Numerous experiments with deep neural networks, where the representation learned on a source task is transferred to learn a target neural network, have shown the benefits of the approach. This paper, similarly, deals with hypothesis transfer learning. However, it presents a new approach where, instead of transferring a representation, the source hypothesis is kept and this is a translation from the target domain to the source domain that is learned. In a way, a change of representation is learned. We show how this method performs very well on a classification of time series task where the space of time series is changed between source and target.en0302-9743Lecture notes in computer science2020119131BoostingTransfer learningTransfer Learning by Learning Projections from Target to SourceConference Paper10.1007/978-3-030-44584-3_10Conference Paper
