tinyML Summit 2020

Enabling ultra-low Power Machine Learning at the Edge

February 12-13, 2022

About the tinyML Summit

Following the success of the inaugural tinyML Summit 2019, the tinyML committee invites low power machine learning experts from the industry, academia, start-ups and government labs from all over the Globe to join the tinyML Summit 2020 to share the “latest & greatest” in the field and to collectively drive the whole ecosystem forward.

Tiny machine learning is broadly defined as a fast growing field of machine learning technologies and applications including hardware (dedicated integrated circuits), algorithms and software capable of performing on-device sensor (vision, audio, IMU, biomedical, etc.) data analytics at extremely low power, typically in the mW range and below, and hence enabling a variety of always-on use-cases and targeting battery operated devices. The inaugural tinyML Summit in March 2019 showed very strong interest from the community with active participation of senior experts from 90 companies. It revealed that: (i) tiny machine learning capable hardware is becoming “good enough” for many commercial applications and new architectures (e.g. in-memory compute) are on the horizon; (ii) significant progress on algorithms, networks and models down to 100kB and below; and (iii) initial low power applications in the vision and audio space. There is growing momentum demonstrated by technical progress and ecosystem development.

tinyML Summit 2020 will continue the tradition of high quality invited talks, poster and demo presentations, open and stimulating discussions, and significant networking opportunities. It will cover the whole stack of technologies (Systems-Hardware-Algorithms-Software-Applications) at the deep technical levels, a unique feature of the tinyML Summits. While the majority of the participants and speakers will come from industry, leading edge academic research will be represented as well as an important ingredient of the evolving tiny machine learning ecosystem. In 2020, special attention will be given to recent progress on algorithm development and tiny machine learning use-cases and applications. The program will be organized in four technical sessions: Hardware, Systems, Algorithms & Software, and Applications. There will be approximately twenty invited presentations selected by the Technical Program Committee and dedicated poster sessions and demos by tiny machine learning companies and sponsors. Overview and hands-on tutorials on hardware and software developments will be available the day before the main technical program starts. Registration will open in October 2019.

Hardware-Aware Neural Architecture Search and Compression for Efficient Deep Learning

Han CAI, PHD Student, MIT

Abstract (English)

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. Human engineers can hardly exhaust the design space by heuristics. 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, so that we can afford to design specialized neural network models for different hardware platforms. Finally, we accelerate computation-intensive AI applications including TSM for efficient video recognition and PVCNN for efficient 3D recognition on point clouds. Bio: Song Han is an assistant professor at MIT EECS. Dr. Han received the Ph.D. degree in Electrical Engineering from Stanford advised by Prof. Bill Dally. Dr. Han’s research focuses on efficient deep learning computing. He proposed “Deep Compression” and “ EIE Accelerator” that impacted the industry. His work received the best paper award in ICLR’16 and FPGA’17. He was the co-founder and chief scientist of DeePhi Tech which was acquired by Xilinx

Resource Efficient ML in a Few KBs of RAM

Prateek JAIN, Sr. Principal Researcher, Microsoft

Abstract (English)

Several critical applications require ML inference on resource-constrained devices, especially in the domain of Internet of Things like smartcity, smarthouse etc. Furthermore, many of these problems reduce to time-series classification. Unfortunately, existing techniques for time-series classification like recurrent neural networks are very difficult to deploy on the tiny devices due to computation and memory bottleneck. In this talk, we will discuss two new methods FastGRNN and SRNN that can enable time-series inference on devices as small as Arduino Uno that have 2KB of RAM. Our methods can provide as much as 70x speed-up and compression over state-of-the-art methods like LSTM, GRU, while also providing strong theoretical guarantees.

Next Generation Machine Learning for Mobile and Embedded Platforms

Sang WON LEE, Co-founder and CEO, Qeexo

Abstract (English)

Modern day machine learning systems typically involve development of large networks/models that require deployment of huge cloud servers for the compute capacity which have big privacy implications and result in high costs. Small micro-controller powered devices are being overlooked for ML applications as achieving high model accuracies within the memory and latency constraints is a challenge. With the right set of tools and algorithms, this need not be the case. The technology presented here discusses ways to leverage the use of these devices that occupy our world in the billions and make them intelligent with light-weight machine learning. A platform has been developed that enables development of models optimized for these low power devices. This talk will discuss some exemplary commercial uses of this technology and the processes and suite of tools that are used to deliver new interactive experiences to hundreds of millions of end users.

Some Micro Robots that Need ML

Kris PISTER, Professor, University of California, Berkeley

Abstract (English)

All of the components necessary for making swarms of autonomous micro robots, or silicon insects, now exist. Like their biological inspiration, they will be able to scavenge and store energy, lift many times their own weight, sense and interact with their environment, and collaborate to achieve goals beyond the abilities of an individual. Two characteristics distinguish them from their biological cousins: communication, and intelligence. Silicon insects will use RF mesh networks which will enable them to communicate over distances and at bit rates orders of magnitude higher than real insects, and indeed to reach back to cloud-based resources unavailable to their chitinous friends. But their native intelligence will pale in comparison to the lowliest ant or laziest bee. Here we have an opportunity for TinyML.

Voice Separation With tinyML on the Edge

Niels PONTOPPIDAN, Research Manager, Augmented Hearing Science at Eriksholm Research Center

Abstract (English)

With the recent advances in many areas of tiny ML several use cases where tiny ML is an absolute requirement has emerged. Hearing devices is an area where tiny ML holds the potential to radically transform the functionality of a 1 mW always on device. People with hearing problems can benefit from hearing device processing that separates competing voices into individual channels followed by resynthesizing of the auditory scene with spatial augmentation. The first successful segregation enhancement of competing voices required deep neural networks to achieve enough separation for the spatial augmentation to enhance segregation. It is furthermore a requirement that the latency of processing is below 20 ms – preferably less – and thus the processing must take place at the ear level without uplink and downlink latencies. Thus, for voice separation to work on the ears of people with hearing problems tiny ML is a necessity.

Thinking Big with Tiny ML: Low Power High Performance DNN Accelerators for Mobile and IoT Applications

Hoi-Jun YOO, Professor, KAIST

Abstract (English)

The artificial intelligence (AI) revolution is being widely spread even to the IoT with the help of 5G wireless communication. Compared to the Cloud-based or Edge-based AI applications, Internet-ofThings (IoT) applications require more autonomous, adaptive, and cooperative operations with extremely limited power, computing and memory resources without stable communication channels. AI, especially deep neural network (DNN), is the key technology to support such autonomy and adaptivity of the IoT machines in an unpredictable environment with limited available information. The IoT machines should contain not only inference but also training capabilities to adapt to environmental changes based on their experiences. Therefore, software and hardware co-optimization for DNN training is necessary for low-power and high-speed accelerators, in the same way it brought a dramatic increase in the performance of DNN inference accelerators. In addition, deep reinforcement learning (DRL) accelerators will be an essential part of the tide, showing a lot of benefits at making continuous decisions in an unknown environment, where labeled data is difficult to acquire.

Deep Model Compression and Acceleration Towards On-Sensor AI

Changkyu CHOI, Senior Vice President, Samsung Advanced Institute of Technology

Abstract (English)

ML Inference on embedded hardware has been attracting attention for many applications. Limitations on computing power, memory usage, and power consumption are major bottleneck to deploy deep neural networks on resource-constrained devices. Existing techniques to mitigate the limitations often involve power-latency tradeoff and yield degraded accuracy. This talk presents algorithm studies of deep model compression and computational acceleration on facial recognition tasks including face detection and anti-spoofing. A trainable quantizer is proposed to learn intervals to quantize activations and weights. This quantization-interval-learning allows the quantized networks to maintain the accuracy of the full precision (32-bit) networks with bit-width of activations and weights as low as 4-bit. The effectiveness of our trainable quantizer on ImageNet dataset will be demonstrated with various network architectures such as AlexNet, VGG-16, ResNet-50, Inception-V3, and so on. Furthermore, this talk proposes ‘On-sensor AI’ computing architecture while exploring the advantages of 4-bit (or less) operations of activations and weights. 4-bit MAC operation can be implemented by utilizing AND and COUNT operations only. The speed of computation of AND/COUNT implementation is similar to the one of Multiplier/Adder implementation. However, it becomes way faster if the bit-width goes down to 3-bit or less. Moreover, replacing the Multiplier & Adder with logical AND & COUNT operators can reduce the number of transistor counts by over 40 times. This ‘On-sensor AI’ is challenging but promising. This will pave the way to deploy highly accurate tiny ML models to things in everyday life.

Making optimizing and deploying Tiny Machine Learning on STM32 Microcontrollers easy

Matthieu DURERIN, AI Applications Manager, STMicroelectronics

Abstract (English)

Providing machine learning based algorithms that are able to run efficiently on Tiny devices like microcontrollers is already a challenge. Making it easy and affordable for data scientists and embedded software experts is a key step for market adoption of this technology. STMicroelectronics has developed tool STM32Cube.AI so that customers have an easy path to enable neural networks on any device across the broad STM32 microcontroller portfolio. The tool maps and runs pre-trained Neural Networks on STM32 microcontrollers and supports a wide range of popular deep-learning training tools like Keras, Tensor Flow Lite, Caffe… and ONNX format. It also takes advantage of quantization by supporting post-training quantization and quantized-aware learning models. The presentation will include the latest features of the STM32Cube.AI tool. To complement STM32Cube.AI, STMicroelectronics has developed software packages for quick and easy prototyping with end-to-end Audio, Motion and Vision examples. Audio and Motion use cases, such as human activity recognition and audio-scene classification, are running on STM32L4 ultra-low-power microcontrollers. Computer Vision examples, like food classification, are running on STM32H7 microcontrollers. Examples cover a wide range of options like quantized or float models and different memory configurations.

tinyMLPerf: Benchmarking Ultra-low Power Machine Learning Systems

Vijay JANAPA REDDI, Associate Professor, Harvard University

Abstract (English)

Tiny machine learning (ML) is poised to drive enormous growth within the IoT hardware and software industry. Measuring the performance of these rapidly proliferating systems, and comparing them in a meaningful way presents a considerable challenge; the complexity and dynamicity of the field obscure the measurement of progress and make embedded ML application and system design and deployment intractable. To foster more systematic development, while enabling innovation, a fair, replicable, and robust method of evaluating tinyML systems is required. A reliable and widely accepted tinyML benchmark is needed. To fulfill this need, tinyMLPerf is a community-driven effort to extend the scope of the existing MLPerf benchmark suite (mlperf.org) to include tinyML systems. With the broad support of over 75 member organizations, the tinyMLPerf group has begun the process of creating a benchmarking suite for tinyML systems. The talk presents the goals, objectives, and lessons learned (thus far), and welcomes others to join and contribute to tinyMLPerf.
