Awesome TensorFlow Lite

TensorFlow Lite is a set of tools that help convert and optimize TensorFlow models to run on mobile and edge devices. It’s currently running on more than 4 billion devices! With TensorFlow 2.x, you can train a model with tf.Keras, easily convert a model to .tflite and deploy it; or you can download a pretrained TensorFlow Lite model from the model zoo.

This is an awesome list of TensorFlow Lite models with sample apps, helpful tools and learning resources -

• Showcase what the community has built with TensorFlow Lite
• Put all the samples side-by-side for easy reference
• Share knowledge and learning resources

Past announcements:

Here are some past feature annoucements of TensorFlow Lite:

• Announcement of the new converter - MLIR-based and enables conversion of new classes of models such as Mask R-CNN and Mobile BERT etc., supports functional control flow and better error handling during conversion. Enabled by default in the nightly builds.
• Android Support Library - Makes mobile development easier (Android sample code).
• Model Maker - Create your custom image & text classification models easily in a few lines of code. See below the Icon Classifier for a tutorial by the community.
• On-device training - It is finally here! Currently limited to transfer learning for image classification only but it’s a great start. See the official Android sample code and another one from the community (Blog | Android).
• Hexagon delegate - How to use the Hexagon Delegate to speed up model inference on mobile and edge devices. Also see blog post Accelerating TensorFlow Lite on Qualcomm Hexagon DSPs.
• Model Metadata - Provides a standard for model descriptions which also enables Code Gen and Android Studio ML Model Binding.
