5 Common Mistakes in Machine Learning and How to Avoid Them

Image by Author Using machine learning to solve real-world problems is exciting. But most eager beginners jump straight to model building—overlooking the fundamentals—resulting in models that aren’t very helpful. From understanding the data to choosing the best machine learning model for the problem, there are some common mistakes that beginners often tend to make. But before we go over them, you should understand the problem—it is step 0 if you will—you are trying to solve. Ask yourself enough questions to […]

Defining Python Constants for Code Maintainability

In programming, the term constant refers to names representing values that don’t change during a program’s execution. Constants are a fundamental concept in programming, and Python developers use them in many cases. However, Python doesn’t have a dedicated syntax for defining constants. In practice, Python constants are just variables that never change. To prevent programmers from reassigning a name that’s supposed to hold a constant, the Python community has adopted a naming convention: use uppercase letters. For every Pythonista, it’s […]

GraphRAG: New tool for complex data discovery now on GitHub

Earlier this year, we introduced GraphRAG (opens in new tab), a graph-based approach to retrieval-augmented generation (RAG) that enables question-answering over private or previously unseen datasets. Today, we’re pleased to announce that GraphRAG is now available on GitHub (opens in new tab), offering more structured information retrieval and comprehensive response generation than naive RAG approaches. The GraphRAG code repository is complemented by a solution accelerator (opens in new tab), providing an easy-to-use

Understanding the Python Mock Object Library

Python’s unittest.mock library is a tool that helps you create mock objects to simulate complex logic and unpredictable dependencies. This helps you write valuable tests that verify your application logic is correct, reliable, and efficient. You’ll begin by learning about what mocking is and how you can use it to improve your tests. What Is Mocking? A mock object substitutes and imitates a real object within a testing environment. Using mock objects is a versatile and powerful way to improve […]
