Embedding Compression with Isotropic Iterative Quantization
Table 4: Topic Classification Results.
['[EMPTY]', '[BOLD] Method', '[BOLD] CR', '[BOLD] MPQA', '[BOLD] MR', '[BOLD] SUBJ']
Similar to the previous tasks, the proposed IIQ method consistently performs better than ITQ, pruning, and DCCL. The only exception is that for MPQA and SUBJ, DCCL and NLB achieves the best result for the GloVe embedding respectively. As the compression ratio increases, IIQ encounters performance degrade.
