Web2 Jun 2024 · To be specific, a rolling mean is a low-pass filter. This means that is leaves low frequency signals alone, while making high frequency signals smaller. Sharp increases in the data have a high frequency. If we make the kernel larger, the filter attenuates high frequency signals more. This is exactly how the rolling average works. Web15 Jan 2024 · Filtering is performed seperately for each channel in the input using a depthwise convolution. Arguments: channels (int, sequence): Number of channels of the input tensors.

June 8, 2024 Daniel Müller-Komorowska Leave a comment. Time series data may contain signals at many different frequencies. Sharp increases or decreases have a high frequency. Slow increases or decreases have a low frequency. Filtering allows us to take different frequency components out of the data.
