Biological neural networks process streams of temporal information at efficiencies and proficiencies well exceeding those of man-made systems. Recent work in understanding brain dynamics from the point of view of machine learning is starting to demystify the mechanisms behind their extraordinary performance. By distilling these mechanisms in neuromorphic technologies, the prospect of practical brain-like processing at the edge is becoming real. However, the tools at the disposal of neuroscientists and engineers to prototype and train such models are still inadequate. In this poster, I explain the potential rewards and challenges of training biological neural networks, namely Spiking Neural Networks (SNNs). I will provide the roadmap for the solutions to these problems, which build on an exciting combination of autodifferentiation techniques and dynamics inspired by neurobiology.

 Electronic design and design automation (EDA) is a key enabling technology in the advancement of information processing that we are enjoying today. EDA has provided fundamental design principles and tools empowering the exponential growth of the number of transistors on an integrated circuit chip over the past 50 years. Without EDA, it would not have been possible for billion-transistor chips to be a reality! 

After five decades of growth, the field of EDA now faces some unique challenges. On one hand, we are approaching the physical limit of transistor scaling, and the golden days of exponential growth in transistor density are over. The exorbitant cost of integrated circuit fabrication and the excessive complexity of EDA tools make it difficult to bring design automation innovations to practice. On the other hand, the recent rise of machine learning and artificial intelligence applications and emerging architectures and technologies calls for more customized solutions to designing electronic systems. 

## **Objectives of the Workshop:**

This workshop, funded by the National Science Foundation (NSF), will assemble a diverse group of leading researchers from both academia and industry to identify future research directions in design and design automation of electronic systems and architectures in response to the challenges and opportunities. It will feature plenary talks and panels as well as roundtable discussions. Collectively, the workshop attendees will explore answers to overarching questions such as 

•	what are the high-risk and high-return research topics, 

•	what other fields adjacent to EDA research should be aggressively pursued for highly interdisciplinary collaboration, and

•	where the research funding should come from and how it should be distributed to encourage more transformative research. 

The workshop will also include a satellite event with a roundtable panel discussion on strategies to improve foundry access to US-based EDA researchers. A final report, based on the deliberations of the workshop, will be produced to the government recommending future research directions.


Our CAREER research aims to developing novel computing systems exploiting Three-Independent-Gate Field Effect Transistors (TIGFETs), a novel device technology capable of device-level functionalities typically not achievable by standard CMOS and leading to major benefits at gate and circuit levels. A TIGFET is capable of dynamic reconfiguration of its polarity. In order to fully assess the potential of this technology, we are demonstrating: (1) the fabrication, characterization and modeling of TIGFETs using advanced semi-conductor materials, (2) the development of a complete design framework for TIGFETs, including a design kit, novel circuit primitives and dedicated design tools, and (3) the evaluation of TIGFET-enabled systems.

Functionality-enhanced Devices for Extending Moore's Law

Deep neural networks (DNNs) have gained widespread applications in numerous applications, especially for embedded and Internet-of-Things (IoT) devices. Nowadays on-device DNN inference has been extensively investigated because of its inherent advantages on data privacy, response time and bandwidth demand than cloud-based inference. On the other side, on-device DNN learning, which also has very strong practical demands and owns the similar advantages over the cloud-based training, however, has not been widely studied yet due to the dilemma between expensive training cost and limited on-device resource.  To address this challenge and promote the further deployment of on-device learning, this project proposes to leverage low-rank tensors, as a powerful mathematical tool for representing and compressing tensor-format data, to achieve real-time energy-efficient DNN learning on the device.

TensorNN: An Algorithm and Hardware Co-design Framework for On-device Deep Neural Network Learning using Low-rank Tensors

Machine learning is the key to sustaining the economic growth in many sectors within the U.S. science and engineering enterprise. Neuromorphic architectures that mimic biological neurons and synapses can execute machine learning algorithms in an energy-efficient manner, allowing for their integration with the internet-of-things, another industry sector projected to have an economic impact of more than $1 trillion by 2025. However, neuromorphic architectures are fundamentally unreliable. They introduce errors during execution, limiting the dependability of machine learning and impeding their technological progress. This project will address dependability challenges of neuromorphic computing, by looking at all levels, from building error-resilient machine learning algorithms to designing fault-tolerant hardware. This project will advance the field by 1) making neuromorphic computing reliable, efficient, programmable, and easy-to-use for the community, 2) teaching future science and engineering students how to make machine learning algorithms error-resilient, 3) creating job opportunities in neuromorphic industry through national and international internships and collaborations, 4) raising interest of high school students in STEM through neuromorphic computing enabled robotics workshops, and 5) building an integrated neuromorphic community through a new focused conference on neuromorphic computing.

Facilitating Dependable Neuromorphic Computing: Vision, Architecture, and Impact on Programmability

We present and investigate a novel application domain for deep reinforcement learning (RL): droplet routing on digital microfluidic biochips (DMFBs). A DMFB, composed of a two dimensional electrode array, manipulates discrete fluid droplets to automatically execute biochemical protocols such as point-of-care clinical diagnosis. However, a major concern associated with the use of DMFBs is that electrodes in a biochip can degrade over time. Droplet-transportation operations
associated with the degraded electrodes can fail, thereby compromising the integrity of the bioassay outcome. We show that casting droplet transportation as an RL problem enables the training of deep network policies to capture the underlying
health conditions of electrodes and provide reliable fluidic operations. We propose a new RL-based droplet-routing flow that can be used for various sizes of DMFBs, and demonstrate reliable execution of an epigenetic bioassay with the RL droplet router on a fabricated DMFB. To facilitate further research, we also present a simulation environment based on the OpenAI Gym Interface for RL-guided droplet-routing problems on DMFBs.

On-chip Multi-Task Learning Analog Artificial Intelligence For Low-Cost Image-Based Environmental Monitoring

I reviewed this NSF CAREER project on deep neural network acceleration using crossbar arrays with resistive random access memory (RRAM). The research accomplishments include several generations of the silicon prototypes including small-scale crossbar array for convolutional kernel (with integrated oscillation neuron), and two generations of compute-in-memory macro with peripheral analog-to-digital converters taped-out in Winbond 90nm RRAM and TSMC 40nm RRAM processes. Another research outcome is the NeuroSim benchmark framework which is an end-to-end simulator to evaluate the deep neural network training/inference accuracy under non-ideal synaptic device properties and to estimate the cycle-accurate and trace-enabled hardware performance including the chip area and energy/latency. I also surveyed future research directions: 1) 3D integration with hybrid technology nodes; 2) ferroelectric transistor as synaptic device; 3) security issues with compute-in-memory.

CAREER: Scaling-up Resistive Synaptic Arrays for Neuro-inspired Computing

Information technology has entered the age of heterogeneous computing.  Across a variety of application domains, computing systems rely on highly heterogeneous architectures that combine multiple general-purpose processors with specialized hardware accelerators.  The complexity of these systems, however, threatens to widen the gap between the capabilities provided by semiconductor technologies and the productivity of computer engineers. Embedded Scalable Platforms (ESP) is a new approach to the design and programming of heterogeneous computing systems that raises the level of abstraction in the design process. ESP is an open-source research platform for heterogeneous SoC design that combines a scalable tile-based architecture and a flexible system-level design methodology. Conceived as a heterogeneous integration platform and tested through years of teaching at Columbia University, ESP is naturally suited to foster collaborative engineering of SoC designs across the open-source community.
