Before revision:  For both cases, with an 8-bit integer-only quantization scheme, I-BERT achieves similar  accuracy as compared to the full-precision baseline  .
After revision:  For both cases, with an 8-bit integer-only quantization scheme, I-BERT achieves similar accuracy as compared to the full-precision baseline . Furthermore, our preliminary implementation of I-BERT shows a speedup of 2.4 - 4.0x for INT8 inference on a T4 GPU system as compared to FP32 inference. The framework has been developed in PyTorch and has been open-sourced .
