TEMPO: Prompt-based Generative Pre-trained Transformer for Time Series Forecasting

preprint

The official code for ["TEMPO: Prompt-based Generative Pre-trained Transformer for Time Series Forecasting (ICLR 2024)"]. TEMPO is one of the very first open source Time Series Foundation Models for forecasting task v1.0 version.

💡 Demos

1. Reproducing zero-shot experiments on ETTh2:

Please try to reproduc the zero-shot experiments on ETTh2 [here on Colab].

2. Zero-shot experiments on customer dataset:

We use the following Colab page to show the demo of building the customer dataset and directly do the inference via our pre-trained foundation model: [Colab]

🔧 Hands-on: Using Foundation Model

1. Download the repo

git clone git@github.com:DC-research/TEMPO.git

2. [Optional] Download the model and config file via commands

huggingface-cli download Melady/TEMPO config.json --local-dir ./TEMPO/TEMPO_checkpoints

huggingface-cli download Melady/TEMPO TEMPO-80M_v1.pth --local-dir ./TEMPO/TEMPO_checkpoints

huggingface-cli download Melady/TEMPO TEMPO-80M_v2.pth --local-dir ./TEMPO/TEMPO_checkpoints

3. Build the environment

conda create -n tempo python=3.8

conda activate tempo

cd TEMPO

pip install -r requirements.txt

4. Script Demo

A streamlining example showing how to perform forecasting using TEMPO:

python

# Third-party library imports
import numpy as np
import torch
from numpy.random import choice
# Local imports
from models.TEMPO import TEMPO


model = TEMPO.load_pretrained_model(
        device = torch.device('cuda:0' if torch.cuda.is_available() else 'cpu'),
        repo_id = "Melady/TEMPO",
        filename = "TEMPO-80M_v1.pth",
        cache_dir = "./checkpoints/TEMPO_checkpoints"  
)

input_data = np.random.rand(336)    # Random input data
with torch.no_grad():
        predicted_values = model.predict(input_data, pred_length=96)
print("Predicted values:")
print(predicted_values)

5. Online demo

Please try our foundation model demo [here].

🔨 Advanced Practice: Full Training Workflow!

We also updated our models on HuggingFace: [Melady/TEMPO].

1. Get Data

Download the data from [Google Drive] or [Baidu Drive], and place the downloaded data in the folder./dataset. You can also download the STL results from [Google Drive], and place the downloaded data in the folder./stl.

2. Run Scripts

2.1 Pre-Training Stage

bash [ecl, etth1, etth2, ettm1, ettm2, traffic, weather].sh

2.2 Test/ Inference Stage

After training, we can test TEMPO model under the zero-shot setting:

bash [ecl, etth1, etth2, ettm1, ettm2, traffic, weather]_test.sh

Pre-trained Models

You can download the pre-trained model from [Google Drive] and then run the test script for fun.

TETS dataset

Here is the prompts use to generate the coresponding textual informaton of time series via [OPENAI ChatGPT-3.5 API]

The time series data are come from [S&P 500]. Here is the EBITDA case for one company from the dataset:

Example of generated contextual information for the Company marked above:

You can download the processed data with text embedding from GPT2 from: [TETS].

🚀 News
