NeuroShell 2 -------------------------------------------------------------------------------- NeuroShell 2 Main Page Neural Network Architectures Additional Features Graphics Aid Data Analysis Built-in Capabilities Use Network Outside of NeuroShell Specifications Included Features -------------------------------------------------------------------------------- NeuroShell 2 combines powerful neural network architectures, a Microsoft® Windows icon driven user interface, sophisticated utilities, and popular options to give users the ultimate neural network experimental environment. It is recommended for academic users only, or those users who are concerned with classic neural network paradigms like backpropagation. Users interested in solving real problems should consider the NeuroShell Predictor, NeuroShell Classifier, or the NeuroShell Trader. Beginner's Neural Networks NeuroShell 2 includes both Beginner's and Advanced Systems in addition to Runtime Facilities. NeuroShell 2 includes interfaces for beginners and experts alike. The Beginner's System in NeuroShell 2 is designed for novices and first-time users. It includes a simplified set of procedures for building and executing a complete, powerful neural network application. The Beginner's System uses our powerful enhanced backpropagation paradigm, and defaults network parameters such as learning rate, momentum, and number of hidden neurons. To use the system you enter data, specify the inputs and outputs, and train the network. You are then able to apply the trained network to new data and export the results to other programs. Advanced Neural Networks The NeuroShell 2 Advanced Options screen displays the independent modules that may be used to create a neural network application. click on image for a better picture The Advanced System in NeuroShell 2 gives experienced neural network users the ability to create and execute 16 different neural network architectures, with more user control compared to the Beginner's System. Spreadsheet Format Users can choose to enter their data in their familiar spreadsheet program or work in the NeuroShell 2 Datagrid. The program uses spreadsheet files as its internal format so you can view or edit them yourself. In fact, NeuroShell 2 will call your favorite Windows spreadsheet program. 32-Bit Addressing; 32-Bit Math NeuroShell 2 takes advantage of 32-bit addressing because it is a full 32-bit program that runs only on Windows 98, Windows 2000, XP or NT (with Service Pack 3). NeuroShell 2 operates with either 32-bit floating point or 32-bit integer arithmetic, depending upon whether or not your computer has a math coprocessor. For example, 486 SX machines do not have a math coprocessor, but NeuroShell 2 automatically switches to the fast and precise 32-bit integer arithmetic mode (actually, the arithmetic is 64 bits, with final storage in 32 bits). With any other software on such a machine, floating point would be very slow. File Import and Export NeuroShell 2 imports ASCII, binary, and spreadsheet files. The program imports and exports ASCII and binary file formats. The File Export Module allows you to convert NeuroShell 2 files to ASCII or binary files. It will also merge data into an existing spreadsheet or print a file. Data Preprocessing The Rules Module allows you to create If/Then/Else rules to pre-process data. The Symbol Translate module converts alphanumeric data or strings into numbers which can be processed by the network. For example, you may want to convert 'cold', 'warm', and 'hot' to 1, 2, and 3 respectively. The Rules Module allows you to create If/Then/Else type rules to preprocess data prior to feeding it to the network. For example, you can use two input variables to create a third. You may believe that if you combine the price of gold and IBM stock and the total is greater than 400, the economy is improving. You can translate this information into a new network input as follows: If gold + IBM > 400, then economy (the new variable) = 1, else economy =0. You may also use the Rules Module to post-process the network's predictions and classifications. Test Set Extract NeuroShell 2 gives you great flexibility in choosing which columns of your spreadsheet are inputs and which are outputs. click on image for a better picture NeuroShell 2 makes it easy to pull out test and production data sets from the training data. The Test Set Extract Module offers four different methods for selecting data: N percent randomly chosen. Every Nth pattern. Block designation. By row marker in the data. Combination block designation and random.
