Labeled negative lens diverging the light rays passing through the lens from an axis and convex lens converges the light rays passing through the lens to a point. The convex or biconvex lens is ...

Difference between Concave vs Convex Lens: Isn’t physics one of those subjects that almost every student is scared of? Well why not, given the complexity of problems and difficulty level of the ...

In a previous paper, we showed that gradient maps of exponentially concave functions provide solutions to a Monge–Kantorovich optimal transport problem and give a better gradient approximation than ...

In this paper, we propose a distributed stochastic first-order method for saddle point problems over strongly connected graphs. Existing methods generally suffe ...
