May 07, 2019 · With a bit of familiarity with TensorFlow and an understanding of how to use tools like Firebase’s ML Kit, you can fairly easily create custom machine learning models for mobile devices. Imagine in-app stock suggestions, on-device medical imaging, or ML-powered photo/video editors. In this talk we’ll cover techniques to do post-training quantization that can improve model accuracy for 8-bit quantization significantly. These techniques are especially useful when training/fine-tuning is not possible, as case that arises very frequently in commercial applications.

3 Quantization Procedure An ideal quantization procedure for CNNs is one that with little effort can be made backwards compatible with existing hardware and software. Additionally, it is preferential to be able to reuse existing models to save the time of training from scratch, as featured in Ristretto [10, 11] and Google’s TensorFlow [17]. .
