The 1st EMC2 - Energy Efficient Training and Inference of Transformer Based Models
Co-located with the 23rd ACM International Conference on Architectural Support for Programming Languages and Operating Systems ASPLOS 2018
description Workshop Objective
Transformers are the foundational principles of large deep learning language models. Recent successes of Transformer-based models in image classification and action prediction use cases indicate their wide applicability. In this workshop, we want to focus on the leading ideas using Transformer models such as PALM from Google. We will learn what have been their key observations on performance of the model, optimizations for inference and power consumption of both mixed-precision inference and training.
chat Call for Papers
The goal of this Workshop is to provide a forum for researchers and industry experts who are exploring novel ideas, tools, and techniques to improve the energy efficiency of machine learning and deep learning as it is practiced today and would evolve in the next decade. We envision that only through close collaboration between industry and the academia we will be able to address the difficult challenges and opportunities of reducing the carbon footprint of AI and its uses. We have tailored our program to best serve the participants in a fully digital setting. Our forum facilitates active exchange of ideas through:
- Keynotes, invited talks and discussion panels by leading researchers from industry and academia
- Peer-reviewed papers on latest solutions including works-in-progress to seek directed feedback from experts
- Independent publication of proceedings through IEEE CPS
We invite full-length papers describing original, cutting-edge, and even work-in-progress research projects about efficient machine learning. Suggested topics for papers include, but are not limited to the ones listed on this page. The proceedings from previous instances have been published through the prestigious IEEE Conference Publishing Services (CPS) and are available to the community via IEEE Xplore. In each instance, IEEE conducted independent assessment of the papers for quality.

Safety and Security at the Heart of Autonomous Driving
Kamal Khouri, NXP Semiconductors
The automotive industry is undergoing a revolution with connected, autonomous and electric vehicles and the benefits they can bring to the public. Drivers enjoying their daily commute, fewer road fatalities and less pollution are all possible thanks to new technologies. Car makers need to offer these features but at the same time make sure vehicles are safe and secure. In the coming years, there will be various levels of automation until we have fully autonomous vehicles. To achieve any level of automation, cars need to connect to other vehicles, connect to the infrastructure, sense the environment through various sensors such as camera and radar and then make maneuvering decisions based on all these inputs. Artificial intelligence is and will be deployed heavily to accomplish many of the tasks of autonomous driving. Perception and decision-making based on artificial intelligence introduces an entirely new set of challenges to car makers to ensure no security compromises as well as proving the decisions being made are functionally, behaviorally and environmentally safe. The challenge can be described in a simple question: “If a machine learning based car system is accurate 99% of the time, are you willing to ride this car knowing that it will be wrong 1% of the time? What is the consequence of that incorrect decision?” Deep expertise and research in the safety and security aspects of AI are needed to ensure future mass deployment and success in the area of autonomous driving.

Challenges and Solutions for Embedding Vision AI
Charles Qi, Tensilica/Cadence
Recently computer vision and neural network based AI technology have seen explosive demands in embedded systems such as robots, drones, autonomous vehicles, etc. Due to cost and power constraints, it remains quite challenging to achieve satisfactory performance, while maintaining power efficiency and scalability for embedded vision AI. This presentation first analyzes the technical challenges of embedding vision AI, from the perspectives of algorithm complexity, computation and memory BW demands, and constrains of power consumption profile. The analysis shows that modern neural networks for vision AI contain complex topology and diversified computation steps. These neural networks are often part of a large embedded vision processing pipeline, intermixed with conventional vision algorithms. As a result, the vision AI implementation demands several TOPS computation performance and ten’s of GB memory BW. Subsequently the architecture of Tensilica Vision AI DSP processor technology is presented with three distinctive advantages: The optimized instruction sets of Vision P6 and Vision C5 DSP are explained as examples of achieving instruction level computation efficiency and performance. This is coupled with unique processor architecture features for achieving SoC level data processing efficiency and scalability that lead to a high-performance vision AI sub-system. The fully automated AI optimization framework, software libraries and tools provide practical performance tuning methodology and rapid turn-around time for embedded vision AI system design. In conclusion, the presentation offers considerations for future research and development to bring embedded vision AI to the next performance level.

Introducing ReQuEST: an Open Platform for Reproducible and Quality-Efficient Systems-ML Tournaments
Grigori Fursin, dividiti and cTuning Foundation link
Co-designing efficient machine learning based systems across the whole application/hardware/software stack to trade off speed, accuracy, energy and costs is becoming extremely complex and time consuming. Researchers often struggle to evaluate and compare different published works across rapidly evolving software frameworks, heterogeneous hardware platforms, compilers, libraries, algorithms, data sets, models, and environments. I will present our community effort to develop an open co-design tournament platform with an online public scoreboard based on Collective Knowledge workflow framework (CK). It gradually incorporates best research practices while providing a common way for multidisciplinary researchers to optimize and compare the quality vs. efficiency Pareto optimality of various workloads on diverse and complete hardware/software systems. All the winning solutions will be made available to the community as portable and customizable “plug&play” components with a common API to accelerate research and innovation!
I will then discuss how our open competition and collaboration can help to achieve energy efficiency for cognitive workloads based on energy-efficient submissions from the 1st ReQuEST tournament co-located with ASPLOS’18. Further details: http://cKnowledge.org/request
