived from the two-item distribution combined series:We are familiar

"A first Course in probability"-chaper4-discrete random variable-negative two-term distribution

Based on our most familiar discrete distribution-two-item distributions, we can derive a number of other distribution columns, and for the previously introduced geometric distributions, we have given them the implication that the probability of success of an event is p, and the probability of the exact success of the N independent repetition experiment. Along the meaning of this layer, we have 1 times programmed R Times, then we get the so-called nega
