WebMar 7, 2024 · The convolution is obtained by putting the kernel in front of every area of the picture, like a sliding window, then do the element-wise product of the values in our kernel by the ones in the ... WebA simple way to achieve this is by using np.convolve.The idea behind this is to leverage the way the discrete convolution is computed and use it to return a rolling mean.This can be done by convolving with a sequence of np.ones of a length equal to the sliding window length we want.. In order to do so we could define the following function:
WebThis paper proposes a data anomaly detection and correction algorithm for the tea plantation IoT system based on deep learning, aiming at the multi-cause and multi-feature characteristics of abnormal data.
