Abstract: This work proposes a new recurrent neural network (RNN) algorithm for solving discrete multilayer dynamic systems (DMDSs). First, by utilizing the direct-discretization technique, a ...

Abstract: This letter introduces a set-theoretic state estimation approach for bounded-error nonlinear discrete-time systems, subject to nonlinear observations or ...

Dark matter has long been the universe’s most profound ghost, its existence confirmed only by the gravitational havoc it wreaks on visible galaxies. Now, a team from the University of Tokyo suggests ...

Computers are extremely good with numbers, but they haven’t gotten many human mathematicians fired. Until recently, they could barely hold their own in high school-level math competitions. But now ...
