1. A method comprising:
obtaining a stream of input vectors to be compressed;
for each of the input vectors:
determining a distance between the input vector to be compressed and each codeword of a plurality of codewords; and
selecting two or more codewords of the plurality of codewords based on the distance between the input vector to be compressed and each of the two or more codewords; and
generating compressed data that comprises an indication of the two or more codewords of the plurality of codewords.
