WebThe term ruling grade is usually used as a synonym for "steepest climb" between two points on a railroad, but if the steepest climb is, say, a quarter-mile of 1% preceded and … Web9 jun. 2024 · Let's define a t = v t / λ. The update rules are changed slightly as. at+1 = μ.at - ∇f (θt + μ.λ.at) θt+1 = θt + λ.at+1. (The motivation for this change in TF is that now a is a pure gradient momentum, independent of the learning rate. This makes the update process robust to changes in λ, a possibility common in practice but that the ...
