The 5th Workshop on Energy Efficient Machine Learning and Cognitive Computing
Co-located with the 33rd Conference on Neural Information Processing Systems NeurIPS 2019
description Workshop Objective
As artificial intelligence and other forms of cognitive computing continue to proliferate into new domains, many forums for dialogue and knowledge sharing have emerged. In the proposed workshop, the primary focus is on the exploration of energy efficient techniques and architectures for cognitive computing and machine learning, particularly for applications and systems running at the edge. For such resource constrained environments, performance alone is never sufficient, requiring system designers to carefully balance performance with power, energy, and area (overall PPA metric).
The goal of this workshop is to provide a forum for researchers who are exploring novel ideas in the field of energy efficient machine learning and artificial intelligence for a variety of applications. We also hope to provide a solid platform for forging relationships and exchange of ideas between the industry and the academic world through discussions and active collaborations.

A new wave of intelligent computing, driven by recent advances in machine learning and cognitive algorithms coupled with process technology and new design methodologies, has the potential to usher unprecedented disruption in the way conventional computing solutions are designed and deployed. These new and innovative approaches often provide an attractive and efficient alternative not only in terms of performance but also power, energy, and area. This disruption is easily visible across the whole spectrum of computing systems -- ranging from low end mobile devices to large scale data centers and servers.
A key class of these intelligent solutions is providing real-time, on-device cognition at the edge to enable many novel applications including vision and image processing, language translation, autonomous driving, malware detection, and gesture recognition. Naturally, these applications have diverse requirements for performance,energy, reliability, accuracy, and security that demand a holistic approach to designing the hardware, software, and intelligence algorithms to achieve the best power, performance, and area (PPA).

Efficient Computing for AI and Robotics
Computing near the sensor is preferred over the cloud due to privacy and/or latency concerns for a wide range of applications including robotics/drones, self-driving cars, smart Internet of Things, and portable/wearable electronics. However, at the sensor there are often stringent constraints on energy consumption and cost in addition to the throughput and accuracy requirements of the application. In this talk, we will describe how joint algorithm and hardware design can be used to reduce energy consumption while delivering real-time and robust performance for applications including deep learning, computer vision, autonomous navigation/exploration and video/image processing. We will show how energy-efficient techniques that exploit correlation and sparsity to reduce compute, data movement and storage costs can be applied to various tasks including image classification, depth estimation, super-resolution, localization and mapping.

Putting the “Machine” Back in Machine Learning: The Case for Hardware-ML Model Co-design
Machine learning (ML) applications have entered and impacted our lives unlike any other technology advance from the recent past. Indeed, almost every aspect of how we live or interact with others relies on or uses ML for applications ranging from image classification and object detection, to processing multi‐modal and heterogeneous datasets. While the holy grail for judging the quality of a ML model has largely been serving accuracy, and only recently its resource usage, neither of these metrics translate directly to energy efficiency, runtime, or mobile device battery lifetime. This talk will uncover the need for building accurate, platform‐specific power and latency models for convolutional neural networks (CNNs) and efficient hardware-aware CNN design methodologies, thus allowing machine learners and hardware designers to identify not just the best accuracy NN configuration, but also those that satisfy given hardware constraints. Our proposed modeling framework is applicable to both high‐end and mobile platforms and achieves 88.24% accuracy for latency, 88.34% for power, and 97.21% for energy prediction. Using similar predictive models, we demonstrate a novel differentiable neural architecture search (NAS) framework, dubbed Single-Path NAS, that uses one single-path over-parameterized CNN to encode all architectural decisions based on shared convolutional kernel parameters. Single-Path NAS achieves state-of-the-art top-1 ImageNet accuracy (75.62%), outperforming existing mobile NAS methods for similar latency constraints (∼80ms) and finds the final configuration up to 5,000× faster compared to prior work. Combined with our quantized CNNs (Flexible Lightweight CNNs or FLightNNs) that customize precision level in a layer-wise fashion and achieve almost iso-accuracy at 5-10x energy reduction, such a modeling, analysis, and optimization framework is poised to lead to true co-design of hardware and ML model, orders of magnitude faster than state of the art, while satisfying both accuracy and latency or energy constraints.

Abandoning the Dark Arts: New Directions in Efficient DNN Design
Deep Neural Net models have provided the most accurate solutions to a very wide variety of problems in vision, language, and speech; however, the design, training, and optimization of efficient DNNs typically requires resorting to the “dark arts” of ad hoc methods and extensive hyperparameter tuning. In this talk we present our progress on abandoning these dark arts by using Differential Neural Architecture Search to guide the design of efficient DNNs and by using Hessian-based methods to guide the processes of training and quantizing those DNNs.

Hardware-aware Neural Architecture Design for Small and Fast Models: from 2D to 3D
Efficient deep learning computing requires algorithm and hardware co-design to enable specialization. However, the extra degree of freedom creates a much larger design space. We propose AutoML techniques to architect efficient neural networks. We investigate automatically designing small and fast models (ProxylessNAS), auto channel pruning (AMC), and auto mixed-precision quantization (HAQ). We demonstrate such learning-based, automated design achieves superior performance and efficiency than rule-based human design. Moreover, we shorten the design cycle by 200× than previous work to efficiently search efficient models, so that we can afford to design specialized neural network models for different hardware platforms. We accelerate computation-intensive AI applications including (TSM) for efficient video recognition and PVCNN for efficient 3D recognition on point clouds. Finally, we’ll describe scalable distributed training and the potential security issues of efficient deep learning

Advances and Prospects for In-memory Computing
Edge AI applications retain the need for high-performing inference models, while driving platforms beyond their limits of energy efficiency and throughput. Digital hardware acceleration, enabling 10-100x gains over general-purpose architectures, is already widely deployed, but is ultimately restricted by data-movement and memory accessing that dominates deep-learning computations. In-memory computing, based on both SRAM and emerging memory, offers fundamentally new tradeoffs for overcoming these barriers, with the potential for 10x higher energy efficiency and area-normalized throughput demonstrated in recent designs. But, those tradeoffs instate new challenges, especially affecting scaling to the level of computations required, integration in practical heterogeneous architectures, and mapping of diverse software. This talk examines those tradeoffs to characterize the challenges. It then explores recent research that provides promising paths forward, making in-memory computing more of a practical reality than ever before.

Algorithm-Accelerator Co-Design for Neural Network Specialization
In recent years, machine learning (ML) with deep neural networks (DNNs) has been widely deployed in diverse application domains. However, the growing complexity of DNN models, the slowdown of technology scaling, and the proliferation of edge devices are driving a demand for higher DNN performance and energy efficiency. ML applications have shifted from general-purpose processors to dedicated hardware accelerators in both academic and commercial settings. In line with this trend, there has been an active body of research on both algorithms and hardware architectures for neural network specialization.
This talk presents our recent investigation into DNN optimization and low-precision quantization, using a co-design approach featuring contributions to both algorithms and hardware accelerators. First, we review static network pruning techniques and show a fundamental link between group convolutions and circulant matrices – two previously disparate lines of research in DNN compression. Then we discuss channel gating, a dynamic, fine-grained, and trainable technique for DNN acceleration. Unlike static approaches, channel gating exploits input-dependent dynamic sparsity at run time. This results in a significant reduction in compute cost with a minimal impact on accuracy. Finally, we present outlier channel splitting, a technique to improve DNN weight quantization by removing outliers from the weight distribution without retraining.

Adaptive Multi-Task Neural Networks for Efficient Inference
Very deep convolutional neural networks have shown remarkable success in many computer vision tasks, yet their computational expense limits their impact in domains where fast inference is essential. While there has been significant progress on model compression and acceleration, most methods rely on a one-size-fits-all network, where the same set of features is extracted for all images or tasks, no matter their complexity. In this talk, I will first describe an approach called BlockDrop, which learns to dynamically choose which layers of a deep network to execute during inference, depending on the image complexity, so as to best reduce total computation without degrading prediction accuracy. Then, I will show how this approach can be extended to design compact multi-task networks, where a different set of layers is executed depending on the task complexity, and the level of feature sharing across tasks is automatically determined to maximize both the accuracy and efficiency of the model. Finally, I will conclude the talk presenting an efficient multi-scale neural network model, which achieves state-of-the art results in terms of accuracy and FLOPS reduction on standard benchmarks such as the ImageNet dataset.

Kernel and Graph Optimization for DL Model Execution
There is increasing demand to deploy diverse deep learning models on edge devices. However, fully optimizing the execution of such models on resource-constrained HWs (e.g., CPU, DSP, NPU) is intrinsically challenging and often requires significant manual efforts. In this talk, we introduce our Morpheus team’s efforts to address these challenges. First, we optimize the performance of DL model execution in kernel level (e.g., a convolution operator). From a large number of possible kernel configurations (e.g., tiling, unrolling, vectorizations), the fastest kernel is quickly identified through machine learning algorithms we developed while binary codes are automatically generated by TVM or Halide compilers. Second, we further optimize the performance of DL model execution in graph-level (e.g., end-to-end network). Since each kernel or operator is often connected as a graph in deep learning models, the compute scheduling of such graphs significantly affects the end-to-end performance, especially memory I/O. We solve two problems in this context. First, for potentially complex topologies on edge devices with limited total memory, we solve the minimum memory usage problem, thus characterizing and enabling deployment of all feasible networks on a given device. Second, for any hardware with combined Tightly Coupled Memory (TCM) and more expensive external memory (e.g. DRAM), we solve the minimum external memory access problem, which optimizes hardware usage efficiency in I/O-bound conditions. For both problems we show efficient algorithms that are complete solutions, and improved results over heuristic methods. Finally, we will discuss our future directions to optimize deep learning model execution.

description EMC2 Model Compression Challenge (EMCC)
Deep learning has recently pushed the state of the art boundaries in many computer vision tasks. However, existing deep learning models are both computationally and memory intensive, making their deployment difficult on devices with low compute and memory resources. To fit these emerging models on such devices, novel compression techniques are needed without significantly decreasing the model accuracy.
The EMC2 Model Compression Challenge (EMCC) aims to identify the best technology in deep learning model compression. To win a prize in EMCC, the solution will be evaluated to meet the two metrics in two tracks below:
- Achieve highest accuracy within the target model size. The submission will not be evaluated if the model size is outside of the target range.
