GenSheet Excel-based genetic algorithm
toolkit for optimization
Genetic algorithms for
optimizing binary, integer, real, and permutation valued functions that you can create
on any Excel spreadsheet; includes commands for
constrained nonlinear optimization, classifiers, scheduling, and minimum
variance portfolio computation. Genetic algorithms are inspired by Darwinian evolution:
over time, an initial population of answers improve and converge to
a population of optimal answers.
NNetSheet Excel-based neural network
toolkit
Neural network algorithms for supervised learning
(perceptron, delta rule, generalized delta rule with back propagation)
and unsupervised learning (Hamming, Fuzzy Hamming, and Euclidean clustering).
Induce-It Excel-based case-based
reasoning system
Creates case-based reasoning
expert systems from Microsoft Excel spreadsheet databases. Induce-It
searches a case database based on
similarity metrics. Case-based are
adapted from the closest matching cases, ranked by case score, and displayed
to users in a sorted list.
Statistics
RunRandom Quasi-random number and vector
generation
A Random number generation tool and C/C++ library based on
Quasi-Random (Low Discrepancy Sequences) and Pseudo-Random vector
generation algorithms. Quasi-random numbers have better convergence properties
in many simulation applications. RunRandom includes high dimensional (up
to 5000 dimensions) generators for several
low discerepancy sequences.
RunPCA Principal components analysis
Principal component analysis useful for
reducing the complexity of high dimensional data: a high dimensional data set can
be approximated with fewer dimensions. PCA is used in datamining
and for pre-processing input data for neural networks and regression. RunPCA includes
a PCA application and C/C++ library.
KernelNet Kernel regression
Non-parametric
multivariate kernel regression
(also known as General Regression Neural Networks) is used for pattern
recognition and forecasting that is based on discovering the underlying probability density of
the observed data. KernelNet includes a kernel regression application and
C/C++ library. KernelNet uses a variation of Sliced
Inverse Regression (SIR) for dimension reduction
to improve efficiency.
Utilities

Financial Applications (In Beta)
Risk Kit
Tools and and C/C++ libraries
for Fixed-Income Risk Management and Trading. The Risk Kit integrates
valuation models of securities, interest rate, exchange rate, credit risk and
value at risk.
Server-Based Systems (In Beta)
Real-Time Analytics
RTA is a flexible computational architecture that
computes, sorts, and broadcasts real-time standard deviations, correlations, and hundreds
of other analytics for volatile portfolios. The RTA server is written in
Java and supports
multi-computer servers, authenticated access via smart cards, dynamic content rewriting
for hand-held devices, XML, and automatic session management.
ShowTheBest.Com
ShowTheBest
is a server-based system for website developers that transforms static tables into interactive forms.
It can access data through server files and server databases. It has a
fast and flexible scoring engine that is based on artificial intelligence concepts. By pressing a
button, visitors to a site can quickly see the
best (and worst) data records that match their requirements.
