Summary

Summary Bio

Programmer Analyst at FedEx Services.
On the side, I am most interested in Numenta. I agree that the only working model of intelligence is the neocortex. Biology has had more time and parallel trials, so has come up with this. Just as with other examples, biology has come up with a good working model. As pointed out in one of Hawkins talks, NuPIC (Numenta’s reverse engineered model of the neocortex as a computer program) is able to do well across a spectrum of problems with minimal training.
Most Recent Experience

I am working on trying to develop a Predictor-Corrector estimator using NuPIC and a Kalman Filter.
NuPIC will serve as the Predictor.

My other side project is to try to use NuPIC in financial quantitative analysis. I am trying to use NuPIC to optimize parameters for mortgage pre-payment models based on the Andrew Davison/Goldman-Saks/MIAC 5 factor prepayment model.
Previous Work Experience

My background is in CAD/CAM modeling at Intergraph, Mitsubishi Research, and Parametric Technology Corporation. I have worked on Constructive Solid Geometry to Boundary Representation conversion using STEP (Standardized Exchange of Parts).
I have also worked on Fractional Quantitative Invisibility (inspired by the notion of fractional charged subatomic particles) using Appel’s Algorithm in Hidden Line Removal using Mantyla’s data structures. In this algorithm, I used a method which exploited the image coherence and a weighted voting and backpropagation approach for error correction. I would also run Monte-Carlo simulations to try to optimize these weighting parameters.

Collaboration Opportunities

I am interested in developing financial models using NuPIC.
More specifically, I am trying to use NuPIC to optimize the 5 factors when refinancing a portfolio of mortgages.
