Today, give a try to Techtonique web app, a tool designed to help you make informed, data-driven decisions using Mathematics, Statistics, Machine Learning, and Data Visualization. Here is a tutorial with audio, video, code, and slides: https://moudiki2.gumroad.com/l/nrhgb
Last week, I presented a new version of ahead, which includes an extension of the Theta forecasting method to Generalized Linear Models (GLMs), GAMs, GLMBoost, and an attention mechanism (work in progress).
This post demonstrates the performance of the new method on Tourism (1311 series), M1 (1001 series), M3 (3003 series), and M4 Yearly (23000 series) competition data sets. Workhorse models are used to benchmark the new method, including glm.nb, glm, rlm, lqs, gam, and glmboost.
The results are compared to the original Theta method, and are highly competitive, especially on the Tourism and M4 Yearly data sets (MASE, RMSE).
