Abstract We consider the black hole information problem in an explicitly defined spacetime modeling evaporation. Using this context we review basic aspects of problem, with a particular effort to be unambiguous about subtle topics, for instance precisely what is meant by entropy various circumstances. then focus on questions unitarity, and argue that commonly invoked semiclassical statements lo...

Two distinct design problems of information display for process control are information content representation and visual form design. Regarding information content, we experimentally showed the effectiveness of functionally abstracted information without the benefits of sophisticated graphical presentation in various task situations. However, since it is obvious that the effects of the informa...

A content-based recommender system suggests items similar to those previously liked by a user, therefore the recommendation process consists of matching up the features stored in a user profile with those of a content object (item). Usually a content-based user profile stores keywords that are more meaningful for that specific user. Common-sense knowledge could positively enrich that profile an...

In recent years supervised representation learning has provided state of the art or close to the state of the art results in semantic analysis tasks including ranking and information retrieval. The core idea is to learn how to embed items into a latent space such that they optimize a supervised objective in that latent space. The dimensions of the latent space have no clear semantics, and this ...

This study examines the impact of peers’ previous cautious versus risky choices on adolescents’ risk-taking depending level information about risk. Adolescents completed an adaptation BART that manipulated social influence (cautious and risky) risk (i.e., informed, noninformed). Results showed impacts decisions noninformed but not informed BART. In BART, strongly decreased led to greater perfor...

Today, social networking has become a popular web activity, with a large amount of information created by millions of people every day. However, the study on effective searching of such social information is still in its infancy. In this paper, we focus on Twitter, a rapidly growing microblogging platform, which provides a large amount, diversity and varying quality of content. In order to prov...

| To prevent moving shadows being misclassiied as moving objects or parts of moving objects, this paper presents an explicit method for detection of moving cast shadows on a dominating scene background. Those shadows are generated by objects moving between a light source and the background. Moving cast shadows cause a frame diierence between two succeeding images of a monocular video image sequ...
