Introduction Linear regression is one of the most used and simplest algorithms in machine learning, which helps predict linear data in almost all kinds of problem statements. Although linear regression is a parametric machine learning algorithm, the algorithm assumes certain assumptions for the data to make predictions faster and easier. Homoscadastocoty is also one of the core assumptions of linear regression, which is assumed to be satisfied while applying linear regression on the respected dataset. In this article, we will discuss the homoscedasticity assumption of linear regression, its core idea, its importance, and some other important stuff related to the ... Read More
We can use JavaScript Math.random() method to generate random values. JavaScript provides us with different Array methods, such as from(), fill(), and push(), that can be used to create an array with random values. Arrays in JavaScript are a powerful feature that allows you to store a collection of values of different data types. They are widely used in many applications, and having an array with random values can be very useful in certain scenarios. An array of random values is a collection of randomly generated numbers stored in an array. The values in an array of random values can ... Read More
The intersection of two arrays in JavaScript can be done in different ways, such as using the Set, spread operator, filter() method, or the includes() method. Each method has its own advantages and disadvantages, and it is important to consider which method works best for the given task. The intersection of two arrays is helpful if you want to create a new array that contains only the elements found in both arrays. Let’s have an example − arr1 = [ 2, 5, 7, 9, 11, 13, 15, 17 ] arr2 = [ 1, 3, 5, 7, 11, 13, 16, 17 ... Read More
Arrays are one of the most commonly used data types in JavaScript. They are used to store collections of data and allow for efficient access and manipulation of data. Arrays can contain any type of data, including primitive values, objects, and even other arrays. The technique of creating an array of partial objects from an array is a valuable technique when dealing with complex data sets. Partial objects contain only a subset of the data from the original array, allowing us to focus on a particular set of data. This can be especially useful when dealing with large data sets, ...

In JavaScript, we can use window.location object to force a page to load another page. We can use the location object to set the URL of a new page. There are different ways – window.location.href property, window.location.assign() and window.location.replace() methods, to set the URL of a new page using the location object. We will discuss each of the property and methods in detail in this tutorial. Window.location.replace The first way is to use the window.location.href property. This property contains information about the current URL of the page, and it can be used to redirect the user to a new page. ... Read More
Shooting stars appear to be the gleaming indications of the warmth produced as these small shivers make a blip in the frigid night sky. The Shooting Star effect is one of the most unique background effects for dark-themed websites. Shooting Stars Animation is a fantastic example of a loading screen that keeps your attention for a long time while the rest of the material on the website loads. This effect can be utilised in page loaders and user interfaces. In this article, we will discuss about the method to create Shooting Star Animation effect using CSS. For this, we will ... Read More
As the ‘heap out of memory’ error message suggests, it occurs when any JavaScript code takes more memory than allocated memory, when we run any JavaScript program, the computer allocation particular memory to the JavaScript program. When we run code of JavaScript or any programming language, our computer creates a process and allocates fixed memory. When a program needs more memory size, it raises an error like heap out of memory. For example, if we create an array of size 1020 and try to initialize every array index with some value, the heap goes out of memory and raises ... Read More
In the Go, a binary tree is a tree data structure where each node has at most two children, as the left child and the right child. Go's built-in data structures and operations, like structs and pointers, can be used to create a binary tree. The tree's nodes can be visualized as structs with fields for the value kept at each node and pointers to any left or right children. There are three types of tree traversals- preorder, inorder and postorder. We will use two methods to implement the binary tree data structure. In the first method we executed pre-order ... Read More
We can optimize our web application in various ways, and cause our web page to load faster, and in a more efficient way, which not only will reduce the load on the web servers, but also increase the SEO rankings of the website. Let’s discuss the different ways through which we can optimize the web page, and understand them with the help of examples. Approach 1: Minimize the File Size as Much as Possible File size should be minimized as much as possible. This can be achieved by trimming unnecessary whitespaces from within the file, removing unnecessary comments, and/or replacing ... Read More
The important statistics collected for a performed query, including time, temporary tables, indexes, joins, and more, are gathered in the Query Stats SQL editor results tab (see the following two figures). Requirements Enabled query, and collect performance schema statistics. The performance_schema has statement instrumentation enabled. SQL Editor: Query Stats Visual Explain Plan By utilizing the additional data included in the enhanced JSON format, the visual explain feature creates and presents a visual depiction of the MySQL EXPLAIN statement. All EXPLAIN formats, including the standard format, the raw extended JSON, and the visual query plan, are available in ... Read More
