approx_fprime(xk, f, epsilon, *args) Finite-difference approximation of the gradient of a scalar function. bracket(func[, xa, xb, args, grow_limit, ...]) Bracket the minimum of the function. check_grad(func, grad, x0, *args, **kwargs) Check the correctness of a gradient function...
How to Find the Slope of a Perpendicular Line Perpendicular Line Slope Examples Lesson Summary Slope of a Line Formula Slope, also called the gradient or rate of change, is a value that describes how steep a line is and the direction of the line. Slope is used in algebra to find the an...
In contrast to its gradient-based role model, the sEMD is spike-based. It translates the time-to-travel of a spatiotemporally correlated pair of events into a direction-dependent output burst of spikes. While the sEMD provides OF estimates with higher precision when the entire burst is ...
These families of curves can be used to control the values of a function in terms of its gradient (suitably interpretedon a general metric space), and to derive Sobolev and Poincar茅 inequalities.S. SemmesSelecta Mathematica,New SeriesSemmes, S.: Finding curves on general spaces through ...
grade - level to the right gradient strickle, strike - smooth with a strickle; "strickle the grain in the measure" strickle - level off with a strickle in a measuring container; "strickle sand"4.level - direct into a position for use; "point a gun"; "He charged his weapon at me...

Finding Tiny Faces Peiyun Hu, Deva Ramanan Robotics Institute Carnegie Mellon University {peiyunh,deva}@cs.cmu.edu Figure 1: We describe a detector that can find around 800 faces out of the reportedly 1000 present, by making use of novel characterizations of scale, resolution, and context to...
line, use pdist2() to find out which pair of points (P1b on the line and P2 on the next, expanded or shrunken curve) has the minimum distance. Basically you're finding out which point P2 corresponds to point P1a on the original curve and in a direction specified by the ...
(i.e. the gradient is zero) you have a stationary point. In short: find the 1 st differential, put it equal to zero and solve. Examples: Find the stationary point on the curve : Step 1: Differentiate to give: Step 2: Put this equal to zero: Step 3: Solve: We now ...
Single cell trajectories in time-lapse movies were analyzed using Gradientech Tracking Tool™ v1.07 software (Gradientech). Only cells initially at the migrating front were considered for analysis. The directness index is a measure of the cell directionality and is calculated by comparing euclidean...
