gradient ascent造句

In predictive coding, optimising model parameters through a gradient ascent on the time integral of free energy ( free action ) reduces to associative or Hebbian plasticity and is associated with synaptic plasticity in the brain.
NES then performs a gradient ascent step along the "'natural gradient "', a second order method which, unlike the plain gradient, renormalizes the update w . r . t . uncertainty.
If instead one takes steps proportional to the " positive " of the gradient, one approaches a local maximum of that function; the procedure is then known as "'gradient ascent " '.
The original method of half-way models was not optimal : the regular homotopies passed through the midway models, but the path from the round sphere to the midway model was constructed by hand, and was not gradient ascent / descent.
Let us suppose that we can calculate the gradient ( and hessian ) of f ( x, y ), my basic scheme is to try using standard gradient ascent ( or conjugate gradient, etc . ) many times with different random starting points to discover all mountains.
It's difficult to find gradient ascent in a sentence. 用gradient ascent造句挺难的

Kusner's half-way models are saddle points for Willmore energy, arising ( according to a theorem of Bryant ) from certain complete minimal surfaces in 3-space; the minimax eversions consist of gradient ascent from the round sphere to the half-way model, then gradient descent down ( gradient descent for Willmore energy is called Willmore flow ).
