Abstract:
1. An embedded dead zone plus uniform threshold quantizer executing in memory of a computing system, wherein the quantizer is characterized by integers m and n, wherein m is greater than or equal to 0, wherein n is greater than or equal to 0, wherein m is not equal to n, wherein the quantizer includes a rule for processing information in an embedded representation at plural levels, wherein for each of the plural levels the quantizer has a dead zone in the level and plural non-dead zones in the level, wherein for each of the plural levels the quantizer uses clipping to limit range of classification regions in the level, wherein the range for the clipping varies between the plural levels, and wherein according to the rule for each level of one or more of the plural levels: each of at least some of the plural non-dead zones in the level splits into m+1 non-dead zones in a higher level; and the dead zone in the level splits into a dead zone and n non-dead zones on each side in the higher level.
