Intelligent simulation analysis method and system
First Claim
1. A computer-implemented method for calculating pricing information of a financial instrument comprising a plurality of underlying financial instruments, the method comprising:
- calculating in a computer system, a default time vector for each of a plurality of default scenarios wherein each default time vector includes a measure of a likelihood of default for each of said plurality of underlying financial instruments;
calculating in the computer system, one or more cash flows for a subset of said default scenarios;
training in the computer system, a neural network with said subset of said default scenarios, wherein the calculated cash flows for the subset of default scenarios are used as output training vectors for the neural network and the calculated default time vectors for each default scenario within the subset of default scenarios are used as input training vectors for the neural network; and
using said trained neural network in the computer system, to estimate one or more cash flows for a remaining number of said plurality of default scenarios.

Abstract
A method for calculating pricing information for a financial instrument consisting of a plurality of underlying financial instruments that includes the steps of: calculating a default time vector for a plurality of default scenarios wherein each default time vector includes a measure of a likelihood of default for each of the plurality of underlying financial instruments; calculating one or more cash flows for a subset of the default scenarios thereby forming a training set; training a neural network with the training set; and using the neural network to estimate one or more cash flows for a remaining number of the plurality of default scenarios.
