@@ -8,8 +8,8 @@ The fixed-point model has many advantages over the fp32 model:
 - Benefit from the smaller model, the Cache hit rate is improved and inference would be faster
 - Chips tend to have corresponding fixed-point acceleration instructions which are faster and less energy consumed (int8 on a common CPU requires only about 10% of energy)
 
-The size of the installation package and the heat generation are the key indicators of the mobile terminal evaluation APP;
-On the server side, quantization means that you can maintain the same QPS and improve model precision in exchange for improved accuracy.

 Calibration set is used to calculate quantization layer parameters. Some DFQ (Data Free Quantization) methods do not even require a dataset.
