Welcome to the world of TinyTimeMixers (TTM)! These compact pre-trained models created by IBM Research are here to bring a new revolution in the field of multivariate time-series forecasting. If you’re ready to embark on this journey, you’re in the right place!

What is TinyTimeMixer?

TinyTimeMixers (TTMs) are innovative, pre-trained models designed for time-series forecasting with less than 1 million parameters. Think of them as sleek race cars in the world of forecasting, outperforming much larger, bulkier models while using significantly fewer resources. They excel at zero-shot and few-shot forecasting, even when compared to heavyweights with hundreds of millions of parameters.

How to Get Started with TTM

Getting started with TTM is as easy as pie! Here’s how you can kick off your forecasting endeavor:

• Getting Started Notebook
• 512-96 Benchmarks
• 1024-96 Benchmarks

Tips for Using TTM Effectively

To make the most out of TTM, keep the following tips in mind:

1. Standard scale your data independently for every channel before feeding it to the model. Use the TSP utility for scaling.
2. TTM currently supports only minutely and hourly resolutions, e.g., 10 min, 15 min, 1 hour. It does not support lower resolutions as these require a minimum context length of 512 or 1024.
3. Avoid enabling any upsampling or prepending zeros to data, as it can adversely impact model performance.

Understanding TTM’s Performance

Imagine using a small, agile drone to scout a large area instead of a gigantic blimp. The drone, while small, is nimble and collects data efficiently, just like TTM outperforms larger models in time-series forecasting. Utilizing only a fraction of the parameters, TTM still manages to provide stellar predictions:

• TTM achieved a remarkable 24% improvement over LLMTime (from NeurIPS 23) in zero-shot forecasting.
• Boasting fast inferencing & fine-tuning times, TTM takes just minutes on a single GPU, while others take considerably longer.

Troubleshooting & Common Issues

If you run into issues while implementing TTM, don’t worry! Here are some troubleshooting tips:

• Ensure your data is properly scaled. Failing to standardize the data can lead to inaccurate forecasts.
• Check if you are using the correct context length for your desired forecast. Shorter contexts might produce suboptimal results.
• Always refer to the latest version of the paper for updated benchmarks and configurations.
