Abstract: This talk presents a novel generative probabilistic forecasting approach derived from the Wiener-Kallianpur innovation representation of nonparametric time series. In particular, we propose a weak innovation autoencoder architecture that transforms nonparametric multivariate random processes into canonical innovation sequences, from which future time series samples are generated according to conditional probability distribution on past samples. A novel deep-learning algorithm is proposed that constrains the latent process to be an independent and identically distributed sequence with matching input-output probability distributions of the autoencoder. We compare the proposed innovation-based forecasting with classic and leading machine-learning techniques, including some of the large language model-based forecasting techniques.
