- 20. Amazon Confidential Tensorflow • Multi-machinemulti-GPU • Broad language support • Automatic parallelization (see compute graph) • Mobile device support
- 21. Amazon Confidential Caffe -Deep Learning Framework by the BVLC Caffe is a deep learning framework made with expression, speed, and modularity in mind. It is developed by the Berkeley Vision and Learning Center (BVLC) and by community contributors. Yangqing Jia created the project. • Expressive architecture encourages application and innovation. Models and optimization are defined by configuration without hard- coding. Switch between CPU and GPU by setting a single flag. • Supports multiple GPUs but not multiple machines. • Caffe on Spark and Caffe con Troll are some attempts to scale it. • Community. Caffe powers academic research projects, startup prototypes, and large-scale industrial applications in vision, speech, and multimedia.
- 22. Amazon Confidential Torch Torch isa scientific computing framework with wide support for machine learning algorithms that puts GPUs first. It is easy to use and efficient, thanks to an easy and fast scripting language, LuaJIT, and an underlying C/CUDA implementation. • powerful N-dimensional array • lots of routines for indexing, slicing, transposing, ... • amazing interface to C, via LuaJIT • linear algebra routines • neural network, and energy-based models • numeric optimization routines • Fast and efficient GPU support • Embeddable, with ports to iOS, Android and FPGA backends
