class gluonts.model.deepstate.issm.ISSM[source]#

Bases: object

An abstract class for providing the basic structure of Innovation State Space Model (ISSM).

The structure of ISSM is given by

  • dimension of the latent state

  • transition and innovation coefficients of the transition model

  • emission coefficient of the observation model
