چکیده

We studied various approaches for the allocation of mortgage pools, a combinatorial optimization problem faced by nancial institutions that trade in mortgage-backed securities. We review the problem, describe and compare the approaches taken to solve it, and demonstrate how this work motivates further research and the development of a high-level parallel rule language that uses metarules for redaction of connicting (or less prootable) instantiations.

The ALEXSYS Mortgage Pool Allocation Expert System: A Case Study of Speeding Up Rule-based Programs

It is frequently the case, however, that rule-based systems are used for rapidly prototyping knowledge-based applications, but then are reimplemented in more efficient imperative languages to improve the speed of operation of the final delivered product. A number of researchers, however, including us, have been studying an alternative path to speeding up rule-based systems by means of parallel ...

AlexSys: a knowledge-based expert system for multiple sequence alignment construction and analysis

Multiple sequence alignment (MSA) is a cornerstone of modern molecular biology and represents a unique means of investigating the patterns of conservation and diversity in complex biological systems. Many different algorithms have been developed to construct MSAs, but previous studies have shown that no single aligner consistently outperforms the rest. This has led to the development of a numbe...

A directional-based branches current method for transmission loss allocation in the pool-based electricity market

This paper proposes a new method for transmission loss allocation. The share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. Then, it is applied to the total network transmission lines. In the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introd...

Forthcoming: Journal of Real Estate Finance and Economics Unobservable Heterogeneity and Rational Learning: Pool Specific vs. Generic Mortgage-Backed Security Prices

Previous mortgage prepayment and valuation models assume that two mortgage pools with the same observable characteristics should behave indistinguishably. However, even pools with apparently identical characteristics often exhibit markedly different prepayment behavior. The sources of this heterogeneity may be unobservable, but we can infer information about a pool from its prepayment behavior ...
