I have found that a pie chart is only as good as its labels. Without clear percentage markers, your audience has to guess the proportions of your data. The autopct parameter in the Matplotlib pie() function is the primary tool we use to display these percentages automatically. It calculates the share of each slice and … Read more >>
In my years of working with data visualization, I have found that a default white background rarely fits a professional dashboard. A well-chosen background color makes your Python Matplotlib pie charts pop and aligns them with your brand’s aesthetic. In this tutorial, I will demonstrate how to manipulate the background colors of your pie charts … Read more >>
I’ve often felt like I was working with a “black box.” It’s one thing to get 98% accuracy on a dataset, but it’s another thing entirely to know why the model made that choice. I remember working on a project for a local botanical garden where the model was identifying invasive plant species. I needed … Read more >>
As a Keras developer who has spent the last four years building computer vision models, I have always been fascinated by how Vision Transformers (ViT) “see” the world compared to traditional CNNs. When I first transitioned from ResNet to ViT, I struggled to understand how these global self-attention mechanisms actually processed my image data. In … Read more >>
I’ve often been asked a tough question by stakeholders: “Why did the model make this specific decision?” Deep learning models are often seen as “black boxes,” which makes it difficult to trust them for high-stakes tasks like financial forecasting or healthcare. I remember the first time I deployed a neural network for a real estate … Read more >>
Convolutional Neural Networks (ConvNets) often feel like a “black box” where data goes in, and predictions come out. During my four years of working with Keras, I’ve found that seeing what the layers actually “see” is the best way to debug a model. In this tutorial, I will show you how to peel back the … Read more >>
I remember when I first tried to build a search tool for my personal photo gallery. I used simple tags, but it was a nightmare to manage thousands of photos manually. That’s when I discovered Dual Encoders in Keras. It changed everything because I could finally search for “a sunset over the Grand Canyon” and … Read more >>
Over the last four years of building deep learning models, I have found image captioning to be one of the most rewarding challenges in computer vision. It is a fascinating bridge between seeing an image and describing it in natural language, much like how we explain a photo to a friend. In this tutorial, I … Read more >>
Implementing RandAugment for Image Classification Keras is one of the best ways I have found to boost model robustness without the headache of manual hyperparameter tuning. I have spent many late nights adjusting individual augmentation values only to find that a simple, automated strategy like RandAugment often yields much better results for real-world applications. In … Read more >>
Preparing for a PyTorch interview can feel challenging, especially with so many technical topics to review. This article offers a structured way to study the core concepts, from tensor operations to advanced features like autograd and model optimization. It helps anyone strengthen their understanding of PyTorch fundamentals and demonstrate practical knowledge in real interview situations. … Read more >>
