... discounting, is approximately 1.0, their mean quantization error would be approximately 0.5. We also try setting δ by optimization on held-out data. 4 Evaluation and Conclusions We trained and ... interpolation with lower-order estimates, which should have lower quantization error, due to higher context counts. As we have noted, most ex- isting interpolation models are constrained so that...
