Abstract (en)

[origin: WO2021001594A1] Example embodiments provide a neural data compression network which may be configured to output variable bit rate codes and a decompression network capable of decompressing the variable bit rate codes. This is achieved based on training an encoder network to be capable of outputting variable size activations. Output activations may be divided into a plurality of blocks and a subset of the blocks may be selected based on a desired quality level. A decoder network may be trained as part of an auto-encoder comprising the encoder network. Apparatuses, methods, and computer programs are disclosed.
