implementation code:The accuracy of this model on the training set is only about 60% accuracy, which certainly does not meet our requirements, we want to further train the model, create a data frame, deploy our model.Deploy the model to a dataset and compare it from the deployment of the model to the start of the team competition. The code and results are as follows:"Results of the group's predictions"Time 2:00Group: Spain, PortugalPredicted victory group: SpainTime 18:00Group: France, Australi

Calculus learning turning? It's a strange story. In fact, Calculus, like a car, turns slowly. In November 11, 1675, German mathematician Leibniz wrote the points and differential symbols in his notebook: Attention and D. This was the beginning of calculus. He insisted that differential dx is an infinitely small number (infinitesimal), So he developed paradoxing p

Rudin's This "functional analysis" is really not very good to read, in general, because the books in the details of the place is indeed too much, not very good grasp. I look at this book with the purpose of learning operator algebra, so I don't want to fall into the function space, especially the Fourier transformation problem associated with it, soAfter studying the relevant knowledge about the topological and space, the local convex space and the completeness, I studied the last three chapters

The mean value theorem for definite integrals:The definition of the integral itself is simple, but in the teaching process people often remember only its calculation method, in the introduction of the concept of integral, often it is tightly tied to the calculation method, in fact, in the simple definition of integrals, the basic theorem of calculus tells us the calculation method of integral.Basic theorem of calculus:Can see, it is based on such a ba

Original article link "If people don't believe in the simplicity of mathematics, they just don't realize the complexity of life ." -- Johnvon norann Dec mainly discusses extra points in discrete situations, which are used in the computer field. We know that it is impossible to use a computer to process geometric images completely smooth (the computer is a discretization world consisting of 0 and 1 ), the concept of Dec also provides us with a better tool to portray discrete ry. For example,

Differential Application 1.1 Differential 1.1.1 monotonicity, extremum and asymptote of unary functionThe derivative gives the direction of the function, which is very useful for the graphical properties of our analytic functions, and here we use the knowledge of calculus to understand the nature of the function. The effect of the first derivative on the function is the most direct one, where first-order derivative is seen. For the constant functio

In 1960 Abraham Robinson (1918-1974) solved the three hundred year old problem of giving a rigorous development of the calculus based on infinitesimals. Robinson's achievement was oneThe major mathematical advances of the twentieth century. This is an exposition of Robinson's Infinitesimal calculus at the advanced undergraduate level. It is entirely self-contained but is Keyed to the 2000 digital edition of

When it comes to calculus, everyone is unfamiliar, and people who go to college are basically the ones who have been on it, and countless people are hanging on that tall tree every semester ... Liberal arts students in the "University of Mathematics" in the look of its face, engineering students in the "higher mathematics" and it met, and science students in the "mathematical analysis" see its true colors. But to tell the truth, compared with other ab

It seems to us that calculus is called "decentralization" in secondary school, but in the Russian context it is necessary, not "decentralized", to teach calculus at the secondary level. This is why. Let's get things straight, and we can't just talk. According to the research of the School of Mathematics Science of Beijing Normal University, the course of "algebra and Mathematical Analysis preliminary" in 10

Recently more idle, intend to tidy up the previous study on the language of the program knowledge. The main content is to design the program language while writing the interpreter to implement it. This knowledge is essentially derived from programming Languages and Lambda calculi and essentials of programming Languages these two books. I remember the high School Olympiad training when the teacher said: "To solve problems must grasp the definition." "As with programming and reconciliation questi

Looking back, in 1908, calculus (also known as "micro-accumulation") was introduced into China. At the beginning, only a few people in China knew about calculus. After liberation, especially after the proposal of "entering science" in 1956, China began to learn about the Soviet Union in an all-round way. At that time, the Soviet scholar fekhincz wrote the "calculus
