The final optimization we make is to generalize the sorter to work on key/index pairs. Because the GPU processes four-vectors, we can pack two key/index pairs into one fragment. Because the last pass of each sorting stage only compares neighboring items (see Figure 46-3), this will ...
To get the impulse response of a Butterworth filter, we simply filter a vector of size NT with all zeros and a single 1 value at position floor(NT/2) (0-based indexing). Channel whitening While temporal filtering reduces time-lagged correlations coming from background electrical activity, it...
4(%rsi) correspond to two different memory locations. The symbol $2 is a placeholder for a constant value, which corresponds to the length of the vector in this example. We use the terms assembly program and assembly algorithm interchangeably in this work. This is because AlphaDev builds...
One measure of ``unsortedness'' in a sequence is the number of pairs of entries that are out of order with respect to each other. For instance, in the letter sequence ``DAABEC'', this measure is 5, since D is greater than four letters to its right and E is greater than one lette...
Given a vector x¯∈Bn, denote by x¯R‾ the vector obtained from x¯ by reversing and complementing each bit. For example, 100R‾=110. Lemma 8 Let C be a comparator network on n channels and CR be its reflection. Then x¯∈outputs(C) if and only if x¯R‾∈outputs...

The second step consists of computing the first principal component v1∈Rd, i.e., the vector along which the data {xi} exhibits largest empirical variance. This vector can be computed by a thin singular value decomposition of the tall-skinny data matrix X≔[x1,…,xn]T∈Rn×d, (1)X...
