Meta’s upcoming ‘Avocado’ AI model could be a part of effort to rebalance its open-source vision
Key Highlights: Meta is among the few tech giants that advocate open-source AI (like its Llama models) for innovation, security through community testing, cost-effectiveness for businesses, and preventing gatekeeping. But it seems Meta has realized the future with open-source AI isn’t worth it, as that goodwill won’t pay the bills for its $600 billion investment pledge in the US infrastructure.

The Machine Learning “Advent Calendar” Day 11: Linear Regression in Excel
Linear Regression looks simple, but it introduces the core ideas of modern machine learning: loss functions, optimization, gradients, scaling, and interpretation. In this article, we rebuild Linear Regression in Excel, compare the closed-form solution with Gradient Descent, and see how the coefficients evolve step by step. This foundation naturally leads to regularization, kernels, classification, and the dual view. Linear Regression is not just a straight line, but the starting point for many models we will explore next in […]

With a simple one-feature dataset, we can see how a tree chooses its first split. The idea is always the same: if humans can guess the split visually, then we can rebuild the logic step by step in Excel. By listing all possible split values and computing the MSE for […]
