Tuning to an optimal stimulus is a widespread property of neurons in cortex. We propose that such tuning is a consequence of normalization or gain control circuits. We also present a biologically plausible neural circuitry of tuning.

Abstract: Global economic and social development has been severely inhibited by the COVID-19 outbreak. The long-term closure of sectors resulted in numerous losses presents a great challenge for many industries recovering their losses. Pandemics are not generally covered insurance takaful companies because outbreak disease on global level is rare event that requires substantial amount capital t...

This study explains the history, current problems, and future possibilities of Islamic insurance (takaful) in Bangladesh. To articulate these issues, the researcher has adopted the qualitative method, and data has been collected through secondary sources i.e. articles, books, and online resources. The study reveals that Islamic insurance in Bangladesh is regulated by the Insurance Act 2010 whic...

When an insurance company sells a mutual fund with death and maturity guarantees to its client, it may consider allowing the client to extend the guarantee for some more years. If the renewal only happens once, a so-called rollover option is implied in the contract. In this paper, we show how the generalized Bermudan option can be applied to the special case of the rollover option. By avoiding ...

We develop a theoretical analysis of generalization performances of regularized leastsquares on reproducing kernel Hilbert spaces for supervised learning. We show that the concept of effective dimension of an integral operator plays a central role in the definition of a criterion for the choice of the regularization parameter as a function of the number of samples. In fact a minimax analysis is...
