TimeMachine

Welcome to the official repository of: TimeMachine: A Time Series is Worth 4 Mambas for Long-term Forecasting.

Usage

1. Install requirements. pip install -r requirements.txt

2. Navigate through our example scripts located at ./scripts/TimeMachine. You'll find the core of TimeMachine in models/TimeMachine.py. For example, to get the multivariate forecasting results for weather dataset, just run the following command, and you can open ./result.txt to see the results once the training is completed. Moreover, the results will also be available at csv_results, which can be utilized to make queries in the dataframe:

sh ./scripts/TimeMachine/weather.sh

Hyper-paramters can be tuned based upon needs (e.g. different look-back windows and prediction lengths). TimeMachine is built on the popular PatchTST framework.
