skada.LinearOTMappingAdapter
- skada.LinearOTMappingAdapter(reg=1e-08, bias=True)[source]
Domain Adaptation Using Optimal Transport.
Uses Gaussian Monge mapping to align source and target domains as proposed in [7].
- Parameters:
- regfloat, (default=1e-08)
regularization added to the diagonals of covariances.
- bias: bool, optional (default=True)
estimate bias.
- Attributes:
- ot_transport_object
The OT object based on linear operator between empirical distributions fitted on the source and target data.
