The main problem of distributed learning is credit assignment, which was solved in the 80s with the invention of error backpropagation. 30 years later, Backprop, along with a few more recent tricks, is the major workhorse underlying machine learning and remains state-of-the-art for supervised learning. However, weight updates under Backprop depend on recursive computations that require distinct output and error signals -- features not shared by biological neurons, that are perhaps unnecessary.
David Balduzzi is a Senior Lecturer in Mathematics and Statistics at Victoria University Wellington.

Computational imaging uses new optics to capture a coded image, and an appropriate algorithm to decode the captured image. This approach of manipulating images before there are recorded and processing recorded images before they are presented has three key benefits. First, it enables us to implement imaging functionalities that would be difficult, if not impossible, to achieve using traditional imaging. Second, it can be used to significantly reduce the hardware complexity of an imaging system.
Shree K. Nayar is the T. C. Chang Professor of Computer Science at
Columbia University. He heads the Columbia Vision Laboratory (CAVE),
which develops advanced computer vision systems. His research is focused
on three areas - the creation of novel cameras that provide new forms
of visual information, the design of physics based models for vision and
graphics, and the development of algorithms for understanding scenes
from images. His work is motivated by applications in the fields of
digital imaging, computer graphics, robotics and human-computer
Nayar received his PhD degree in Electrical and Computer Engineering from the Robotics Institute at Carnegie Mellon University.

Presenter: Sanja Fidler (Homepage)
Friday March 20, 2015 from 11:00am to 12:00pm
A successful autonomous system needs to not only understand the visual
world but also communicate its understanding with humans. To make this
possible, language can serve as a natural link between high level
semantic concepts and low level visual perception. In this talk, I'll
present our recent work on 3D scene understanding, and show how natural
sentential descriptions can be exploited to improve 3D visual parsing,
and vice-versa, how image information can help resolve ambiguities in

Presenter: Noah Cowan (Homepage)
Friday April 17, 2015 from 11:00am to 12:00pm
Control systems engineering commonly relies on the
"separation principle", which allows designers to independently design
state observers and controllers. Biological control systems, however,
routinely violate the requirements for
separability. Indeed, animals often rely on a strategy known as "active
sensing" in which organisms use their own movements to alter
spatiotemporal patterns of sensory information to improve
task-level control performance.
Noah Cowan earned his Ph.D. from the University of Michigan, Ann Arbor, in 2001 in Electrical Engineering. Following his Ph.D., he was a Postdoctoral Fellow in Integrative Biology at the University of California, Berkeley for 2 years. In 2003, he joined Johns Hopkins University, where he is now an associate professor of Mechanical Engineering and directs the LIMBS Laboratory. Noah's research is devoted to understanding navigation and control in machines and animals.

Presenter: Ayanna Howard (Homepage)
Friday February 20, 2015 from 11:00am to 12:00pm
Robots for therapy applications can increase the quality of life for
children who experience disabling circumstances, by, for example,
becoming therapeutic playmates for children with neurological disorders.
There are numerous challenges though that must be addressed -
determining the roles and responsibilities of both clinician, child, and
robot; developing interfaces for clinicians to interact with robots
that does not require extensive training; and developing methods to
allow the robot to learn from their child counterpart.

Presenter: Dana Ballard (Homepage)
Friday February 6, 2015 from 11:00am to 12:00pm
The human motor control system is an extraordinarily
complex system that consists of layers of neural control
systems that address different demands of motive behavior. A
primary distinction between these systems can be made on the
basis of time. Systems in the forebrain operate on the order
Dr. Dana Ballard is currently a Professor in Computer Science at the University of Texas at Austin. He received his PhD in 1974 from the University of California, Irvine. Dr. Ballard's main research interest is in computational theories of the brain with emphasis on human vision. In 1985 Chris Brown and Dr. Ballard led a team that designed and built a high speed binocular camera control system capable of simulating human eye movements. The system was mounted on a robotic arm that allowed it to move at one meter per second in a two meter radius workspace. This system has led to an increased understanding of the role of behavior in vision. The theoretical aspects of that system were summarized in a paper ``Animate Vision,'' which received the Best Paper Award at the 1989 International Joint Conference on Artificial Intelligence. Currently, Dr. Ballard is interested in pursuing this research by using model humans in virtual reality environments. In addtion, he is interested in models of the brain that relate to detailed neural codes. A position paper on this work appeared in the Behavioral and Brain Sciences.
Presenter: Hanumant Singh (Homepage)
Friday January 30, 2015 from 11:00am to 12:00pm
The Arctic and Antarctic remain one of least explored parts of the
world's oceans. In this talk we look at efforts over the last decade to explore areas under-ice
which have traditionally been difficult to access. The focus of the talk will be on the robots,
the role of communications over low bandwidth acoustic links, and navigation and mapping
methodologies. This is all within the context of real data collected on several expeditions to the
Arctic and Antarctic.
Hanumant Singh graduated from the MIT WHOI Joint Program in 1995 after which he joined the staff at the Woods Hole Oceanographic Institution. His interests lie at the intersection of imaging and robotics underwater. Over the course of his career he has participated in more than 50 research expeditions all over the world in support of Marine Archaeology, Marine Geology and Geophysics, Marine Chemistry, Coral Reef Ecology, Fisheries and Polar Studies.
