pyinterp.fill.loess#
- pyinterp.fill.loess(mesh: Grid2D | Grid3D, nx: int = 3, ny: int = 3, value_type: str | None = None, num_threads: int = 0)[source]#
Filter values using a locally weighted regression function or LOESS. The weight function used for LOESS is the tri-cube weight function, \(w(x)=(1-|d|^3)^3\).
- Parameters:
mesh – Grid function on a uniform 2-dimensional grid to be filled.
nx – Number of points of the half-window to be taken into account along the X-axis. Defaults to
3
.ny – Number of points of the half-window to be taken into account along the Y-axis. Defaults to
3
.value_type – Type of values processed by the filter. Supported are
undefined
,defined
,all
. Default toundefined
.num_threads – The number of threads to use for the computation. If 0 all CPUs are used. If 1 is given, no parallel computing code is used at all, which is useful for debugging. Defaults to
0
.
- Returns:
The grid will have NaN filled with extrapolated values.
