WebApr 3, 2024 · Dot product of two sequences. Let x = ( x 1, x 2, ⋯) be an absolutely convergent sequence and y = ( y 1, y 2, ⋯) be any sequence where y i ∈ C. If y = ( y 1, y 2, y 3, ⋯) is not bounded then the dot product of two sequences does not converge? I thought about the example case. WebApr 10, 2024 · 1 So I have X and Y which are binary vectors of the two elements 0,1, and are about 30000 elements long. What I want to do exactly is find a fast way to calculate np.inner (X, Y)/np.sum (Y). I don't think much can be done about the np.sum (Y) part, which basically just counts how many 1s there are in Y.
