Creating a visual representation of data over time is one of the most common tasks I handle as a Python developer. Whether I am tracking quarterly revenue or monitoring weather patterns in different US states, a time series bar plot is often my go-to choice. In this tutorial, I will show you exactly how to … Read more >>
I’ve found that a single line chart often hides the most important parts of a story. When you are dealing with time series data, showing just the average or the trend line isn’t enough to see the full picture. You often need to see the “spread” or the volatility of that data over specific intervals, … Read more >>
Visualizing data over time is a task I perform almost daily as a developer. While line charts are the standard, there are many times when a scatter plot is actually the better choice. In my experience, scatter plots are perfect for identifying outliers in time-based data or showing specific events that don’t necessarily have a … Read more >>
In my years of building data dashboards for US-based financial firms, I’ve realized that Matplotlib’s default scaling isn’t always perfect. Sometimes, the auto-scaling feature hides the small differences between data points that actually matter for your analysis. In this tutorial, I will show you exactly how to take control of your Y-axis limits to make … Read more >>
Visualizing data with massive variations can be quite a headache. I often find that a standard linear scale makes small values disappear while large values hog the entire chart. In my experience, switching to a logarithmic scale is the best way to solve this. It allows you to see the percentage change and growth patterns … Read more >>
Dynamic data visualization is a skill I frequently utilize, particularly when tracking real-time trends or simulating movements. In my experience, static plots often fail to tell the whole story, particularly when you need to see how data points evolve. I have spent many hours refining the process of refreshing plots efficiently without crashing the backend … Read more >>
I have spent the last four years building deep learning models, and if there is one thing I have learned, it is that standard Convolutional Neural Networks (ConvNets) sometimes miss the “big picture.” While convolutions are great at picking up local patterns, they often struggle to understand which parts of an image are truly important … Read more >>
I’ve found that scaling Vision Transformers (ViT) often leads to significant training instability. Standard ViT architectures tend to saturate or diverge when you add too many layers, which can be quite frustrating during model development. Recently, I started using Class Attention Image Transformers (CaiT), which introduces LayerScale to handle these deep architectural challenges effectively. In … Read more >>
I have often noticed a frustrating drop in accuracy when deploying models. You train a model on $224 \times 224$ images, but the real-world performance only peaks when you feed it larger images during inference. This phenomenon is known as the train-test resolution discrepancy, and it occurs because the statistics of the data change when … Read more >>
I have spent a significant amount of time building complex deep learning models that perform brilliantly but are far too heavy for mobile devices. In my experience, Knowledge Distillation is the most effective way to shrink a massive “Teacher” model into a compact “Student” model while keeping the accuracy high. In this tutorial, I will … Read more >>
