· 12/03/2025
20/30 AAII Impact Score

AI Summary: The article presents an analysis of inflation expectations using three time series methods: moving averages, year-over-year changes, and Bollinger Bands, applied to the 5-year inflation data trend from October 2020 to October 2025. The analysis focuses on the 10-Year Breakeven Inflation Rate (T10YIE), which reflects market expectations for inflation over the next decade. Each method provides distinct insights: moving averages reveal trend direction, year-over-year changes indicate momentum shifts, and Bollinger Bands highlight periods of extreme movement. The dataset consists of 1,305 daily observations sourced from the Federal Reserve Economic Data (FRED).

The Machine Learning “Advent Calendar” Day 5: GMM in Excel

· 12/05/2025
Research Computer ScienceMathematical Sciences

AI Summary: The article discusses the Gaussian Mixture Model (GMM) as an unsupervised learning counterpart to Quadratic Discriminant Analysis (QDA), emphasizing its reliance on both mean and variance to describe clusters. It highlights the historical context of model naming in machine learning, noting that many models, including GMM, originated from statistics and other fields before being integrated into machine learning. The article also explains the relationship between GMM and K-Means, illustrating how GMM can be viewed as grouping data by Gaussian shapes rather than centroids. Additionally, it introduces the Expectation-Maximization (EM) algorithm as a generalization of Lloyd's algorithm, which is used for training GMMs.
