Computers Take a Lick at Diagnosis

Stick out your tongue and say "Ahhh." A group of engineers at the Harbin Institute of Technology in China and Hong Kong Polytechnic University recently trained a computer to perform tongue diagnosis, a traditional Chinese medicine technique for characterizing illness. Using Bayesian networks, a form of machine-automated statistical inference, the group trained a computer to correlate tongue features, such as color and texture, with illnesses, such as diabetes and heart disease. Experiments with patients showed a diagnostic accuracy of approximately 75 percent for some conditions, including hypertension and pancreatitis.

Asad Madni and the Life-Saving Sensor

In 1992, Asad M. Madni sat at the helm of BEI Sensors and Controls, overseeing a product line that included a variety of sensor and inertial-navigation devices, but its customers were less varied—mainly, the aerospace and defense electronics industries.

And he had a problem.

The Cold War had ended, crashing the U.S. defense industry. And business wasn’t going to come back anytime soon. BEI needed to identify and capture new customers—and quickly.
