A promising alternative approach to improve forecasting Nikos Kafritsas · Follow Published in Towards Data Science · 8 min read · 7 hours ago — Image Source [1] The use of textual data to enhance forecasting performance isn’t new. In financial markets, text data and economic news often play a critical role in producing accurate forecasts — sometimes even more so than numeric historical data. Recently, many large language models (LLMs) have been fine-tuned on

The popular foundation time-series model just got an update Nikos Kafritsas · Follow Published in Towards Data Science · 9 min read · 15 hours ago — Image Source The race to build the Top foundation forecasting model is on! Salesforce’s MOIRAI, one of the early foundation models, achieved high benchmark results and was open-sourced along with its pretraining dataset, LOTSA. We extensively analyzed how MOIRAI works here — and built an end-to-end project comparing

And open-source as well! Nikos Kafritsas · Follow Published in Towards Data Science · 8 min read · 8 hours ago — A top-level view of Time-MOE (Image Source) The Mixture-of-Experts (MOE) architecture has surged in popularity with the rise of large language models (LLMs). As time-series models adopt cutting-edge techniques, Mixture-of-Experts has naturally found its place in the time-series foundation space. This article discusses Time-MOE, a time-series foundation model that uses MOE to improve
