com James Martens jmartenscstorontoedu George Dahl gdahlcstorontoedu Geo rey Hinton hintoncstorontoedu Abstract Deep and recurrent neural networks DNNs and RNNs respectively are powerful mod els that were considered to be almost impos sible to train. We will now quantify exactly how it hits the fan.. Momentum. Momentum = product of mass X velocity. Symbol for momentum is “p” (don’t ask me why). So, p = . mv. Momentum is also a vector and points in the direction of velocity. . EM/. Posterior Regularization . (. Ganchev. et al, 10). E-step:. M. -step: . argmax. w. . E. q. . log . P . (. x. , . y. ; . w. ).

Momentum is a quantity defined as the product of the mass and velocity of an object.. Unit of Momentum. The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity.. What is Momentum? Momentum may be defined by its equation: Momentum is a quantity defined as the product of the mass and velocity of an object. Unit of Momentum The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity. EMC/NCEP/NWS/NOAA. Young C. Kwon, V. Tallapragada, R. Tuleya, Q.

Measures how hard it is to stop a moving object.. Momentum can be defined as . "mass in motion.". . All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. .
