Autoencoders are a highly effective category of neural networks utilized for unsupervised learning and reducing the dimensionality of data. They possess the ability to learn compact representations of input data by encoding it into a latent space of lower dimensions and subsequently decoding it to restore the original input. This article delves into the workings of autoencoders in Python, specifically employing the Keras library, to provide a comprehensive understanding of their functionality. What are autoencoders? Autoencoders are a specialized form of neural networks designed to reconstruct input data. They consist of two main parts: a decoder network, responsible for recreating ... Read More

In Python, variables are stored differently based on their type and scope either it can be stored in the heap or in the stack which are the two main memory regions utilized for a variable storage. Python, being a high-level programming language, abstracts away many low-level memory management details from the programmer. However, it's still essential to understand how variables are stored in Python to write efficient and optimized code. In this article we will see How are variables stored in Python (Stack or Heap). Stack The stack is a region of memory used for storing local variables and ... Read More

One of the most crucial aspects of data analysis is proficiently visualizing data to pinpoint trends and patterns rapidly and a highly effective tool to visualize categorical and continuous variables is by using a horizontal strip plot with jitter . Our article will demonstrate how to create horizontal stripplot with Jitter utilizing Altair—a popular Python library renowned for its declarative statistical visualization features. What are Stripplot and Jitter? A stripplot displays individual data points in a horizontal arrangement, allowing us to observe their distribution across different categories. However, when multiple data points share the same horizontal position, they can ... Read More

Boxplots are one of the most popular tools available for data visualization of the datasets which is mainly created using a python library called Seaborn, which provides a simple and powerful way to create both horizonatal and vertical boxplots and other types of visualizations. In this article, we will be focusing on how to create a horizontal boxplot with points using Seaborn in Python. What is a boxplot? First of all, let’s define what a boxplot is. A boxplot is a graphical representation of the dataset that convey the distribution of the data in the dataset using outliers, quartiles, and ... Read More

While working with clustering algorithms in Python, it is important to be able to evaluate the performance of the models, and one of the popular metrics for evaluating the performance of the clustering model is the homogeneity score using sklearn. It measures how well the labels assigned by a clustering algorithm match the true labels of a dataset. The higher the homogeneity score, the better the clustering algorithm performed. In this article, we'll take a closer look at the homogeneity score and how to compute it using Scikit-learn in Python. What is the Homogeneity score? The homogeneity score is the ... Read More

Holistically-Nested Edge Detection (HED) is a deep learning-based method for detecting edges in images which can be performed using deep learning and a Python library, OpenCV. The holistically-Nested Edge detection was first introduced by Xie and Tu in 2015 and has since been widely used in computer-vision applications.Currently, it has gained a lot of popularity in recent years due to its ability to produce accurate and high-quality edge maps in an image. In this article, we will discuss the basics of HED, how it works, and how to implement it using OpenCV and deep learning, and also using Canny ... Read More

Histograms are the graphical representations of the dataset distribution and can be created using Plotly , a Python library with a class known as graph_objects, using which we can create the histogram. Histograms are useful for understanding the shape of the dataset which also includes outliers, central tendency, and spread. Plotly is a Python library that allows us to create interactive visualizations in various formats, including scatter plots, line charts, and histograms. The class graph_objects provides a high-level interface for creating some complex charts and allows us to customize every aspect of the plot. In this article, we will be ... Read More

Many applications benefit from sorting pandas DataFrame by column names or row indexes. For example, to show how sales continue over time, we may sort a DataFrame of sales data by date. In Python, we have some built-in functions- DataFrame(), sort_index(), and, sort_values() that can be used to Sort a Pandas DataFrame based on column names or row index. Syntax The following syntax is used in the examples − DataFrame(var_name, colums= ['col1', 'col2', and so on], index= ['1', '2', and so on]) A DataFrame is a library of pandas modules and defines the 2D structure of different rows and ...
