MemCast: Memory-Driven Time Series Forecasting with Experience-Conditioned Reasoning

arXiv:2602.03164v2 Announce Type: replace Abstract: Time series forecasting (TSF) plays a critical role in decision-making for many real-world applications. Recently, large language model (LLM)- based forecasters have made promising advancements. Despite their effectiveness, existing methods often lack explicit experience accumulation and continual evolution. In this work, we propose MemCast, a learning-to-memory framework that reformulates TSF as an experience-conditioned reasoning task. Specifically, we learn experience from the training set and organize it into a hierarchical memory. This i

Why this matters
Why now

The proliferation of Large Language Models (LLMs) in various domains is driving continuous research into enhancing their capabilities for critical applications like time series forecasting.

Why it’s important

This development proposes a novel approach to time series forecasting, moving beyond current LLM limitations by integrating explicit experience accumulation and continual learning, which can significantly improve decision-making accuracy in real-world scenarios.

What changes

The explicit incorporation of 'experience-conditioned reasoning' into forecasting models marks a paradigm shift from purely data-driven or LLM-based approaches, potentially leading to more robust and adaptive predictions.
