torch_geometric.transforms.RandomShear

class RandomShear(shear: Union[float, int])

Bases: BaseTransform

Shears node positions by randomly sampled factors \(s\) within a given interval, e.g., resulting in the transformation matrix (functional name: random_shear).

\[\begin{split}\begin{bmatrix} 1 & s_{xy} & s_{xz} \\ s_{yx} & 1 & s_{yz} \\ s_{zx} & z_{zy} & 1 \\ \end{bmatrix}\end{split}\]

for three-dimensional positions.

Parameters:

shear (float or int) – maximum shearing factor defining the range \((-\mathrm{shear}, +\mathrm{shear})\) to sample from.
