Function: 1. Obtain the root of the equation. 2. Optimize the equation.First, select a function that is close to the zero point and calculate the corresponding and tangent slope (the derivative of the function here ). Then we calculate the

1. Newton's first Law All objects always remain in a state of uniform motion or stillness, unless the force acting on it forces it to change this state. This is Newton's first law. Newton's first law is also called the law of inertia. 2.

After expansion, it is a polynomial, When polynomial is equal to 0, what is r equal? This problem does not have a precise solution (resolution), b

documents. The results obtained after listing are astonishing, and user feedback is enthusiastic. This reminds me of the story of the original invention of PDA. Apple, which has always been an innovative company, has created the first handheld computer, Newton. However, due to its large size and slow computing speed, the problem of poor handwriting recognition performance lies in the market. However, one p

nothing to do with particle fluctuations, but has aroused heated debate on the color attributes. In the eyes of gleemadi, the difference in color is caused by the different frequencies of light waves. His experiment attracted interest from Robert Hoke. Hooku was originally a lab assistant to poyier, a member of the Royal Society of England, and also a lab administrator. He repeat greemadi's work and carefully observes the colors mapped by light in the soap bubble and the radiance of light over

Each of us in our life or work encountered a variety of optimization problems, such as each enterprise and individual to consider a problem "at a certain cost, how to maximize profits" and so on. The optimization method is a mathematical method, which is a general term for some disciplines that study how to search for certain factors under a given constraint, so as to make certain (or some) indicators reach the optimum. With the deepening of learning, bloggers are increasingly discovering the im

Design What are the user experience design goals? The most important thing is to make the product useful, this usefulness refers to the user's needs. Apple's 90 generation of the first PDA phone, called Newton, is a very failure of a case. In that era, in fact, many people do not need a PDA, Apple put more than 90% of the investment in his 1% market share, so the

landscape for decades. The user experience is the third kind of innovation, which can bring great development to the enterprise. When Apple launched the ipod five years ago, there were already a lot of MP3 player products on the market. The ipod itself has no special function, that is, play, pour song, but Apple in the user experience has done a very good innovation, things very easy to use, very simple. ipod to add features, you can add a lot of such as to delete a song, such as buy a song to

Newton, is a very failure of a case. In that era, in fact, many people do not need a PDA, Apple put more than 90% of the investment in his 1% market share, so the failure is inevitable. The second is ease of use, which is critical. Not easy to use the product, is also useless. There are more than 150 kinds of brands on the market, each cell phone has one hundred or two hundred kinds of functions, when the

It is estimated that some readers will find this topic to be very mathematical, and natural language processing does not matter, but if you have heard the maximum entropy model, conditions with the airport, and know that they are widely used in natural language processing, and even you understand that its core parameter training algorithm is called LBFGS, So this paper is a preliminary introduction to this kind of quasi-newton method for solving uncon

. Framework of One-element Calculus First, we will give a framework map of one-dimensional calculus, which corresponds to the Tongji edition of Advanced Mathematics (I ). Let's just give a simple explanation and then describe it one by one. 　　①The limit of functions and functions is the foundation of calculus; 　　②Calculus consists of three parts:Differentiation,PointsAnd points out that differentiation and integration are a pair of ContradictionsBasic theorem of calculus (

to meet the precision requirements. This is easy to understand, because it usually requires three to four iterations to obtain an accurate result. To increase the convergence speed, we need other methods.2 Newton Iteration Method The principle is also relatively simple,It is to replace the mean value with the zero root of the tangent equation as the final solution.The principle can be explained using (from matrix67 ): Fig 1

iteration, calculate the descent direction of the objective function in each iteration and update W until the objective function is stabilized at the smallest point. As shown in Figure 2. Figure 2 Basic steps for solving the optimal objective function The difference between the different optimization algorithms lies in the calculation of the target function's descent direction dt. The descent direction is obtained by first-order reciprocal (gradient, gradient) of the objective function under th

The most important thing is to make the product useful, which refers to the user's needs. Apple's first PDA mobile phone, Newton, came out in 1990s, which is a very failed case. In those days, many people did not have the need for PDAs. Apple put more than 90% of its investment in his 1% market share, so the failure was inevitable. The second is ease of use, which is critical. Products that are not easy to
