Abstract:
1. A method for compressing quantized vector data into compressed bytes, the method comprising: obtaining the quantized vector data comprising first integers; generating a first chain from at least a portion of the quantized vector data; generating at least one additional chain that branches from the first chain; storing the at least one additional chain as at least one array of second integers, wherein at least a portion of the second integers is closer to zero than the first integers; selecting a most suitable algorithm from a plurality of algorithms for compressing the at least one additional chain, wherein selecting the most suitable algorithm for compressing the at least one additional chain comprises: compressing, by a computer, the at least one additional array of second integers into the compressed bytes according to the most suitable algorithm; and generating a flag indicating which of the plurality of algorithms to be applied at decompression of the compressed bytes.
