📖 Full Retelling
Researchers have introduced the LTSM-Bundle, a comprehensive toolbox and benchmark for Large Language Models applied to Time Series Forecasting, as detailed in their latest arXiv submission (2406.14045v3) released in June 2024. This development comes in response to the growing challenges in Time Series Forecasting (TSF), a complex field that has long struggled with diverse data patterns. The LTSM-Bundle aims to facilitate the development and evaluation of Large Time Series Models (LTSMs), which are transformer-based architectures leveraging autoregressive prediction techniques to improve forecasting accuracy. These models face significant hurdles when trained on heterogeneous time series data characterized by varying frequencies, dimensions, and patterns across different datasets. The toolbox provides researchers with standardized tools and benchmarks to address these challenges systematically, potentially accelerating advancements in the field of time series analysis.

A large language model (LLM) is a language model trained with self-supervised machine learning on a vast amount of text, designed for natural language processing tasks, especially language generation. The largest and most capable LLMs are generative pre-trained transformers (GPTs) that provide the c...
In mathematics, a time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data.

Abstract: Time Series Forecasting (TSF) has long been a challenge in time series analysis. Inspired by the success of Large Language Models (LLMs), researchers are now developing Large Time Series Models (LTSMs)-universal transformer-based models that use autoregressive prediction-to improve TSF. However, training LTSMs on heterogeneous time series data poses unique challenges, including diverse frequencies, dimensions, and patterns across dataset
