, the improved model is capable of discovering the correlation between blobs (segmented regions) and textual keywords so as to automatically generate keywords for un-annotated image according to joint probabilities. Moreover, it has the ability to detect and remove false keyword(s) by considering the co-occurrence of
This paper presents method for split-step backward Euler scheme in regime-switching models. We generalize the classical Black-Scholes model to encompass regime-switching properties. The Black-Scholes model is shown to generate significant pricing errors when a regime-switching process governs underlying asset returns. In addition, regime-switching option values are shown to generate implied volatility...
