In my years of developing Python applications, I’ve often found myself needing to generate a specific sequence of characters for formatting or data padding. Whether I was creating visual separators for a command-line tool or preparing fixed-width data for a financial report, knowing the quickest way to repeat a character is a handy trick. In … Read more >>
If you are a beginner in Python, you should start with a Hello World program as the starting point. Visual Studio Code (VS Code) is a powerful, open-source code editor that Python developers widely use. In this tutorial, I will explain how to write a Hello World program in Python using the Visual Studio Code … Read more >>
One of the most common tasks I handle as a Python developer is managing collections of decimal numbers. Whether I am building a financial dashboard for a Wall Street firm or a weather tracking app for the Midwest, I almost always reach for a list of floats. A list of floats in Python is simply … Read more >>
As a Python developer, I’ve found that one of the most common tasks is putting a variable inside a string. Whether I’m building a report for a client in New York or personalizing an email for a user in California, I always need to format text dynamically. There are several ways to do this in … Read more >>
Have you ever found yourself staring at thousands of customer support tickets or legal documents, wondering how to categorize them automatically? In my four years as a Keras developer, I’ve realized that assigning just one category to a text is rarely enough for complex, real-world data. Most documents belong to multiple topics at once, such … Read more >>
I’ve spent the last four years building deep learning models, and one thing I’ve realized is that Transformers can be quite heavy on resources. Recently, I’ve been experimenting with FNet, a model that replaces the complex self-attention layer with a simple Fourier Transform. In this guide, I’ll show you exactly how I use FNet for … Read more >>
Have you ever built a sentiment analysis model, only to realize you have thousands of reviews but zero labels? It is a common headache I have faced many times while working on large-scale Python Keras projects for retail clients. Manually labeling 10,000 reviews is not just boring; it is a massive waste of your technical … Read more >>
I have spent years building computer vision pipelines, and I can tell you that YOLOv8 combined with KerasCV is a game-changer. It simplifies the process of building high-performance models while keeping your code clean and readable. In this tutorial, I will show you exactly how to implement object detection. We will move away from generic … Read more >>
When I first started training deep learning models for image classification, I often relied on the standard Cross-Entropy loss. It worked well enough, but I noticed the models struggled when the classes were visually similar. I discovered that Supervised Contrastive Learning (SupCon) is a game-changer for these scenarios. It helps the model learn to pull … Read more >>
I’ve often found that the best way for a model to “learn” an image is by trying to fix a broken one. Masked Image Modeling (MIM) is a fascinating technique where we intentionally hide parts of an image and ask an Autoencoder to reconstruct the missing pieces. I remember the first time I applied this … Read more >>
