Webbution of similar classes cross domains. Third, we propose a Cosine Annealing Strategy (CPM-C) to support learning with CPM-S and CPM-A for achieving the optimal domain adaptation performance. To summarize, our contributions are as following: { For the rst time, we present an inductive unsupervised domain adaptation Web2.1 Cosine Annealing Better optimization schema can lead to better results. Indeed, by using a different opti-mization strategy, a neural net can end in a better optimum. In this paper, this is achieved by using Stochastic Gradient Descent with warms Restart (SGDR) [5]. In particular, the learning rate is restarted multiple times.
