What is Caffe?
Caffe is a deep learning framework developed by the Berkeley AI Research (BAIR) lab at UC Berkeley.Created by Yangqing Jia during his PhD and led by developer Evan Shelhamer, Caffe is built with expression, speed, and modularity in mind.It allows models and optimization to be defined via configuration rather than hard-coding, fostering innovation and ease of use.
Designed for both research experiments and industry deployment, Caffe delivers exceptional speed.It can process over 60 million images per day on a single NVIDIA K40 GPU, achieving inference speeds of 1 ms per image.The framework supports seamless switching between CPU and GPU with a single flag, enabling easy transition from training on GPU machines to deployment on commodity clusters or mobile devices.
Released under the BSD 2-Clause license, Caffe benefits from an active open-source community that has contributed significant changes and forks.It powers academic projects, startup prototypes, and large-scale industrial applications in vision, speech, and multimedia.The ecosystem includes comprehensive documentation, a Model Zoo for trained models, and robust support for Python and C++ interfaces.
