When I build dashboards for financial analysis, I often need to compare two different metrics that don’t share the same scale. For instance, you might want to visualize the S&P 500 index price alongside the daily trading volume. If you plot them on the same Y-axis, the volume (in millions) will completely flatten the index … Read more >>
In my years of developing data-driven applications in Python, I’ve found that Matplotlib’s default scaling is usually great, but it isn’t perfect. There are many times when the default view starts the axis at a value that hides the trend you are trying to highlight. I often find myself needing to force a plot to … Read more >>
One of the most common challenges I face when building complex data visualizations is managing scales. Sometimes, a single Y-axis just doesn’t tell the whole story. In my experience, adding a secondary axis is the best way to compare two different data scales on a single chart. However, getting the range right can be tricky. … Read more >>
I have spent years visualizing complex datasets using Matplotlib, and one of the most common hurdles I see developers face is handling the axis range in imshow. By default, Matplotlib treats your array indices as coordinates, which rarely matches the real-world scale of your data. In this tutorial, I will show you exactly how to … Read more >>
Over my four years as a Keras developer, I have spent countless hours debugging backpropagation gradients. It is often frustrating when gradients vanish or explode during deep network training. Recently, I started experimenting with Geoffrey Hinton’s Forward-Forward (FF) algorithm as a powerful alternative. It replaces the traditional backward pass with two forward passes, one with … Read more >>
If you have been building vision models with Keras, you likely know that Self-Attention is the “gold standard” for capturing long-range dependencies. However, after four years of scaling these models, I have found that Self-Attention often struggles with high-resolution images because its complexity grows quadratically with the number of pixels. Recently, I started using Focal … Read more >>
I have spent the last four years building deep learning pipelines, and one thing is clear: Vision Transformers (ViT) are incredibly powerful but often too bulky for real-time applications. In this tutorial, I will show you how to use Keras to distill the knowledge from a large ViT model into a much smaller, faster neural … Read more >>
Training deep learning models that generalize well to real-world data can be a real challenge. In my four years of working with Keras, I’ve found that supervised consistency training is a game-changer for model stability. This technique ensures that your model produces similar predictions even when the input data undergoes slight variations or noise. In … Read more >>
I have spent a lot of time working with Keras and deep learning models. One of the most interesting challenges is training models when you do not have enough labeled data. In my experience, self-supervised learning is the best way to handle this. It allows the model to learn useful features from images without needing … Read more >>
In my years of developing deep learning solutions, I have often faced the challenge of having a mountain of data but only a tiny fraction of it labeled. It is a common headache when you are trying to deploy a model in a new environment where the data looks slightly different from your training set. … Read more >>
