TimesFM 2.5

Overview

TimesFM 2.5 (Time Series Foundation Model) is a pretrained time-series foundation model proposed in A decoder-only foundation model for time-series forecasting by Abhimanyu Das, Weihao Kong, Rajat Sen, and Yichen Zhou. It builds on the original TimesFM architecture with rotary attention, QK normalization, per-dimension attention scaling, and continuous quantile prediction.

The abstract from the paper is the following:

Motivated by recent advances in large language models for Natural Language Processing (NLP), we design a time-series foundation model for forecasting whose out-of-the-box zero-shot performance on a variety of public datasets comes close to the accuracy of state-of-the-art supervised forecasting models for each individual dataset. Our model is based on pretraining a decoder style attention model with input patching, using a large time-series corpus comprising both real-world and synthetic datasets. Experiments on a diverse set of previously unseen forecasting datasets suggests that the model can yield accurate zero-shot forecasts across different domains, forecasting horizons and temporal granularities.

This model was contributed by kashif. The original code can be found here.

Usage example

python
import numpy as np
import torch

from transformers import TimesFm2_5ModelForPrediction


model = TimesFm2_5ModelForPrediction.from_pretrained(
    "google/timesfm-2.5-200m-transformers",
    device_map="auto",
)

forecast_input = [
    np.sin(np.linspace(0, 20, 100)),
    np.sin(np.linspace(0, 20, 200)),
    np.sin(np.linspace(0, 20, 400)),
]
forecast_input_tensor = [torch.tensor(ts, dtype=torch.float32, device=model.device) for ts in forecast_input]

with torch.no_grad():
    outputs = model(past_values=forecast_input_tensor, return_dict=True)
    point_forecast = outputs.mean_predictions
    quantile_forecast = outputs.full_predictions
