We propose a blind image quality assessment that is highly unsupervised and training free. The new method is based on the hypothesis that the effect caused by distortion can be expressed by certain latent characteristics. Combined with probabilistic latent semantic analysis, the latent characteristics can be discovered by applying a topic model over a visual word dictionary. Four distortion-aff...

To explain how people judge that others are lying, an expectancy-violation model is proposed. According to the model, deception is perceived from nonverbal behavior that violates normative expectation. To test the model, 3 experiments were conducted, 2 in the United States and 1 in India. In each experiment, people described acquaintances while exhibiting weird nonverbal behaviors, such as arm ...

The credit default swap has become well-known as one of the causes of the 2007-2010 credit crisis but more research is vitally needed to analyze and define its impact more precisely and help the financial market transparency. This paper uses cartesian genetic programming as a discovery tool for finding the relationship between credit default swap spreads and debts and studying the arbitrage cha...

Do you have any strong views on journals and the peer review system? The peer review system isn’t perfect, but I think it will continue to be better than the alternatives as long as we have hardworking and judicious editors. It worries me that an increasing number of action letters appear to have been written by someone who hasn’t read the article, and just took a head count of reviewers in fav...

Visual event-related potentials were recorded from a group of 10 normal subjects while they judged the proximity of two letters of the alphabet. Subjects viewed singly the letters A, D, G, L, N, T, W and Z and indicated by button press whether the letter displayed occurred before or after the comparison letter M. Reaction times to close letters (L and N) were longer than ordinally more distant ...

The relationship between metacognition and mindreading was investigated by comparing the monitoring of one's own learning (Self) and another person's learning (Other). Previous studies indicated that in self-paced study judgments of learning (JOLs) for oneself are inversely related to the amount of study time (ST) invested in each item. This suggested reliance on the memorizing-effort heuristic...

This work contributes to the theory of judgment aggregation by discussing a number of significant non-classical logics. After adapting the standard framework of judgment aggregation to cope with non-classical logics, we discuss in particular results for the case of Intuitionistic Logic, the Lambek calculus, Linear Logic and Relevant Logics. The motivation for studying judgment aggregation in no...

There is good evidence that biological perceptual systems exploit the temporal continuity in the world: When asked to reproduce or rate sequentially presented stimuli (varying in almost any dimension), subjects typically err toward the previous stimulus, exhibiting so-called "serial dependence." At this stage it is unclear whether the serial dependence results from averaging within the perceptu...

In two studies, we investigated how people use base rates and the presence versus the absence of new information to judge which of two hypotheses is more likely. Participants were given problems based on two decks of cards printed with 0-4 letters. A table showed the relative frequencies of the letters on the cards within each deck. Participants were told the letters that were printed on or abs...

Four experiments explored the extent the extent to which abstract knowledge may underlie subjects' performance when asked to judge the grammaticality of letter strings generated from an artificial grammar. In Experiment 1 and 2 subjects studied grammatical strings instantiated with one set of letters and were then tested on grammatical and ungrammatical strings formed either from the same or a ...
