Improving Multi-Step Prediction of Learned Time Series Models

arXiv 2015 31.5 method

TLDR

A method improving multi-step time series prediction using imitation learning with theoretical guarantees, tested on dynamic systems and video textures.

Reasoning

The paper presents a novel reduction of multi-step prediction to imitation learning, providing a theoretical guarantee and empirical improvements in two domains. However, the scope is limited to time series and does not explicitly address world models or simulation, which may reduce relevance to those keywords.
