Revealing Scaling Behavior in Large-scale Time Series Models: Implications for More Efficient and Accurate Forecasting
Large-scale models are at the forefront of time series (TS) forecasting, dominated by two paradigms: fine-tuning text-based Large Language Models for TS (LLM4TS) and training Time Series Foundation Models (TSFMs) from scratch. Both approaches share a foundational assumption that scaling up model cap…
