Decision-making models for reproducing intelligence in transportation


It could be the start of a good riddle: How many syn­apses of the brain does it take to figure out how to improve fuel efficiency? If you’re Andreas Malikopoulos, Energy and Transportation Science Division researcher and Alvin M. Weinberg Fellow, the answer is far from simple.

In late 2010, Malikopoulos joined ETSD with an interest in developing the information and decision science (IDS) thrust area and a desire to uncover how the brain works through reverse engineering. According to Malikopoulos, re­verse engineering the brain can reveal its secret code and functions – keys to developing decision-making models that enable the creation of thinking machines capable of emulating human intelligence. The intention is to weave ideas from statistical signal processing, stochastic control, and information theory into new ones drawn from neu­roscience, statistical learning theory, and game theory in order to create models that can represent four key func­tions of the brain--perception, attention, learning, and intelligence.

“Outcomes from understanding more about the brain could greatly impact and yield great increases in fuel and energy efficiency. We could also apply this knowledge in a number of other areas such as manufacturing, safety, healthcare and even finance,” Malikopoulos said.

His research to date has largely focused on issues relat­ed to vehicle fuel efficiency. Malikopoulos can implement com­putational intelligence models—based on data gleaned from reverse engineering of certain brain functionality— that can predict future behavior based on the user’s driving habits and patterns and adjust accordingly.

“This allows the vehicle to learn the driver, just like the brain allows us to learn based on past experience. As the vehicle gets smarter, its performance becomes more efficient to, for example, optimize miles per gallon,” he explained.

A more recent IDS research effort is a project called iVEHICLE (intelligent VEhicle and HIghway Communica­tion Leverage for Efficiency) that involves an optimization framework and control algorithms that will allow vehicles to “talk” to each other and with advanced information systems, sharing information so conventional vehicles will learn how to optimize fuel efficiency and plug-in HEVs will learn how to optimize their overall range.

Prior to joining ORNL, Andreas worked for General Mo­tors Global Research & Development conducting research in the area of stochastic control and hybrid systems with an emphasis on applications to advanced propulsion systems. As he seeks new findings at the intersection of neurosci­ence and engineering, he is connecting with DOE and in­dustry representatives who are looking into opportunities to further explore the potential benefits of this research.
