In this article we are going to look at gradient descent and cost function in Python programming language. Mean Squared Error (MSE) In our school days we used to solve linear equations. For example consider the linear equation y=2x+3. For given x values, [1,2,3,4,5] we can calculate y values as [5,7,9,11,13]. However, in case of machine […]
In this article we will look at linear regression with multiple variables also called as multiple regression along with Python code. Let’s use another dataset which is a variation of the dataset used in our simple linear regression article. Download the modified house price dataset. The data is as shown below. Our new […]
In this article we will look at what is simple linear regression, the math behind it and then see hands-on implementation of simple linear regression in Python language. Let’s see how to predict home prices using a machine learning technique called simple linear regression. By simple we mean single variable regression. Regression is a […]
In this article we will look at what is machine learning, what is deep learning and some real world applications of machine learning. Source: readspeaker.ai Introduction First let’s talk about at what computers are good at and at what humans are good at. Computers can perform large calculations within milliseconds or even in seconds. […]
In this article we will look at Inodes in Unix file system and the commands for displaying and modifying the content of the Inodes in Unix. A file has several components like: name, contents, and administrative information such as permissions and modification times. This administrative information is stored in the inode, along with other […]
In this article we will look at file permissions in Unix with examples and commands associated with managing file permissions in Unix. Introduction Every file has a set of permissions associated with it, which determines who can do what with the file. If your directory contains files with sensitive information, we can change their […]
In this article you will learn about directories and file names in Unix with examples. You will also learn associated commands with directories and file names in Unix like ls, pwd, mkdir, cd and du. All the files in the system will have unique names. When we try to print the list of files […]
In this article you will learn about basics of files in Unix and what are files in Unix along with associated commands like od command and file command. Basics of Files in Unix A file is a sequence of bytes (1 byte = 8 bits). The meaning of the bytes in a file only depends on the […]
In this article you will learn some of the basic Unix commands along with examples. We will look at description of each basic Unix command followed by an example in XUbuntu operating system. After learning about basic Unix commands we will learn about command substitution and giving multiple commands in Unix. Unix Basic Commands […]
