Fabric for Deep Learning (FfDL) vs. Caffe

Deep learning frameworks such as TensorFlow, PyTorch, Caffe, Torch, Theano, and MXNet have greatly improved the ease with which deep learning models can be designed, trained, and utilized. Fabric for Deep Learning (FfDL, pronounced "fiddle") provides a unified approach for deploying these deep-learning frameworks as a service on Kubernetes, facilitating seamless functionality. The FfDL architecture is constructed using microservices, which reduces the reliance between components, enhances simplicity, and ensures that each component operates in a stateless manner. This architectural choice is advantageous as it allows failures to be contained and promotes independent development, testing, deployment, scaling, and updating of each service. By leveraging Kubernetes' capabilities, FfDL creates an environment that is highly scalable, resilient, and capable of withstanding faults during deep learning operations. Furthermore, the platform includes a robust distribution and orchestration layer that enables efficient processing of extensive datasets across several compute nodes within a reasonable time frame. Consequently, this thorough strategy guarantees that deep learning initiatives can be carried out with both effectiveness and dependability, paving the way for innovative advancements in the field.

Caffe is a robust deep learning framework that emphasizes expressiveness, efficiency, and modularity, and it was developed by Berkeley AI Research (BAIR) along with several contributors from the community. Initiated by Yangqing Jia during his PhD studies at UC Berkeley, this project operates under the BSD 2-Clause license. An interactive web demo for image classification is also available for exploration by those interested! The framework's expressive design encourages innovation and practical application development. Users are able to create models and implement optimizations using configuration files, which eliminates the necessity for hard-coded elements. Moreover, with a simple toggle, users can switch effortlessly between CPU and GPU, facilitating training on powerful GPU machines and subsequent deployment on standard clusters or mobile devices. Caffe's codebase is highly extensible, which fosters continuous development and improvement. In its first year alone, over 1,000 developers forked Caffe, contributing numerous enhancements back to the original project. These community-driven contributions have helped keep Caffe at the cutting edge of advanced code and models. With its impressive speed, Caffe is particularly suited for both research endeavors and industrial applications, capable of processing more than 60 million images per day on a single NVIDIA K40 GPU. This extraordinary performance underscores Caffe's reliability and effectiveness in managing extensive tasks. Consequently, users can confidently depend on Caffe for both experimentation and deployment across a wide range of scenarios, ensuring that it meets diverse needs in the ever-evolving landscape of deep learning.
