Data Denoising with Backward Moving MedianΒΆ

Causal Step - Outlier-Resistant Step

The step applies the Backward Moving Median algorithm to denoise one-dimensional time series data. Note that the algorithm does not need the timestamp information to denoise the data.

Input Parameters

  1. One-dimensional time series data
  2. Filter width

Output Parameters

  1. Denoised time series data
