Similar to a mouse racing through a maze, making "yes" or "no" decisions at every intersection, researchers have developed a way for machines to swiftly learn all the twists and turns in a complex data system.
"Our method may help improve the diagnosis of urinary diseases, the imaging of cardiac conditions and analysis of financial risks," reported Abd-AlRahman Rasheed AlMomani of Embry-Riddle Aeronautical University's Prescott, Arizona, campus.
The research was accepted for the Nov. 11 edition of the journal Patterns with Jie Sun and Erik Bollt of Clarkson University's Center for Complex Systems Science. The goal of the work is to more efficiently analyze binary ("Boolean") data.
"We can see everything around us as a network of objects and variables that interact with each other," said AlMomani, assistant professor of Data Science and Mathematics at Embry-Riddle. "Understanding those interactions can improve our predictions and management of a whole host of networks—from biology and gene regulatory networks, to even air flight."
Boolean, or "yes/no," data are frequently used in the field of genetics, where gene states may be described as "on" (with high gene expression), or "off" (with little or no gene expression), AlMomani explained. Learning Boolean functions and networks based on noisy observational data is key to deciphering many different science and engineering problems—from plant-pollinator dynamics and drug targeting, to assessing a person's risk of tuberculosis.
The challenge, AlMomani explained, is that the standard method for learning Boolean networks—called REVEAL (for reverse engineering algorithm for interference of genetic network architectures)—blends many different sources of information. The REVEAL approach thus increases computational complexity and costs, and researchers must dampen noise to analyze all of the data. Further, the REVEAL method isn't optimal for solving quantitative biology problems, which require uncovering causal factors.
