10.20速通带英，直布罗陀之旅

【🇬🇧🇬🇮10.20 直布罗陀】

趁着签证还没过期，一日速通带英（真）

终于见到西班牙国旗🇪🇸上的海格力斯之柱了，一边是直布罗陀巨岩，另一边是摩洛哥的摩西山（或者是休达的雅科山）。地中海门户直布罗陀海峡，地理书的常客，实际看来也挺窄的，像这次天气好直接就能看到对岸的非（广）洲（州）

最后回到西班牙境内跟回到家了一样，令人感叹，终于不用说英语辣😭

Supervised and Unsupervised learning in machine learning

Machine learning is a subject of artificial intelligence, which means programming computers in terms of algorithm so that they can learn from data. Supervised learning and unsupervised learning are two types of Machine Learning systems. One can easily tell the difference between them by the criterion: whether or not they are trained with human supervision. Supervised learning and unsupervised learning are two extreme. The former completely depends on human supervision, while the latter doesn't n ...

AI: Deep Learning vs Machine Learning

In the previous article Supervised and Unsupervised learning in machine learning, we explains the meaning of machine learning. As AI is making waves across industries, we often hear the terms "deep learning" and "machine learning" getting thrown around interchangeably. While both are crucial for AI advancements, they are indeed two different subjects with distinct characteristics. Deep learning is a branch of machine learning, whose methods are based on artificial neural networks (ANNs). In othe ...

An introduction to different branches of mathematics

The note is mainly a sketch of basic knowledge concerning general topology, differential geometry, functional analysis, algebraic geometry, etc., starting from a discussion of Euclidean spaces. However, there maybe some mistakes in the note, so use at your own risk. For simplicity, some details are omitted and can be found in the references provided. Further materials concerning algebraic geometry, especially arithmetic algebraic geometry, can be referred to another note written by the author, N ...

How to do syntax highlighting for code blocks in Nuxt?

How to setup PrismJS and Autoloader plugin with Nuxt 3?

In previous the article Mathjax loads slow. How to load local JS file with Nuxt?, we explain how to render math equations in Nuxt.js using local CDN. With local CDN, we could easily load many Javascript libraries without slowing down our page loading.PrismJS is a light Javascript library that highlights the code blocks on your pages. In the ordinary way that setup PrismJS (see How to do syntax highlighting for code blocks in Nuxt?), you need to import the file of almost every language that you n ...

How to find similar strings with python?

Suppose that we have a string str together with a list of strings arr = [str1, str2, ... ]. How to find similar string of str in arr? To do this, we can calculate the similarity of str and elements in arr one by one. But how to calculate the degree of similarity between str and an element in arr? First, we need a measurement of the similarity of two strings. In fact, there are many methods that measure the similarity of strings. In this tutorial, we will use python to find similar strings of str ...

Django use icontains with in for field lookup

In Django, __icontains and __in are field lookups to the QuerySet methods. __icontains is a case-insensitive containment test, and __in means that the field is in a given iterable. So I would like to do the following lookup:keywords = ['How', 'to', 'setup', 'PrismJS', 'and', 'Autoloader', 'plugin', 'with', 'Nuxt', '3?'] #Possible keywords of title Writings.objects.filter(title__icontains__in=arr)Unfortunately, we can not combine field lookups in Django. To implement our desire, we can use Q() ob ...

Mathjax loads slow. How to load local JS file with Nuxt?

In How to render math in Vue or Nuxt?, we explain the way to use Mathjax to render beautiful math formula in Nuxt.js. However, using CDN to load Mathjax is easy, but it degrades the performance of our pages. In other words, Mathjax may load slow if it is loaded by CDN.One of the solutions is to load Mathjax locally. You can use npm to install Mathjax to your project. npm install mathjax@4.0.0-beta.6However, it is difficult to integrate with Mathjax in Nuxt. Not only because there is little infor ...

Proof of the isomorphism $\textrm{Hom}_{A-mod}(\textrm{Hom}_{A-mod}(A,A),A)\cong A$ for any ring $A$

Let $A$ be a commutative ring with identity. Then we have an isomorphism $$A \rightarrow \textrm{Hom}_{A-mod}(A,A), a \mapsto (x \mapsto ax)$$, whose inverse is $$\textrm{Hom}_{A-mod}(A,A) \rightarrow A, \varphi \mapsto \varphi(1).$$Then applying this isomorphism, we get $$\textrm{Hom}_{A-mod}( \textrm{Hom}_{A-mod}(A,A) ,A) \cong \textrm{Hom}_{A-mod}(A,A) \cong A.$$
