A subtle selection bias in machine learning-based causal inference can flip your results — here’s how to spot and fix it Machine learning is great at predicting outcomes. But when we try to use it to estimate causal impact, especially in a two-stage setup,...
I spent months overengineering an AI chatbot. Then I threw most of it away and got better results in two weeks. This is an anecdote of what actually worked when I built production RAG systems at scale, and why the lessons surprised me. The Complexity Trap I was tasked...
Due to the recent advancements in artificial intelligence (AI) and machine learning (ML), organizations are increasing investments in information technology (IT) infrastructure that best supports automation enabled by AI and ML. While these automated systems can guide...
In the high-stakes world of IT infrastructure, the difference between a minor glitch and a major outage is often measured in minutes. Yet, for most organizations, the incident response lifecycle remains stuck in a manual era. As cloud environments grow...
