Before revision:  We propose a new architecture as well as a two-stage learning algorithm that allows us to effectively share knowledge from multiple tasks while avoiding these crucial problems. In the first stage , we learn task specific parameters  that encapsulate the knowledge from each task .
After revision:  We propose a new architecture as well as a two-stage learning algorithm that allows us to effectively share knowledge from multiple tasks . First, in the knowledge extraction stage we learn task specific parameters that encapsulate the knowledge from each task .
