What is chronos-bolt-small?
Chronos-bolt-small is a powerful time series forecasting model that belongs to the innovative Chronos-Bolt family. Built on the T5 encoder-decoder architecture, this model represents a significant advancement in time series analysis, having been trained on nearly 100 billion time series observations. What sets it apart is its ability to perform zero-shot forecasting while being dramatically more efficient than its predecessors.
Implementation Details
The model operates by chunking historical time series data into observation patches that are processed by the encoder. The decoder then utilizes these representations to generate quantile forecasts across multiple future steps through direct multi-step forecasting. This implementation results in performance that is up to 250 times faster and 20 times more memory-efficient than the original Chronos models.
