1)I know that k(x_,x_) = \sigma^2_, so if I simply take the gradient of \sigma^2_with respect to x_* twice, then I should recover \frac{d^2k(x_,x_)}{dx_*^2}, which is exactly equal to the expression in (9.1). When I do this: dkdx = np.gradient(sigma**2.,x[:...

Three features make this algorithm especially well suited to the MVEE problem: the gradient required at each iteration (to determine the most strongly violated constraint) can be updated in O(mn) operations rather than the \(O(m n^2)\) cost of computing a new gradient from scratch; the ...
2-dimensional 3x3 Sobel Magnitude Filter of RGBA image. Implemented in OpenCL for CUDA GPU's, with performance comparison against simple C++ on host CPU. Gradient magnitude for each of the R, G & B channels is computed concurrently and independently, then combined into a single gradient intensi...
This is the rationale for mixed precision training. The main version of the weight is stored in FP32 form. When doing inference and backpropagation operations, first replace it with FP16 for calculation. When doing weight update, the updated increment (gradient multiplied by the learning rate) ...
