The main challenge that blocks the development of pre-trained model for time series analysis is the lack of a large amount of data for training. In this work, we address this challenge by leveraging language or CV models, pre-trained from billions of tokens, for time series analysis. Specifically, we refrain from altering the self-attention and feedforward layers of the residual blocks in the pre-trained language or image model.
The proposed method outperforms other models on most tasks, including long-term forecasting, short-term forecasting, classification, anomaly detection, imputation, and few-shot leanring, zero-short learning.
