Automatic Subjective Question Answering (ASQA), which aims at answering users’ subjective questions using summaries of multiple opinions, becomes increasingly important. One challenge of ASQA is that expected answers for subjective questions may not readily exist in theWeb. The rising and popularity of Community Question Answering (CQA) sites, which provide platforms for people to post and answ...

We consider the problem min{f(x) : x E G, T(x) tI. int D}, where fis a lower semicontinuous function, G a compact, nonempty set in JRn, D a closed convex set in JR2 with nonempty interior, and T a continuous mapping from JRn to JR2. The constraint T( x) tI. int D is areverse convex constraint, so the feasible domain may be disconnected even when f, T are affine and G is a polytope. We show that...

Great success has been achieved in the area of unsupervised domain adaptation, which learns to generalize from labeled source unlabeled target domain. However, most existing techniques can only handle closed-set scenario, requires both and have a shared category label set. In this work, we propose two-stage method deal with more challenging task open set where contains categories unseen Our fir...

The aim of unsupervised domain adaptation is to leverage the knowledge in a labeled (source) improve model’s learning performance with an unlabeled (target) domain—the basic strategy being mitigate effects discrepancies between two distributions. Most existing algorithms can only handle closed set (UCSDA), i.e., where source and target domains are assumed share same label set. In this article, ...

The existing iris recognition methods offer excellent performance for known classes, but they do not consider the rejection of unknown classes. It is important to reject an object class a reliable system. This study proposes open-set based on deep learning. In method, by training network, extracted features are clustered near feature centre each kind image. Then, authors build open-class outlie...

We consider convex sets and functions over idempotent semifields, like the max-plus semifield. We show that if K is a conditionally complete idempotent semifield, with completion K̄, a convex function Kn → K̄ which is lower semi-continuous in the order topology is the upper hull of supporting functions defined as residuated differences of affine functions. This result is proved using a separation...
