A novel model is presented to address the problem of semantic clustering of geo-objects in very high resolution panchromatic satellite images. The proposed model combines a probabilistic topic model with a multiscale image representation into an automatic framework by embedding both document and scale selections. The probabilistic topic model is used to characterize the statistical distributions of...
This paper use the option pricing theory, based on the risk of default under the mortgage related to pricing model. Mortgage loan risk compensation will be converted to put option with the different strike price.
According to current commercial bank management requirements of credit risk, this paper studies the optimization allocation model of incremental economic capital of credit businesses in commercial bank. It has the objective function of Economic Value Added (EVA) and the restrictive conditions of hurdle rate, risk adjusted return on capital (RAROC), available economic capital gross, degree of concentration...
Parameter estimation of water quality model is generally obtained through the comparison of measured histories and model predictions of water bodies. In this paper, we present a new calibration tool of solving the parameter estimation problem by using particle swarm optimization (PSO) technique, which is a swarm intelligence method developed to perform heuristic direct search in a continuous parameter...
