------------------------------------------------------ QwikNet32 v2.00 Copyright (C)1997 Craig Jensen ------------------------------------------------------ INTRODUCTION ------------ QwikNet is a powerful, yet easy to use artificial neural network simulator. QwikNet implements several different algorithms to train a standard feed- forward neural network in an easy-to-use graphical environment. The shareware version is limited to a maximum of 1 hidden layer with 10 hidden neurons and a maximum of 500 patterns per training data file. The registered version can accommodate up to 5 hidden layers with no limits (besides hardware) on the number of hidden neurons or training patterns. You may evaluate this software free for 30 days, after which you must either purchase the registered version or delete the software from your machine. Please feel free to distribute the file QwikNet32.ZIP to friends, associates, or to a computer bulletin board system (BBS). REGISTRATION ------------ There are two ways to register. You can print and fill out the registration form in the file 'register.txt', (also found in the help file), and mail it with your US cash/check payment directly to the author. Or you can register via Kagi Software by running the file 'register.exe' and following the instructions. Kagi accepts many different payment methods including credit cards and non-US funds. The registration fee is US $75. Upon receipt of payment you will receive the full registered version and all future upgrades for one year. INSTALLATION ------------ The 32-bit version, QwkNet32.EXE, requires a minimum 486 processor and Windows 95 or NT 4.0. This version removes all practical limits on network/data file size. A complete installation requires less than 3 MB of disk space. To install QwikNet32 unzip the file qwiknet32.zip and run the file setup.exe. EXAMPLE DATA FILES ------------------ Several example data files are included for testing: SINCOS.TRN - Training data file with one input (x) and two outputs Sin(x) and cos(x). SINCOS.TST - Testing data for SINCOS. SINCOS.WTS - Example of saved weights. SINCOS.NET - SINCOS project file. SECURITY.* - A more complex data set for Power System Security analysis. The data set contains 33 inputs (power system features) and 1 output (security classification). XOR.* - XOR training data set. Two inputs and 1 output. SPIRALS.* - The popular "Two spirals" data consisting of data coiled three times around the origin and around one another in the x-y plane. This is a very difficult task for back-propagation networks and their relatives. **** NOTE: Acceptable performance on the two spirals problem may be impossible given the limitations of the shareware version of QwikNet. A 3D contour map of the solved spirals problem is included in the QwikNet help file, it uses two hidden layers.
