The submission is proposing a multi-task learning method based on sharing linear submodules. The proposed idea is interesting, novel, and shown to be effective. On the other hand, reviewers raised various issues about the empirical study. Authors did a good job addressing this issue in their response, and the final evaluation of all reviewers are positive. The paper is a good addition to the conference, and I recommend acceptance. Authors should add the promised experimental results in the camera-ready version.
