The Leave - one - out

The Leave-One-Out Kernel

Recently, several attempts have been made for deriving datadependent kernels from distribution estimates with parametric models (e.g. the Fisher kernel). In this paper, we propose a new kernel derived from any distribution estimators, parametric or nonparametric. This kernel is called the Leave-one-out kernel (i.e. LOO kernel), because the leave-one-out process plays an important role to comput...

Can we really rule out the existence of antistars?

The existence of large domains of antimatter is still an open question. Some space mission and experiments in the near future are expected to give reasonable answer to that question. Meanwhile, we can try to search for other signatures of the presence of antimatter. This paper presents a discussion about possible effects of the close encounter of stars and antistars. It is known that the accret...

How can we enhance the value of laboratory tests?

Today, the pressures on the healthcare systems for the controlling of the costs are extreme and all sectors try to demonstrate the value of their services by justifying the activities and expenditures so the value can be describe in terms like quality, efficiency, effectiveness, patient satisfaction, cost effectiveness .The value of the lab testing is generally directed to their costs and the c...

We can work it out: an enactive look at cooperation

The past years have seen an increasing debate on cooperation and its unique human character. Philosophers and psychologists have proposed that cooperative activities are characterized by shared goals to which participants are committed through the ability to understand each other's intentions. Despite its popularity, some serious issues arise with this approach to cooperation. First, one may ch...
