A Dictionary is one of the data structures available in python which stores the data in the format of key and value pairs. It is mutable i.e., once the data is defined in the dictionary we can make the modifications on the data. It is an unordered collection of elements. The key in the dictionary is unique and the values can be duplicates. The key and value are separated by using the colon (:). On the other hand, a tuple is an ordered collection of elements, enclosed in parentheses (), separated by commas. It is immutable, which means the values ... Read More

Python NetworkX is a popular open-source Python library used for the creation, manipulation, and analysis of complex networks or graphs. It provides a wide range of tools, algorithms, and functions to work with graphs, making it a valuable resource for network analysis and research. Python NetworkX allows us to represent and work with different types of graphs, such as directed graphs, undirected graphs, multigraphs (graphs with multiple edges between nodes), and weighted graphs (graphs with edge weights). It also provides a simple and intuitive interface for creating, adding nodes and edges, and performing various operations on graphs. Installation and importing ... Read More

Generally, a string is an immutable data structure which is used to store the data in the string format within the single quotes or within the double quotes. It is immutable which means once the string is created the data in the string can’t be changed but can perform various operations on strings to manipulate the data A substring is a contiguous sequence of characters within a larger string. It is a smaller part of a string that can be extracted or searched within the original string. For example, let’s consider the string "Hello, World!" as the original string and ... Read More

Introduction Statistical modeling is a powerful technique used in data analysis to uncover patterns, relationships, and trends within datasets. By applying statistical methods and models, researchers and analysts can gain insights, make predictions, and support decision-making processes. R, a popular programming language for statistical computing and graphics, offers a wide range of tools and libraries for statistical modeling. In this article, we will delve into the world of statistical modeling with R, exploring its key concepts, techniques, and applications. Understanding Statistical Modeling Statistical modeling is the process of formulating mathematical representations or models that describe the underlying structure of data. ... Read More

Seaborn's 'axes_style()' function allows us to customize the style of plots by modifying various parameters. It returns a dictionary of parameters that control the appearance of the plot elements, such as colors, fonts, gridlines, and more. To view these parameters, we can print the dictionary returned by 'axes_style()'. Importing Required Libraries Before we begin, let's import the necessary libraries. We need to import Seaborn by using the following command. import seaborn as sns Viewing Parameters To view the available parameters in 'axes_style()', we can simply print the dictionary returned by the function. Example When we run the below code, ... Read More

In this article, we will explore how to convert an RGB image to a binary image using MATLAB programming. An RGB image is one which is represented by using three color channels namely, Red, Green, and Blue. In the case of an RGB image, the three primary colors, namely red, green, and blue are used to represent all the colors in the image. In the RGB image, each pixel of the image is represented by a combination of intensity values for these three colors. Therefore, the three intensity values of RGB colors determine the color of the pixel. In MATLAB, ... Read More

HSI (also called HSV) and RGB are two different types of color spaces. Where, HSI stands for Hue Saturation and Intensity, (HSV stands for Hue Saturation Value). An image represented based on the color model of HSI is called an HSI image. On the other hand, RGB stands for Red Green and Blue. It is another popular color space in which images are represented based on red, green, and blue color intensities. In this article, we will study how to convert an HSI image into an RGB image using MATLAB programming. MATLAB provides a built−in function ‘hsv2rgb’ to convert an ... Read More

Time complexity is a measure of time, which determines the time required for the algorithm to execute. It also checks how the running time is being increased when the size of the inputs is getting increased. The time complexity is represented with the notation capital O, which sets an upper bound in the worst case performance of an algorithm. Whenever we design an algorithm we should keep in mind not only about the correctness but also about the time complexity and performance characteristics. For example, if an algorithm has time complexity O(n) that would take twice of O(n) to execute ... Read More

In digital image processing, the process of extracting a specific color or color range from an image with all other colors are discarded is referred to as color slicing. In an image, the color slicing is performed by creating a binary mask that selects all the pixels in the image that lies in the range of the specified color. Coloring slicing is generally used in specific color spaces such as RGB (Red−Green−Blue) color space or HSV (Hue−Saturation−Value) color space, etc. In this article, we will learn how to perform color slicing in HSV color space using MATLAB programming. In the ... Read More

The name-tools module is a python library which provides us the tools to work with the names. These are used in many applications likely data cleaning, text processing and Natural Language Processing etc. It has a several functions for comparing and managing the names. Installing name-tools Before working with the name-tools, we need to install it in the python environment. The following is the process for installing the name-tools. pip install name-tools After executing the above code, if you see the text below, then the installation is considered successful. Collecting name-toolsNote: you may need to restart the kernel ... Read More
