• Google’s New Explainable AI Service - 20 Dec 2019
  
  Google has started offering a new service for “explainable AI” or XAI, as it is fashionably called. Presently offered tools are modest, but the intent is in the right direction.
• Build Pipelines with Pandas Using pdpipe - 13 Dec 2019
  
  We show how to build intuitive and useful pipelines with Pandas DataFrame using a wonderful little library called pdpipe.
• Activation maps for deep learning models in a few lines of code - 10 Oct 2019
  
  We illustrate how to show the activation maps of various layers in a deep CNN model with just a couple of lines of code.
• Clustering Metrics Better Than the Elbow Method - 01 Oct 2019
  
  We show what metric to use for visualizing and determining an optimal number of clusters much better than the usual practice — elbow method.
• A Single Function to Streamline Image Classification with Keras - 23 Sep 2019
  
  We show, step-by-step, how to construct a single, generalized, utility function to pull images automatically from a directory and train a convolutional neural net model.
• Object-oriented programming for data scientists: Build your ML estimator - 30 Aug 2019
  
  Implement some of the core OOP principles in a machine learning context by building your own Scikit-learn-like estimator, and making it better.
• What is Benford’s Law and why is it important for data science? - 07 Aug 2019
  
  Benford’s law is a little-known gem for data analytics. Learn about how this can be used for anomaly or fraud detection in scientific or technical publications.
• How a simple mix of object-oriented programming can sharpen your deep learning prototype - 01 Aug 2019
  
  By mixing simple concepts of object-oriented programming, like functionalization and class inheritance, you can add immense value to a deep learning prototyping code.
• How do you check the quality of your regression model in Python? - 02 Jul 2019
  
  Linear regression is rooted strongly in the field of statistical learning and therefore the model must be checked for the ‘goodness of fit’. This article shows you the essential steps of this task in a Python ecosystem.
• Optimization with Python: How to make the most amount of money with the least amount of risk? - 26 Jun 2019
  
  Learn how to apply Python data science libraries to develop a simple optimization problem based on a Nobel-prize winning economic theory for maximizing investment profits while minimizing risk.
