Matplotlib is free and open-source plotting library in python. It is used to create 2-Dimensional graphs and plots by using python scripts. To utilize the matplotlib functionalities we need to install the library first. Install using pip By execute the below command in the command prompt we can easily install the latest stable package for Matplotlib from PyPi. pip install Matplotlib You can install Matplotlib through conda, using the following command – conda install -c conda-forge matplotlib A Contour plot is used for visualizing three-dimensional data in a two-dimensional surface by plotting constant z slices, called contours. ...

A matplotlib-based Python visualization package is called Seaborn. It offers an advanced drawing interface for beautiful statistics visuals. It is based on Matplotlib and supports the pandas and numpy data structures and the statistical functions from scipy and statsmodels. A connection involving categorical data may be shown in seaborn in various ways. There are two ways to create these charts, which is similar to the relationship between relplot() and either scatterplot() or lineplot(). There are various axes-level methods for charting categorical data in various ways, and the figure-level interface catplot() provides uniform higher-level access to them. What is categorical data? ... Read More

With the expansion of digital communication, spam has grown to be a serious issue for people all over the world. Spam can not only waste the recipient's time but also pose a security concern since it occasionally contains harmful code or phishing links. To solve this issue, a number of machine-learning techniques are used to recognize spam transmissions. One of them, the Naive Bayes algorithm, has been demonstrated to be effective in identifying spam. In this blog post, we'll look at ways to make the Naive Bayes algorithm for identifying spam better. What is the Naive Bayes Algorithm? The Naive ... Read More

In machine learning and data mining, clustering is a frequently used approach that seeks to divide a dataset into subsets or clusters based on their similarities or differences. Applications like consumer segmentation, fraud detection, and anomaly detection frequently employ clustering models. Nevertheless, there is no one method that works for all datasets and clustering algorithms, therefore assessing the effectiveness of clustering models is not always simple. In this blog article, we'll go through the important elements of assessing the effectiveness of clustering models, including several evaluation metrics and methods. Understanding the Basics of Clustering Let's quickly go over the fundamentals ... Read More

For machine learning models to perform at their best, selecting the right classifier algorithm is essential. Due to the large range of approaches available, selecting the best classification algorithm could be challenging. It's important to consider a range of factors when selecting an algorithm since different algorithms work better with different types of data. One of these factors is the quantity of training data. On how effectively the classification system performs, a large training data set can have a substantial impact. The performance of the classifier generally increases with the size of the training data set. This isn't always the ... Read More

In order to predict future values using the data at hand, time series analysis frequently employs Autoregressive Integrated Moving Average (ARIMA) models. These models use the moving average and autoregressive coefficients to represent the link between past and future data. For the model to be trustworthy and accurate, it is crucial to comprehend the criteria for these coefficients. This blog article will look at the requirement for the ARIMA model coefficients and their importance. What are ARIMA Models? ARIMA models are statistical time series data analysis models. They have three components: autoregressive (AR), integrated (I), and moving average (MA). The ... Read More

One of the most commonly used types of graphs in data visualisation is the pie chart. A pie chart is a circular chart that is divided into slices to represent the proportion of different categories in a dataset. Seaborn is a Python data visualization library that is built on top of Matplotlib, which is another popular Python visualization library. Seaborn provides a high-level interface for creating a wide range of statistical graphics and can produce more sophisticated and aesthetically pleasing visualizations than Matplotlib. Matplotlib is a low-level library for creating basic graphs and charts in Python. It provides ... Read More

What is matplotlib? Matplotlib is a popular, open-source data visualization library in Python widely used in the scientific, engineering, and data sciences fields. Matplotlib is known for its flexibility and vast range of customizable options, which makes it a great choice for creating complex visualizations for research or data analysis purposes. One of the most popular types of visualization is the grouped bar chart, which allows comparing multiple variables side by side while showing the differences between groups or subcategories. In this tutorial, we will show you how to create a grouped bar chart in Matplotlib using real-world examples. What ... Read More

Candlestick charts are a popular way to visualize stock market data. They show the opening, closing, high, and low prices of a stock or security for a given time period. A candlestick chart consists of a series of vertical bars or "candlesticks", where each candlestick represents one time period. The top and bottom of each candlestick represent the highest and lowest prices traded during that period, while the body of the candlestick represents the opening and closing prices. In this tutorial, we will explore codes where we will use Matplotlib, a popular data visualization library in Python, to create a ... Read More

OSI termed Open Systems Interconnect is developed in the year 1983 by ISO (International Organization for Standardization) professionals and it has been declared as an international standard of communicating through the network in later 1984. This model consists of seven layers of abstraction which are used for the transmission of data from a device through the channel to another device. Each layer is designed to do its task by getting data in the form of bits or packets and then forwarding the processed data to the upper layers in the architecture. Architecture designed in the OSI model helps the network ... Read More
