RWKV: Reinventing RNNs for the Transformer Era
Bo Peng, Eric Alcaide, Quentin Anthony +31
Transformers have revolutionized almost all natural language processing (NLP) tasks but suffer from memory and computational complexity that scales quadratically with sequence leng…
Optimal reinsurance design under solvency constraints
Benjamin Avanzi, Hayden Lau, Mogens Steffensen
We consider the optimal risk transfer from an insurance company to a reinsurer. The problem formulation considered in this paper is closely connected to the optimal portfolio probl…
On the optimality of joint periodic and extraordinary dividend strategies
Benjamin Avanzi, Hayden Lau, Bernard Wong
In this paper, we model the cash surplus (or equity) of a risky business with a Brownian motion. Owners can take cash out of the surplus in the form of "dividends", subject to tran…
Optimal periodic dividend strategies for spectrally negative Lévy processes with fixed transaction costs
Benjamin Avanzi, Hayden Lau, Bernard Wong
Maximising dividends is one classical stability criterion in actuarial risk theory. Motivated by the fact that dividends are paid periodically in real life, div…
Optimal periodic dividend strategies for spectrally positive Lévy risk processes with fixed transaction costs
Benjamin Avanzi, Hayden Lau, Bernard Wong
We consider the general class of spectrally positive Lévy risk processes, which are appropriate for businesses with continuous expenses and lump sum gains whose timing and sizes ar…
