The concentration of the world’s population around cities has resulted from the impact of the three industrial revolutions we have experienced in the past 250 years. The First Industrial Revolution originated in England in the late eighteenth century and used water and steam power to mechanize production. It resulted in the early rise of the city as a center of activity, when farming became more effective using mechanization and more people turned to cities for work. The Second Industrial Revolution in the late nineteenth century started in the US and used electric power to create mass production, which brought even more people from rural areas and farms to the assembly lines. The Third Industrial Revolution also originated in the US in the mid to late twentieth century, and used electronics and information technology to automate production, thus forcing people out of the assembly lines and in unemployment.
Now in less than fifty years from the beginning of the previous technological revolution we stand on the brink of a new one which may be more powerful and more dangerous than all the previous ones. In its scale, scope, and complexity, this transformation may be unlike anything we have experienced before.
"The Fourth Industrial Revolution is building on everything we have discovered so far and it is using the internet to connect humans and machines in one task".
It may bring together technology and culture in a clash of unprecedented proportions resulting in further concentration of population to what we call Mega-Cities and more social instability. Farm land will be managed by robots, factories will employ robots, and humans will use robots for low level jobs leaving us wonder of what role humans will eventually play in this futuristic society.
This seminar series will bring speakers who will present various aspects of the Third Industrial Revolution (Age of Computers) with specific focus on electronic applications and could speculate on the challenges and opportunities of the next one. Considering that the world we live in is a construct of many designed systems, engineering could play a key role in addressing many of the possible negatives this new revolution may bring about and create a more just world.

Neuromorphic Computation for Cognitive Computing: Challenges and Perspectives
IBM Research Almaden
Cognitive computing describes “systems that learn at scale, reason with purpose, and interact with humans naturally”. To achieve this goal, researchers are considering a move away from Von-Neumann computing towards one or more novel and significantly different computing architectures. Among these, neuromorphic computation stands as an innovative solution for solving high-complexity problems by emulating the behavior of the human brain. This can offer several attractive features, such as the resilience of algorithms to device variability and non-ideality.
In this presentation, we review our recent work towards designing a neuromorphic chip for hardware acceleration of training and inference of Fully Connected and Convolutional Deep Neural Networks (DNNs). The training is performed through the backpropagation algorithm, with performance – in terms of speed and power – that could potentially outperform current CPUs and GPUs. We use arrays of emerging non-volatile memories (NVM), such as Phase Change Memory, to implement the synaptic weights connecting layers of neurons. The corresponding network has been demonstrated through experimental results on real devices. We address the impact of real device characteristics – such as non-linearity, variability, asymmetry, and stochasticity – and present some solutions to tackle these sorts of issues. After this, we will discuss some of the challenges in designing the CMOS circuitry around the NVM array. To achieve high processing speed, there is a need for highly parallel circuitry, which introduces a tradeoff between neuron complexity and area. The limited silicon space available makes it essential for designers to implement compact neurons with approximate functionality that can still support accurate DNN training. Then, the talk deals with some architectural guidelines, showing the issues and challenges associated with routing information between different arrays to implement multi-layer DNNs. Finally, other neuromorphic approaches are shown, as, e.g., networks trained with the Spike-Timing-Dependent-Plasticity biological protocol, underlining the differences with the backpropagation algorithm and the need for extensive global studies in this field.
Dr. Linda Katehi pioneered the development and implementation of Unified Theory and Design Algorithms for the simultaneous design of high frequency 3-D Integrated Circuits and Antennas. In this development she pioneered the methodology to treat 3-D circuits as radiating elements at discontinuities and interconnects thereby allowing the accurate modeling of cross talk and substrate material effects. To achieve this goal she “cracked” for the first time the solution of Integral Equations with improper integrands. Her contributions with this part of her work have had and are having a fundamental impact in communication technologies such as in 3-D integrated circuit and antenna design, especially for wireless communications.
Professor Katehi is an expert in the areas of development and characterization (theoretical and experimental) of microwave, millimeter printed circuits; the computer-aided design of VLSI interconnects; the development and characterization of micro-machined circuits for microwave, millimeter-wave and sub-millimeter-wave applications including MEMS switches, high-Q evanescent mode filters and MEMS devices for circuit re-configurability; the development of low-loss lines for sub-millimeter-wave and terahertz frequency applications; theoretical and experimental study of uniplanar circuits for hybrid-monolithic and monolithic oscillator, amplifier and mixer applications; theoretical and experimental characterization of photonic band-gap materials.
Katehi has been a pioneer in studying high-frequency effects on planar circuits and understanding parasitic radiation, substrate-wave propagation, and the importance of high-frequency parasitic phenomena on the performance of planar circuits. Her work demonstrated that 3-D integration is the approach to achieve high performance in high frequencies. In pursue of fully integrated three-dimensional circuit architectures and on-wafer packaging, she explored for the first time the use of Si-micro-machining in circuit design.
Katehi developed three dimensional circuit integration architectures and on wafer packaging that have been adopted by industry as the architecture for the next generation of high-frequency circuits. Based on Katehi’s work DARPA funded four major research and development programs, MAFET III, IRFFE, MERFS and SMART, of a total of $200M to demonstrate 3-D circuit architectures on receive and transmit systems operating between 2Ghz and 94GHz.
Furthermore, the defense industry is now using the architectures pioneered by Prof. Katehi to develop the RF front ends of the next generation of military sensors such as XG, JTRS, GPS-Guided Munitions. Specifically, Lincoln Labs and Northrop Grumman have adopted the on-wafer packaging for RF MEMS which was demonstrate by Katehi’s work and Raytheon and Rockwell Collins used these three-dimensional interconnects for their reconfigurable high-frequency RF systems.
Prof. Katehi’s fundamental designs have been incorporated in the development of new systems worth a total of $1B-$10B in the defense economy and due to substantial gains in size and performance have provided savings of many hundreds of million of dollars in the cost of these systems.
This blog explores early signs of a new revolution, the Fourth Industrial Revolution. It examines the internet, the cloud, robotics and multiculturalism as drivers of change.
The changes that are foreseen coming are so fundamental that there is only one hypothesis to embrace. There is a new industrial revolution that is coming so strong, so encompassing and unforgiving that we should prepare to drive it but not be driven by it.
