The TensorFlow Model Optimization Toolkit is a suite of tools for optimizing ML models for deployment and execution. Among many uses, the toolkit supports techniques used to:
- Reduce latency and inference cost for cloud and edge devices (e.g. mobile, IoT).
- Deploy models to edge devices with restrictions on processing, memory, power-consumption, network usage, and model storage space.
- Enable execution on and optimize for existing hardware or new special purpose accelerators.
Choose the model and optimization tool depending on your task:
Improve performance with off-the-shelf modelsIn many cases, pre-optimized models can improve the efficiency of your application.
