Abstract
A computer system for performing negative sampling, including a processor chip having a plurality of on-chip memory banks, a plurality of on-chip compute engines and a memory interface, wherein the on-chip memory banks include memory blocks that store corresponding sets of 'likely to be updated' word vectors, a memory block that stores a subset of 'less likely to be updated' word vectors and a noise sample cache that stores a subset of negative samples. An external memory is coupled to the memory interface, and stores a set of ‘less likely to be updated’ word vectors and a set of negative samples. The on-chip compute engines include a refresh thread, which accesses the set of negative samples in the external memory to provide the subset of negative samples stored in the noise sample cache on the processor chip, such that these negative samples can be readily accessed on the processor chip.
