Nettet10. apr. 2024 · To compute the moving average or running mean with Python NumPy, we can use the SciPy uniform_filter1d method. For instance, we write import numpy as np from scipy.ndimage.filters import uniform_filter1d N = 1000 x = np.random.random (100000) y = uniform_filter1d (x, size=N) to create a array with x = np.random.random … Nettetdef moving_average (x, w): return np.convolve (x, np.ones (w), 'valid') / w. This function will be taking the convolution of the sequence x and a sequence of ones of length w. Note that the chosen mode is valid so that the convolution product is only given for …
