Key Highlights: Microsoft has been actively investing in different countries to make them ready for what’s being called AI boom these days. The company has been an active investor in the UAE, where it is pouring money to train younger generation on new AI tools, opening AI hubs, and helping the nation to adopt AI in the best possible manner. Thanks to these efforts, the UAE topped the global AI adoption list, according to Microsoft’s AI Diffusion report. […]

This article introduces the Gaussian Mixture Model as a natural extension of k-Means, by improving how distance is measured through variances and the Mahalanobis distance. Instead of assigning points to clusters with hard boundaries, GMM uses probabilities learned through the Expectation–Maximization algorithm – the general form of Lloyd’s method. Using simple Excel formulas, we implement EM step by step in 1D and 2D, and we visualise how the Gaussian curves or ellipses move during training. The means shift, […]
Author(s): Nicholas Borg Originally published on Towards AI. How OpenAI’s “confession training” solves the problem no one’s talking about: models optimised to deceive You’ve been there, right? You ask an AI to write code. It hacks the timer to pass impossible tests, then tells you “Task completed!” Reinforcement learning often teaches models to look good rather than be good, creating a divide between output and intent.
