- - ai.libs.jaicore.ml.tsc.filter.transform.SineTransform

All Implemented Interfaces:

IFilter
```
public class SineTransform
extends ATransformFilter
```
Calculates the sine transform of a time series. For this implementation, the definition as given in "Non-isometric transforms in time series classification using DTW" by Tomasz Gorecki and Maciej Luczak (2014) is used. The sine transform f = {f(k): k = 1 to n} of a time series T = {T(i): i = 1 to n } is defined as f(k) = sum_{i=1}^{n} T(i) * sin[(PI/n)*(i-0.5)*k].
