Based on a new end-to-end adaptive large-scale distributed training technology , Baidu PaddlePaddle in Pengcheng cloud brain II Adaptive optimization on Cluster , Before training speed reaches optimization 2.1 times . And Pengcheng, the world's first knowledge enhancement model recently released - Baidu · Literary heart , It is also based on end-to-end adaptive large-scale distributed training technology .

Text task , From text processing 、 Training 、 Decoding to deployment for full acceleration . Upgrade support for string tensors , Provide end-to-end text task development experience for developers . In terms of the pre training model , in the light of Transformer Encoder The network structure realizes the ultimate performance optimization , And through the user-defined operator function , Integrated NVIDIA FasterTransformer High performance operator . Based on these optimizations , The framework forms a whole process development experience integrating training and promotion for the pre training model , Save deployment code 94%.

Hardware access , multi-level 、 The low-cost hardware adaptation scheme reduces the adaptation cost between the framework and the chip . Baidu self research Kernel Primitive API、NNAdapter、 compiler CINN( pre-release ) Three optimization schemes , Respectively for AI Operator Library 、 chart 、 Deep integration optimization of software and hardware at the back end of the compiler , The cost of hardware adaptation is greatly reduced , Enabling hardware ecosystem .

Continuously reduce the application threshold , Propeller model library 、 New upgrade of Enterprise Edition

In addition to the leading release of propeller deep learning framework technology , The summit also brought new upgrades to the industrial open source model library and enterprise version of the propeller .

Ma Yanjun said at the meeting , at present , Baidu PaddlePaddle's official support for the industrial open source algorithm model exceeds 400 individual , And publish 13 individual PP Series model , Achieve a balance in accuracy and performance , Completely open up the reasoning deployment tool chain .

While the application capacity of the propeller industry is comprehensively upgraded , The enterprise version of flying propeller is also focusing on improving the model deployment capability . At the meeting , Xinzhou has brought the deployment and upgrading of the model of the flying oar enterprise version and the flying oar EsayDL New release of desktop version .

Propeller enterprise edition includes EasyDL and BML Dual platform development mode , Committed to improving AI Development efficiency and resource utilization efficiency , At present, it has become the most widely used AI Development platform . The new upgrade of the model deployment is based on the propeller reasoning deployment tool chain , Deep integration with platform , Create automated and efficient enterprise deployment capabilities .

The first is automatic model combination compression , Significantly improve reasoning performance . be based on PaddleSlim, According to the characteristics of different models and hardware , Several fully automatic combined compression pipelines are designed , Can automatically select the best compression path . For common models , Accuracy loss control in 1% Next , The acceleration ratio can reach 3-5 times .

Secondly, based on the propeller reasoning engine , Widely adaptive reasoning chip . The new version uses a propeller inference engine , It is widely adapted to reasoning chips and has excellent performance . at present , Platform completed 9345 Real test and tuning of a combination of model chips , You can override 95% Demand scenarios for , Savings compared to self adaptation 97% Development time of .

Finally, model service and intelligent edge console , Significantly improve deployment efficiency . Especially the newly released intelligent edge console , It provides a fully visual operation interface , The efficiency of model and business integration is significantly improved , Model deployment time has been reduced from days to 5 minute . Xinzhou demonstrated how to 5 Minutes to let the robot dog learn new skills of gesture recognition .

Last , Flying propeller EasyDL The desktop version is newly released . Developers don't have to configure all kinds of environments , High efficiency local modeling can be achieved by one click high-speed installation on the desktop ,1 Minutes to install ,15 Model development can be completed in minutes , Local data management 、 Computing power scheduling 、 Deploy the application , Give Way AI“ You can get ”.

Baidu PaddlePaddle's industrial deep learning open source open platform originated from industrial practice , It is Baidu's practice of integration and innovation 、 Reducing the threshold of industry development AI Mass production platform . Iterative updates from generation to generation of the propeller , It is also a step-by-step upward climb of China's artificial intelligence industry .AI Promote China's industrial prosperity , The oars have been on the road .
