IntroThe optimization problem is that given the objective function f (x), we need to find a set of parameter x so that the value of f (x) is minimized. Some common optimization algorithms are: Gradient descent (GD), batch gradient descent (BGD), random gradient descent (SGD), Newton, quasi-Newton, conjugate gradient, Momentum, Nesterov Momentum, Adagrad, Adadelta. Here's the next step. first, gradient decli

Gravity Field: the space in which the Earth's gravity acts. In this space, each point corresponds to a unique Gravity Vector. A variety of online games, whether 3D or the first perspective, or horizontal games (such as adventure Island), are required to simulate a gravity field. Let's review Google's birth in Newton...

the site The deviation is normal, but now it is completely helpless... [Mentioned in the masterpiece of qingrun :]: Yes. Maybe there may be a major change in the mathematical expression before we can describe such phenomena. The current mathematical description of some phenomena is always somewhat biased, not so accurate. However, Ms does not know where to develop.: Physics is still in a situation where it cannot be tested and described. more progress is required. What is lacking now is experim

The future is bright (A), and the road is tortuous (not ). The latter can be called an auxiliary theory. It is characteristic that it is special and cannot be deduced from the former itself, or it does not constitute a inferential relationship with the theory, and is not a necessary element of the system. To make the complex thinking op

the order of a function is greater than 2, fminunc is more effective than fminsearch, but fminsearch works better when the selected function is highly discontinuous.In Example 5-5, evaluate f (x) = 3 * X1 ^ 2 + 2 * X1 * X2 + x2 ^ 2.

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 tutorial" (three volumes of 9, ye yanqian translated) popular throughout the country, cultivate a large number of China's new genera

In many production-time problems, we tend to list a unary nonlinear equation based on known conditions, and one of the most typical examples is the problem of bank deposits, since their interest needs to be based on the principal and the previous year, so the index of the equation x is often higher. There is a series of nonlinear equations derived from the differential equation in the physical problem. Therefore, how to solve one-dimensional nonlinear equation is one of the important problems in

of mathematics and certainty M. Klein It turns out that mathematics is nothing more than human invention and speculation, and it is not necessary to enter the temple. I think that so many scientists (mostly mathematicians) who don't eat human fireworks in history think they have discovered the mysteries of cosmic operation, it's time to go down the altar.

The gradient method is a method between the shortest descent method and the Newton method. It only uses the first derivative information, but overcomes the disadvantages of slow convergence of the shortest descent method, this avoids the disadvantages of the Newton method in storing and calculating the Hesse matrix and finding the inverse. The gradient method is not only one of the most useful methods for s

The progress slowed down, mainly because I went to work! In addition, I get up at half past six every morning. If I don't work overtime at night and get home at half past seven, I can't study as casually as before. But I stick to it.This chapter describes the points. In advanced mathematics, there are about three important things. 1 is the meaning of the Cartesian points: Division, summation, and getting the limit. In this case, we can also solve some previously difficult limits; 2 is the
