Matplotlib is a popular data visualization library used in python. It has wide range of tools and techniques for creating different types of plots. When we work in data visualization, color plays an important role in conveying information and making the work more appealing and easy to understand. We will start with the basics of Matplotlib, pyplot, creating graphs and then different methods to change the color of a graph plot with various examples. What is Matplotlib? Matplotlib is a simple interface for making different plots, where you have a variety of options to make changes to the plots. ... Read More
Introduction The success of machine learning algorithms depends on the quality of the data they use to extract knowledge. Machine learning algorithms may produce inaccurate or unintelligible results if data is inadequate or contains irrelevant information. By removing irrelevant and redundant information before learning, feature subset selection algorithms aim to reduce the amount of time it takes to learn. It reduces data dimensionality, improves algorithm efficiency, and enhances performance and interpretability. Feature subsets are evaluated using a correlation-based heuristic in a new feature selection algorithm. Three common machine learning algorithms are used to evaluate the algorithm's effectiveness, and experiments ... Read More
Introduction Spectral analysis plays a crucial role in understanding and modeling sinusoidal components in various fields such as statistics, signal processing, and time series analysis. Sinusoidal models are widely used to approximate sequences of data by fitting them to sine functions In this blog, you will be able to understand the spectral analysis in sinusoidal models, its applications, and the process of fitting a sinusoidal model to data. Understanding Sinusoidal Models A sinusoidal model aims to approximate a sequence of data points, denoted as Yi, using a sine function. The model can be represented as follows: "Yi = C ... Read More
Autoencoder networks, which are also referred to as auto-associative neural networks, are a specific type of neural network that is really good at replicating input patterns at the output layer and they can be achieved significant accomplishments in various domains, such as identifying patterns, analyzing biological information, recognizing speech, and validating signals. By mimicking and investigating the process of association, these networks offer a highly effective tool for representing data and reducing its complexity. A training procedure is used in auto-associative neural networks to collect input patterns and their related outputs. Even when the inputs are distorted or loud, the ... Read More

Introduction When training a neural network in deep learning, it is important to choose the right architecture and hyperparameters. Evaluating the network's performance on unseen data during training is crucial. PyTorch provides tools for creating and training neural networks in Python. To evaluate the neural network's testing accuracy, a validation set can be introduced. Installing PyTorch Let's ensure that we have the necessary dependencies installed before training neural networks in PyTorch. Using pip or conda, PyTorch can be installed. For computer vision tasks, run the following commands to install PyTorch along with the torchvision library: "pip install torch torchvision" ... Read More
Visualization tools are a vital part of Matplotlib library. One of the tools is colorbar. It shows the mapping between data values and colors in a plot. For adjusting the size of the colorbar to make it more visible or to fit it better with the plot we have several parameters presented by the colorbar() function in Matplotlib. In this article, we will discuss how to change matplotlib colorbar size using different approaches. What is Matplotlib and How to Install it? Matplotlib is a widespread library for creating static, animated and interactive visualization in python. It has module ... Read More
