Unsupervised Machine Learning

 Unsupervised learning is the learning in which there is only input variables and not output variables corresponding to that input variable. Unsupervised learning is a type which is used to draw conclusion from dataset containing input data without any label. An unsupervised learning means the case of data in which there is no expected output related to that input data . The algorithm of unsupervised learning finds the pattern which depends on the values of data inputted.

One of the most important application of unsupervised learning is CLUSTERING in which inputs of same category or types are kept together in order to form the cluster of input data.  The above picture represents the process of clustering in which different varieties of fruits are grouped together as input and the output is in cluster form. In the unsupervised learning, the algorithm itself is not capable of adding label which means that it cannot identify the meaning of the output given.

It is called unsupervised learning because in this type there is no conformation of correct answer and there is no teacher as algorithm are left to find the pattern by their own in the data .

The model is trained using unsupervised learning algorithm. The clusters are formed on the basis of this training only.

 

Some of the popular  uses of Unsupervised Learning are –

3.2.1.Banking sector- It is used in banks for part customers accoerding to their behaviour by many surveys to divide them in clusters.

3.2.2.Healthcare-  This technique is used in MRI and Cityscan process to differentiate between normal and abnormal pictues.

3.2.3.Retail sector- It is used to recommend product to customres based on their past purchases.

Back-end Development

  Web applications behind the scenes are controlled by Back-End Development. Back-end is used to create Front-end by utilizing a database. Back-end can be written in various coding system and dialects, for example, v php- php document is an ASCII record, made using any ASCII editor (Notepad and Notepad++). Html codes are written in php files and can be easily embedded. v JAVA- JAVA is one of the most liked programming languages. It was developed in early 90’s by sun microsystems. Father of Java is James Gosling and it is high level programming language. v Python- Python language is being utilized at both small and huge scale due its adaptable nature and numerous programming ideal models like object-oriented, imperative, functional and procedural.

Other Tool in Web Development

JavaScript- JavaScript is a lightweight, interpreted, dynamic programming language that is used to make dynamic web pages and applications. It was came out in 1995 with the name LiveScript but afterwards its name is changed into JavaScript as it is integrated with Java. Bootstrap- It is the most popular framework for faster and easier web-development. The reason why we use bootstrap is that it is supported by almost all popular browsers, easily get started ( anyone who has knowledge of just HTML & CSS can start with it ), its responsive design, it also contains JavaScript plugins. AJAX ( Asynchronous JavaScript and XML )- It is a group of coherent client-side & server-side technologies by using which we can update a part of a webpage instead of reloading the whole webpage. We can take the examples of sites like YouTube, Gmail, Google-maps, tabs within Facebook etc. It increases the speed and usability of web pages and application. JQuery- It is JavaScript library whic...

History and versions

  - HTML was created by Tim Berners Lee in 1991. He considered it to be an application of SGML (Standard Generalized Markup Language).”HTML 2.0” was published in 1995. “HTML 4.01” was published in 1999. Although “HTML 4.01” version is widely used yet currently “HTML 5” is used more commonly and it was published in 2014.    HTML was originally developed with the intention of evaluating the structure of document like headings, lists, paragraphs etc. to give the facility of sharing information between scholars.   But now, it is being   commonly used for format web-pages .   o How we write code in HTML/Use- HTML is specified as TAGS in an HTML document. HTML Tags- It is basically word or group of words enclosed between Angle Brackets as <html>. Usually, These Tags comes in pair as <h1>   &   </h1> , that are wrapped around some text. They are called Container tags. 1st tag in the pair is opening tag and the 2nd one i...
