%description
Cooperative learning combines the usual squared error loss of predictions
with an agreement penalty to encourage the predictions from different data
views to agree. By varying the weight of the agreement penalty, we get a
continuum of solutions that include the well-known early and late fusion
approaches. Cooperative learning chooses the degree of agreement (or
fusion) in an adaptive manner, using a validation set or cross-validation
to estimate test set prediction error. In the setting of cooperative
regularized linear regression, the method combines the lasso penalty with
the agreement penalty (Ding, D., Li, S., Narasimhan, B., Tibshirani, R.
(2021) <doi:10.1073/pnas.2202113119>).
