target value, the smaller the step, the slower the progression. The search iterations of the gradient descent method are as follows:Disadvantages of Newton's method:(1) The convergence speed is slowed down near the minimum value, as shown;(2) A straight line search may cause some problems;(3) The "zigzag" is likely to fall.It can be seen that the convergence rate of the gradient descent method is significa

the gradient estimation of the mean square error. KS in the formula is a negative number, its value determines the convergence of the algorithm, V "ε2 (n)" is the mean square error gradient estimation, The Adaptive filter is applied to automatic equalization, echo cancellation, antenna array beamforming, and other related domain signal processing parameters identification, noise cancellation, spectral estimation, etc. in the field of communication.

On the sender side, the convergence sub-layer is responsible for receiving the bit stream data from the application) or random length packets, and divides them into 44 ~ 48-byte unit for transmission. The exact size depends on the protocols used, because some protocols occupy part of the 48-byte ATM load as their own headers. At the receiving end, the child layer reassembles the cells in

this optimization problem are iterative algorithms of successive one-dimensional search, and the basic idea is to select a favorable search direction at an approximate point, and carry out a one-dimensional search in this direction to obtain new approximation points. This iterative iteration is known to meet the predetermined accuracy requirements. This type of iterative algorithm can be divided into two categories depending on the search direction:Analytic method: need to use objective functio

After a series of Route updates, each vro in the network has a complete route table, convergence. AS an internal Gateway Protocol (IGP), OSPF is used to publish route information between routers in the same autonomous domain (. Unlike the distance vector protocol (RIP), OSPF supports large networks, fast route

In order to seek the essence of gossip, the following content is mainly referred to gossip's original thesis: 1. Gossip background Gossip algorithm, such as its name, inspiration from the office gossip, as long as a person gossip about, in a limited time all people will know the gossip information, this way is similar to virus transmission, so gossip has a numbe

§11.5 function expands into power series First, Taylor series If there is a derivative of any order in place, we put the series (1) Called the Taylor series at the point where the function is. The part of its preceding paragraph and its use is recorded, and Over here: The Taylor median theorem, which is described in the previous book, has Of course, here is the Lagrangian residual item, and 。 by a 。 So, at that time, the Taylor series of functions is another exact expression of it.

X, y indicates that the THETA0 and theta1,z directions represent the cost function, and it is clear that the starting point is different, and the final convergence point may not be the same. Of course, if it is bowl

system theory before 1990s has two weaknesses. First, there is no systematic and effective way to obtain knowledge. Instead, you can only use an expert questionnaire, which is time-consuming and difficult to obtain satisfactory results; second, the lack of a complete theoretical system to ensure system stability, convergence, and other basic requirements. Since 1990s, the theory of fuzzy system has made breakthroughs in these two aspects. using vario

Therefore, the final objective function is: (yes Shorthand) The objective function can be iteratively optimized by the following procedure: Random initialization A repeats the following steps until convergence: according to a given in the previous step, the solution can minimize J (a,s) s based on the previous step, a

The gradient descent method is simple, and when the objective function is a convex function, the solution of the gradient descent method is the global solution. Under normal circumstances, the solution is not guaranteed to be the global optimal solution, the gradient descent method is not necessarily the fastest speed. the optimization idea of gradient descent method is to use the current p

At present, dynamic routing protocols are widely used. So I have studied the comprehensive comparison between the two commonly used dynamic routing protocols. Here I will share with you, hoping to help you. The earlier IGRP protocol was invented by Cisco and is a dynamic routing protocol based on the distance vector algorithm. The Enhanced Interior Gateway Routing Protocol is an Enhanced version of the IGRP Protocol. It belongs to the dynamic routing protocol of the dynamic Internal Gateway and
