We all know the usual Time Intelligence function based on years, quarters, months, and days. But sometimes, we need to perform more exotic timer intelligence calculations. But we should not forget to consider performance while programming the measures.  Introduction  There are many Dax functions in Power BI for Time Intelligence Measures.  The most common are:  You…

Introduction Data science is undoubtedly one of the most fascinating fields today. Following significant breakthroughs in machine learning about a decade ago, data science has surged in popularity within the tech community. Each year, we witness increasingly powerful tools that once seemed unimaginable. Innovations such as the Transformer architecture, ChatGPT, the Retrieval-Augmented Generation (RAG) framework, and state-of-the-art Computer Vision models — including GANs — have…

Which Outcome Matters? Here is a common scenario : An A/B test was conducted, where a random sample of units (e.g. customers) were selected for a campaign and they received Treatment A. Another sample was selected to receive Treatment B. “A” could be a communication or offer and “B” could be no communication or no…

Since founding Towards Data Science in 2016, we’ve built the largest publication on Medium with a dedicated community of readers and contributors focused on data science, machine learning, and AI. Medium built a fantastic platform, and we wouldn’t have been able to reach our audience without its help. As of Monday, February 3, 2025, Towards…

Insights from a synthetic control group Photo by Maria Ziegler on UnsplashReal estate is a bedrock of modern economies, serving as both a tangible asset and an essential component of wealth accumulation for individuals and investment portfolios. Real estate price fluctuations have far-reaching implications, influencing everything from consumer sentiment to financial stability. Understanding the drivers…

How Meta-CoT enhances system 2 reasoning for complex AI challenges Image created by the author using Generative AI (Flux-pro)What makes a language model smart? Is it predicting the next word in a sentence ‒ or handling tough reasoning tasks that challenge even bright humans? Today’s Large Language Models (LLMs) create smooth text plus solve simple…

Practical insights for a data-driven approach to model optimization Photo by Joshua Sortino on UnsplashIt is said that in order for a machine learning model to be successful, you need to have good data. While this is true (and pretty much obvious), it is extremely difficult to define, build, and sustain good data. Let me…

Data Science Explore the power of regex and save time in data analysis Image created by Author using Meta AIData is rarely clean and never in the required structure!! Whether you are starting with data science or are an experienced professional — You won’t deny the above statement! In a data analyst’s career extracting actionable…

Polynomial Fit in Python with NumPy Ball Tracking and Trajectory PredictionIn a previous project I visualized the trajectory of a ball that I threw vertically into the air with a real-time position, velocity and acceleration plot. Extending upon this project, I wanted to calculate and visualize a trajectory prediction based on a simple physics model.…
