Chronos Forecasting

Chronos-forecasting is a zero-shot time series forecasting framework based on a pretrained large language model. It enables the prediction of future values across diverse datasets without requiring task-specific training or optimization.

The system functions as a probabilistic forecasting tool, producing multiple future trajectories and quantile forecasts to quantify uncertainty and potential prediction errors. It incorporates exogenous covariate integration to merge external variables and historical context into the input stream for increased precision.

The project includes utilities for synthetic time series generation to benchmark models and train algorithms, as well as tools for forecast accuracy evaluation using standardized error metrics. It also provides capabilities for tuning model weights and parameters to improve accuracy for specific data patterns.

Features

  • LLM-Based Forecasting - Adapts a pretrained transformer architecture to treat time series values as discrete tokens for forecasting.
  • Probabilistic Forecasting - Produces value ranges and uncertainty intervals through quantile forecasts rather than simple point estimates.
  • Zero-Shot Forecasting - Predicts future values for diverse time series using pretrained models without requiring task-specific training.
  • Probabilistic Generative Sampling - Generates a distribution of future outcomes by repeatedly sampling from the model's learned probability distribution.
  • Supervised Model Weight Optimization - Updates model parameters using specific datasets and configurations to improve prediction accuracy.
  • Dynamic Covariate Integration - Incorporates time-varying external features and known future events to improve the precision of time series forecasts.
  • Time Series Model Tuning - Allows adjusting model weights and parameters on specific datasets to increase accuracy for unique data patterns.
  • Uncertainty Estimation - Quantifies prediction error margins by producing multiple future trajectories through model sampling.
  • Time Series Foundation Models - Learns the language of time series for forecasting.
  • Time Series Analysis - Probabilistic time series forecasting using language models.
