Time Series Piecewise Linear Representation Method Based on First-order Filtering

For the time series whose slope fluctuation frequency is relatively fierce,time series piecewise algorithm with edge point extraction based on slope is easy to fall into local optimum.It cannot keep the overall features of original time series.For this problem,this paper proposes a Piecewise Linear...
