Transfer learning aims at reusing the knowledge in some source tasks to improve the learning of a target task. Many transfer learning methods assume that the source tasks and the target task be related, even though many tasks are not related in reality. However, when two tasks are unrelated, the knowledge extracted from a source task may not help, and even hurt, the performance of a target task...

In this work we consider the following primitive, that we call restricted adaptive oblivious transfer. On the one hand, the owner of a database wants to restrict the access of users to this data according to some policy, in such a way that a user can only obtain information satisfying the restrictions imposed by the owner. On the other hand, a legitimate user wants to privately retrieve allowed...

Sentiment transfer aims at revising the input text to satisfy a given sentiment polarity while retaining original semantic content. The nucleus of lies in precisely separating information from content information. Existing explicit approaches generally identify and mask tokens simply based on prior linguistic knowledge manually-defined rules, leading low generality undesirable performance. In t...

In this paper, a newmodification term for use in adaptive control is developed to improve robustness of an existing design. The objective is to recover the loop transfer properties of a reference model associated with a nonadaptive control design. Consequently, this term can increase the level of confidence of an adaptive control system for purposes of increased flight safety. An illustrative e...

We study an adaptive variant of oblivious transfer in which a sender has N messages, of which a receiver can adaptively choose to receive k one-after-the-other, in such a way that (a) the sender learns nothing about the receiver’s selections, and (b) the receiver only learns about the k requested messages. We propose two practical protocols for this primitive that achieve a stronger security no...

Let 9 be a convex set of real polynomials. This paper considers the question of when there exists a real polynomial b(s), or more generally, a real transfer function b(s), such that p ( s ) / b ( s ) is strictly positive real for all p ( s ) E 9. Necessary and sufficient conditions are found for the transfer function b(s ) case, and when the degree of the polynomials in 9 is restricted, such co...
