- skada.ClassRegularizerOTMappingAdapter(reg_e=1.0, reg_cl=0.1, norm='lpl1', metric='sqeuclidean', max_iter=10, max_inner_iter=200, tol=1e-08)[source]
Domain Adaptation Using Optimal Transport.
See [6] for details.
- Parameters:
- reg_efloat, default=1
Entropic regularization parameter.
- reg_clfloat, default=0.1
Class regularization parameter.
- normstr, default="lpl1"
Norm use for the regularizer of the class labels. If "lpl1", use the lp l1 norm. If "l1l2", use the l1 l2 norm.
- metricstr, optional (default="sqeuclidean")
The ground metric for the Wasserstein problem
- max_iterint, float, optional (default=10)
The minimum number of iteration before stopping the optimization algorithm if it has not converged
- max_inner_iterint, float, optional (default=200)
The number of iteration in the inner loop
- tolfloat, optional (default=10e-9)
Stop threshold on error (inner sinkhorn solver) (>0)
