oineus.diff.weak_alpha_filtration(points, print_time=False)[source]¶

Build a differentiable weak-alpha filtration from a point cloud.

Parameters:

points – (n, d) torch.Tensor with d in {2, 3}. Differentiable.
print_time (bool) – If True, print per-stage timings.

Returns:

DiffFiltration whose values are squared longest-edge lengths.
