We defined the connectivity problem as an energy minimization task, by associating the DT-field to a physical system composed of nodes and springs, with their constants defined as a function of local structure. Using a variational approach we formulated a fast and stable map evolution, which......
(14.5). Finally, note that the kernel must be an even function of |x−x′|. The most commonly used smoothing kernel in practical applications is the Schoenberg cubic spline. Specifically, in one space dimension, the kernel can be written as follows (14.8)W(x,h)=16h{(2−s)3−4...

1.Taking the sample features of the object to be grasped and requirements for the task into consideration,we use the radial basis function(RBF) neural network with the Gaussian kernel function as its base function to represent the complex nonlinear mapping relationship between the grasp mode and ...
Do you want to use the Gaussian kernel for e.g. image smoothing? If so, there's a function gaussian_filter() in scipy: Updated answer This should work - while it's still not 100% accurate, it attempts to account for the probability mass within each cell of the grid. I think that ...

If the kernel size is too big for chosen sigma, then most part of the kernel has filter parameters close to 0. If we review the Gaussian function, we knew that if we choose a kernel size of 6*sigma, and the parameter at the centre is 1.0; then the value at the edge will be ...

These values were smoothed using robust loess regression (‘smooth.m’ function in MATLAB) with one third of the trials as the span, but the exact choice of smoothing window did not affect the results (Figure S3D ). We subtracted these values to estimate the baseline activity on each trial...
