Lecture 5: Stochastic Gradient Descent - Cornell University
www.cs.cornell.eduStochastic gradient descent (SGD).Basic idea: in gradient descent, just replace the full gradient (which is a sum) with a single gradient example. Initialize the parameters at some value w 0 2Rd, and decrease the value of the empirical risk iteratively by sampling a random index~i tuniformly from f1;:::;ng and then updating w t+1 = w t trf ~i t ...
The Method of Steepest Descent - USM
www.math.usm.eduThen the steepest descent directions from x k and x k+1 are orthogonal; that is, rf(x k) rf(x k+1) = 0: This theorem can be proven by noting that x k+1 is obtained by nding a critical point t of ’(t) = f(x k trf(x k)), and therefore ’0(t) = r f(x k+1) f(x k) = 0: That is, the Method of Steepest Descent pursues completely independent search ...

AC 120-108 - Continuous Descent Final Approach
www.faa.govThe descent rate remains at 632 fpm at 120 kts from the table (see Appendix 1, Figure 3). (3) Conclusion. If a pilot descends at 120 kts from 2,000 ft, beginning 5.9 NM from the runway threshold at a 632 fpm descent rate, the aircraft should cross the stepdown fix at 768 ft and the threshold at 46 ft.

ocw.mit.eduIf x =¯x is a given point, f(x) can be approxi-mated by its linear expansion f(¯x+ d) ≈ f(¯x)+∇f(¯x)T d if d “small”, i.e., if d is small. Now notice that if the approximation in the above expression is good, then we want to choose d so that the inner product ∇f(¯x)T d is as small as possible. Let us normalize d so that d =1.
