Abstract: According to an embodiment, a regression analysis is performed on a subset of a dataset, where the subset of the dataset corresponds to inputs from a first row of a matrix of sensors at a time instant k. The regression analysis generates a set of coefficients. A filter transform, to be applied on the subset of the dataset, is determined based on a comparison between the set of coefficients and threshold values. The filter transform can be one of an infinite impulse response (IIR) filter transform, a first-order filter transform, or a second-order filter transform. Once the filter transform is determined, it is applied to the subset of the dataset to generate a first output matrix.
