Method, apparatus and computer program product for providing improved data compression

摘要

An apparatus for providing improved data compression may include an encoder comprising a quantizer for encoding input data and a side model. The quantizer may be trained with respect to high priority data among the input data and may be configured to partially encode the input data by encoding the high priority data. The side model may be trained jointly with the training of the quantizer and is configured to model low priority data among the input data.

1. A method comprising:
partially encoding, in a processor, input data by encoding high priority data among the input data using a quantizer trained with respect to the high priority data, wherein the high priority data is associated with a spectral envelope of the input data; and modeling, in a processor, low priority data among the input data using a side model trained jointly with the training of the quantizer, wherein the low priority data is associated with a residual spectrum of the input data, and wherein the low priority data is not quantized and not encoded.
