mgl provides a machine learning library in Common Lisp, including neural networks and Gaussian processes.
Bender
Bender helps developers build neural networks for iOS using TensorFlow models and Metal.

About Bender
Bender is an open-source iOS framework that provides an abstraction layer over MetalPerformanceShaders to simplify building and running neural networks on iOS devices. It is designed to execute pretrained neural networks on iOS without requiring inclusion of TensorFlow's static library in projects. The framework supports defining custom neural networks with common layers including convolution, pooling, fully connected, and normalization layers, and includes an adapter to import models trained in TensorFlow, though this adapter currently supports only a subset of TensorFlow operations. Bender requires Xcode 9 for development and has a deployment target of iOS 10.0, supporting iOS 11.0 and above for runtime features.
