The cover story in the Jan­u­ary issue of Wired is devoted to research at the fore­front of arti­fi­cial intel­li­gence. “Today’s AI doesn’t try to re-create the brain,” Wired writes. “Instead, it uses machine learn­ing, mas­sive data sets, sophis­ti­cated sen­sors, and clever algo­rithms to mas­ter dis­crete tasks.”

The piece fea­tures trans­porta­tion algo­rithms devel­oped by Prince­ton researchers to ana­lyze Nor­folk Southern’s rail oper­a­tions. The Prince­ton Loco­mo­tive and Shop Man­age­ment Sys­tem (Plasma for short) “tracks thou­sands of vari­ables, pre­dict­ing the impact of changes in fleet size, main­te­nance poli­cies, tran­sit time, and other fac­tors on real-world operations.”

Wired says that the key break­through was mak­ing the model “mimic the com­plex behav­ior of the company’s dis­patch cen­ter in Atlanta.”

Princeton’s War­ren Pow­ell ’77, a pro­fes­sor of oper­a­tions research and finan­cial engi­neer­ing at Prince­ton, tells Wired: “Think of the dis­patch cen­ter as one big, col­lec­tive brain. How do you get a com­puter to behave like that?”
