The commonly used exponential smoothing methods are first exponential smoothing, second exponential smoothing and third exponential smoothing. Higher exponential smoothing is rarely seen. Therefore, this paper focuses on the characteristics and differences of first, second and third exponential smoothing. One-time exponential smoothing is gene ...

I found some high-profile and high-profile questions from Stack Overflow.These questions may not normally be encountered, but since the highly focused questions and highly praised answers are generally accepted, they will be more handled in the future, whether at work or in interviews, if we learn in advance.This article is the first week's con ...

Derivation formula We've learned the simplest list derivation and generator expressions before. But in addition, there are dictionary derivation, set derivation and so on. The following is a detailed derivation format with list derivation as an example, which is also applicable to other derivation. variable = [out_exp_res for out_exp in input ...

[python implements convolution neural network] convolution layer Conv2D implementation (with stride, padding) Needless to say more about how convolution is done, consider how convolution layers are implemented step by step with your code. Code Source: https://github.com/eriklindernoren/ML-From-Scratch First, take a look at its basic component f ...

cover Understand what Promise objects are In the project, there will be various asynchronous operations. If there are asynchronous operations in the callback of an asynchronous operation, there will be a callback pyramid. Like the following // Simulate to get the code, then pass the code to the background, get userinfo after ...

What is LACP?Based on the LACP of IEEE802.3ad standard, the full name of Link Aggregation Control Protocol in English is translated into Chinese as Link Aggregation Control Protocol, which is used to achieve link dynamic convergence and de-convergence.LACP interacts with its peers through LACPDU.DU refers to Data Unit, a data unit.MAC addres ...

This article mainly talks about the functions commonly used in Oracle, as well as the knowledge of type conversion. Note: date type is troublesome, but date format is indispensable in practical application. Single-Row Functions Single line function: only one parameter input and only one result output --1,Study lower/upper/initcap Function ...

Closure of popular understanding Let's see what a closure is first A closure is a function that references a free variable. This referenced free variable will exist with this function, even if it has left the environment in which it was created. So, there is another way of saying that a closure is an entity composed of a function and its assoc ...
