Title of The Talk: Sparsity and Low Rank for Inference of Cognitive Communication Network States
Abstract.: Viewed through a statistical inference lens, many challenges facing communication network analytics boil down to (non-) parametric regression and classification, dimensionality reduction, or clustering. Adopting such a vantage point, this keynote presentation will put forth novel learning approaches for comprehensive situation awareness of cognitive radio (CR) communication networks that include spatio-temporal sensing via RF spectrum and channel gain cartography, flagging of network anomalies, prediction of network processes, and dynamic topology inference. Key emphasis will be placed on parsimonious models leveraging sparsity, low-rank or low-dimensional manifolds, attributes that are instrumental for complexity reduction.

Title of the Talk: Control algorithms for smooth prosthetic gait
Abstract: An estimated 23.6 million Americans are affected by Type II diabetes and 37,000 undergo lower limb amputation each year [CDC]. About half of these patients are prescribed a foot-ankle prosthesis, yet mobility is often severely restricted by pain and impaired walking dynamics — in turn, leading to cardiovascular disease and other comorbidities. In order to affect better health outcomes for persons with amputation, we have addressed the link between residual limb pathology and mechanical dysfunction of the prosthesis with what we call a Dynamic Intelligence System. This system allows the dynamics of a human wearer of prosthetics to enter the control loop of that prosthetic limb for the first time. This Dynamic Intelligence System mitigates the extreme environment at the prosthesis-residual limb interface by reducing the harsh impacts and oscillatory loads that cause compressive, shear, and bending stresses at the residual limb.

Title of the Talk: Interpretable Convolutional Neural Networks via Feedforward Design
Abstract:The superior performance of Convolutional Neural Networks (CNNs) has been demonstrated in
many applications such as image classification, detection and processing. Yet, CNN’s working principle remains a mystery. We offer an interpretable design for simple CNNs through a feedforward construction without backpropagation. A CNN is simple if it is a cascade of two networks; namely, the Conv net and the FC net. The Conv net consists of convolutional layers while the FC net contains fully connected layers. To design the Conv net, we develop a new signal transform, called the Saab (Subspace approximation with adjusted bias transform. The bias term in filter weights is chosen to annihilate nonlinearity of the activation function, which simplifies our design significantly. For the FC net design, we propose a label-guided linear least squared regression (L3SR) method. To shed light on the behavior of the FC net, we measure the cross-entropy at nodes of FC layers. The properties and performance of the traditional backpropagation design and the proposed feedforward design are compared and analyzed.

Title of the Talk: Memory Module Design, Architectures, and CommunicatioTwo Way Traffic Ahead: The Challenges and Future of Full Duplex Communications
Abstract: Integration of discrete radios onto a single-silicon CMOS substrate, followed by commercialization of single-chip cellular, Bluetooth, and Wi-Fi radios, has shaped the wireless world we live in today. Although integration of very large systems-on-chip (SoCs) which include wireless transceivers and powerful microprocessors, are commonplace in todays’ consumer electronics, the demand for lower power consumption, higher effective data rates, and higher network capacity continues to drive
research on integrated radios. By some estimates, the demand for mobile data per volume area will increase 1,000× during the next decade, with end-user data rates increasing by as much as 10–100×. A possible approach to close the gap between existing data rates and future demand could be the use of in-band full duplex communication which allows simultaneous communication using the same carrier frequency. However, realizing commercial single-chip radio solutions for full duplex communications presents numerous challenges. This presentation surveys the challenges and the current state-of-the-art in the areas of full duplex (FD) and frequency division duplex (FDD) integrated transceivers. Implementation hurdles in the form of the linearity, noise, bandwidth (BW) and power consumption of transmitter (TX) self- interference (SI) cancellation circuitry are explored. The difficulty of performing SI cancellation is heavily influenced by the modulation method, the maximum TX power output and the receiver (RX) channel BW. These issues are discussed using several recent publications as implementation examples of single-chip FD radios that range in performance from low-power cancellation techniques, to transceivers which target broad channel bandwidths using high-output-power Power Amplifiers, thus requiring deep SI cancellation.

Title of the Talk: Memory Module Design, Architectures, and Communications
Abstract:This talk presents an overview of the main memory system and proposed future directions.
This includes a historic review of memory modules, current topologies and performance, and future directions including a proposed direction for future memory module design. Since sustaining performance gains has power consumption, capacity, and cost moving in the wrong direction with the current memory modules, a novel module and interconnect architectures is proposed. The proposed architectures utilize inexpensive innovations, including interconnect and packaging, to substantially reduce the power, and increase the capacity and bandwidth of the main memory system. A low cost advanced packaging technology is used to propose an 8
die and 32-die memory module. The 32-die memory module measures less than 2 cm3. The size and packaging technique allow the memory module to consume less power than conventional module designs. A 4 Gb DRAM architecture utilizing 64 data pins is proposed.
The DRAM architecture is inline with ITRS roadmaps and can consume 50% less power while increasing bandwidth by 100%. The large number of data pins are supported by a low power capacitive-coupled interconnect. The receivers developed for the capacitive interface were fabricated in 0.5 µm and 65 nm CMOS technologies as a proof of concept. The 0.5 µm design operated at 200 Mbps, used a coupling capacitor of 100 fF, and consumed less than 3 pJ/bit of energy. The 65 nm design operated at 4 Gbps, used a coupling capacitor of 15 fF, and consumed less than 15 fJ/bit.

Title of the Talk: The impact of complexity and emergent properties on engineering
Abstract: Emergent properties in complex systems was first recognized in biological systems. In recent years various engineering disciplines, particularly systems engineering, have noted that emergent properties in complex systems can lead to unforeseen failures. However, there has been inadequate study of emergence in engineered system. This presentation will provide the essentials of emergence, specific impacts emergent properties have had on engineered systems, and suggestions for research to better understand and perhaps predict emergent properties in any engineered systems. The research spans multiple studies with the goal of providing some level of predictability to emergent properties in complex systems.
