SciPy gives you three doors into root finding, and picking the wrong one is why scipy.optimize.root feels awkward for simple problems. Most people land here with a single equation, so it’s one of the first two they want. I reach for brentq unless there’s a reason not to. Everything that follows was run on SciPy … Read more >>
Recently, I was working on a data science project where I needed to group similar data points. The challenge was finding an efficient way to perform hierarchical clustering and extract meaningful clusters from my dataset. That’s when I discovered SciPy’s fcluster function, a powerful tool that made this complex task surprisingly easy. In this article, … Read more >>
Recently, I was working on a machine learning project where I needed to calculate distances between multiple data points efficiently. The challenge was computing distances between two collections of inputs without writing nested loops. That’s when I discovered SciPy’s spatial distance cdist function. In this article, I’ll share how to use the cdist function to … Read more >>
Recently, I was working on a machine learning project where I needed to calculate distances between multiple data points. The challenge was finding an efficient way to compute these distances without writing complex loops. That’s when I discovered SciPy’s pairwise distance functionality. In this article, I’ll share how to use SciPy’s spatial distance functions to … Read more >>
Recently, I was working on a data analysis project that required dealing with noisy sensor data. The issue is that raw data often contains random fluctuations, which make it difficult to identify underlying patterns. So we need effective smoothing techniques. In this article, I’ll cover several simple ways you can use SciPy to smooth your … Read more >>
Recently, I was working on an image analysis project where I needed to read and manipulate images using Python. This is when I discovered the power of SciPy’s ndimage module and its imread function. The ndimage module offers a comprehensive suite of image processing tools, with imread being particularly useful for reading images as NumPy … Read more >>
When I was working on an optimization problem where I needed to find the global minimum of a complex function with multiple variables. Traditional optimization methods kept getting stuck in local minima, and I needed something more robust. That’s when I turned to SciPy’s differential evolution algorithm. In this article, I’ll walk you through how … Read more >>
linprog in SciPy solves linear programming problems: minimise a linear objective subject to linear constraints. Three things about it surprise people, and all three are in the first example: it only minimises, every variable is non-negative by default, and constraints must be written as <=. I solved each of these on SciPy 1.18.1 on Python … Read more >>
Recently, I was working on a machine learning project that involved a large dataset with mostly zero values. When I tried to process this data using regular NumPy arrays, my computer almost crashed due to memory limitations. That’s when I discovered the power of sparse matrices in SciPy, particularly the LIL (List of Lists) matrix … Read more >>
Recently, I was working on a data analysis project where I needed to estimate the probability density function of a dataset. The issue is, traditional histograms weren’t giving me the smooth representation I needed. This is where Gaussian Kernel Density Estimation (KDE) from SciPy came to the rescue. In this article, I’ll cover everything you … Read more >>
