Abstract: A data encoding method includes obtaining to-be-encoded data; processing the to-be-encoded data by using a volume preserving flow model to obtain a hidden variable output, where the volume preserving flow model includes a target volume preserving flow layer, an operation corresponding to the target volume preserving flow layer is an invertible operation that meets a volume preserving flow constraint, the target volume preserving flow layer is used to perform a multiplication operation on a preset coefficient and first data input to the target volume preserving flow layer, and the preset coefficient is not 1; and encoding the hidden variable output to obtain encoded data.
