You've asked for it, so we've made it for you!
Our users are very impressed with our NeuroShell Predictor and Classifier neural networks, including Turboprop 2. We're not surprised. We spent over three years of research building these powerful, state-of-the-art neural network algorithms. So, at your request, we're now selling a product that will allow you to embed these neural networks, including training, into your own programs.
The new product is called the NeuroShell Engine. It is an Active X control that can be loaded into your Visual Basic, C++, or C# programs to bring the neural network power of the NeuroShell Predictor and Classifier to your programs. Incorporating the best neural networks on the planet is a piece of cake!
The NeuroShell Engine is a product that most of our users will never need, because our other programs allow you to call your networks from computer programs you write. Such computer programs can be distributed throughout your company and to your customers. If you purchase the NeuroShell Predictor or NeuroShell Classifier, you simply have to purchase the NeuroShell Runtime Server in order to place calls to your nets into your Windows programs written in Visual Basic, C++, Delphi, and other languages. If you purchase NeuroShell 2, it includes a runtime server so you can call your programs from the aforementioned languages in Windows, and you can also generate source code so your nets can be compiled on mainframes or Unix workstations.
So why do we sell the NeuroShell Engine? In case you want to embed the TRAINING portion of the process into your Windows programs. Let us explain further.
Use of neural nets involves two stages:
Stage 1, TRAINING. In this stage, the historic or sample observations are collected to build the neural model. The process is called training, where the neural net "learns" the sample observations. The end result is a model that can be used in stage 2.
Stage 2, FIRING (executing). In this stage, the model built in stage 1 is called (or "fired") to produce answers for new input data, data that was normally not used in stage 1 to build the model. This is the production environment where you utilize the model to make predictions, classifications, or other decisions.
Of course, our programs (NeuroShell Predictor, NeuroShell Classifier and NeuroShell 2) provide both stage 1 and stage 2 in them in graphical user interfaces. However, only stage 2 can be controlled from within your own computer programs written by your own programmers. (NeuroShell 2 includes this capability; NeuroShell Predictor and Classifier require the Runtime Server.)
Stage 1, in all of our other products, is accomplished only from a graphical user interface that is built into our products. That's where the NeuroShell Engine comes in. The Engine lets you call stage 1 (training) from your computer programs. In essence, it allows you to build your own neural network products for distribution! You can build custom designed neural network product interfaces too, by dropping our engine into your chassis.
II. What is the NeuroShell Engine
The NeuroShell Engine is only for the most serious neural network users, and only those who are programmers or have programmers on staff. The NeuroShell Engine contains the
neural and genetic training methods that we have used ourselves in the NeuroShell
Predictor, the NeuroShell Classifier, and the NeuroShell Trader. They are available to be
integrated into your own computer programs for both training and firing neural networks.
Basically there are four algorithms:
1. the neural method (Turboprop 2) used in the Predictor and Trader
2. The genetic method (Advanced GRNN) used in the Predictor
3. The neural method (Turboprop 2) used in the Classifier
4. The genetic method (Advanced PNN) used in the Classifier
III. Technical Details
If you are not a programmer, you will probably not understand the following description.
The NeuroShell Engine is an Active X control which can be utilized in modern compilers
like Microsoft Visual Basic and Microsoft Visual C++. The control can be added to a
program just as other controls are added, like combo boxes and text boxes. Once the
control is added to a program, the programmer can create "neural network" objects that
can be trained and fired. Neural Network objects have properties and methods. The properties
allow access to parameters of the neural networks you build, like the number of inputs, maximum
number of hidden neurons, etc. The methods facilitate training and firing of the neural network.
All of these things are accessed and manipulated from within your programs.

Visual Basic Program:

Methods and Properties
The NeuroShell Engine allows you to set the following methods and properties:
Calculates the Receiver Operating Characteristic (ROC) curve and the area under it.
Converts neural network classification probabilities into binary 0/1 numbers and creates an array
of winner indexes

IV. Licensing and Pricing
Please don't look for this engine to be inexpensive like most of our products have always
been. We're letting you have the crème de la crème of neural network modeling, the
technological heart of our most powerful products. If you aren't a very serious user, you
will not want to pay the price for serious networks. We aren't talking about the classic
"backprop" neural network paradigms that every college student learns. If you
are looking for an inexpensive solution, we recommend backprop, which is not in the
There will be two different types of licenses:
1. Internal use only license. With this license, you can use the
NeuroShell Engine in all programs which you intend to distribute only within your company
or government agency. There will be no restrictions of what type of program you may build,
but the license will not allow it to be used by anyone but your own employees. All of your
programmers in one physical location may use the software.
2. External use license. With this license, which will be the more
expensive of the two, you may use the NeuroShell Engine in a specified program which you
intend to sell or otherwise distribute outside of your company or government agency. We
must approve the program to be sure that it does not directly compete with any of our
products. Once your application program is approved, you may embed our technology and sell
or distribute the program with no royalty payments. All of your programmers working on
your application may use the software.
The Engine is not sold as an off-the-shelf product as our other software is. It sold with a
license agreement between Ward Systems Group and your company. Therefore, it is only sold by our
CEO, Marge Sherald, and she does not sell or discuss it via email. Please
call her at 301-662-7950 to discuss pricing and all other issues related to the Engine.
Note to Contract Programmers
The NeuroShell Engine contains Cadillac nets and it goes for Cadillac prices. However, if
you desire to use the NeuroShell Engine in a system for single clients, you do not have to
buy the more expensive distribution license. You get your client(s) to purchase the
internal license, and then you are a contractor just using their engine. Furthermore, we
will pay you a 20% sales commission upon their full price purchase!
