Thinks Pro

TM ThinksPro^{^{^Ô}}

Neural Networks for Windows

The Professional Neural Network Development Environment

Intuitive, interactive and highly responsive user interface

Built-in spreadsheets for convenient editing of data. Sensitivity Analysis and Input Disabling speed the development of high performance neural networks.

Dynamic graphing and Visualization Tools to view inputs, states, weights and outputs continuously illustrate training progress

Industry standard, documented, field-proven algorithms, make ThinksPro the perfect tool for students and professionals.

The first to offer reinforcement learning for complex control and financial applications. User defined grading eliminates the constraint of the fixed training set.

ThinksPro contains the most sophisticated algorithms and capabilities available. ThinksPro provides multiple views into how neural networks learn and work. ThinksPro is the first to take you into the world of reinforcement learning with the EvalNet User Defined Grading Function and four graded learning algorithms, including the Temporal Difference Algorithm. ThinksPro comes standard with the following:

¨ Windows Dynamic Link Library (DLL)

Allows the professional user to build custom Windows, Visual Basic and Excel 5.0 applications.

¨ Sensitivity Analysis of Input Variables

Sensitivity Analysis facilitates the determination of the relative importance of the network inputs. Input disabling allows you to turn off unimportant inputs without reloading or rebuilding the training data.

¨ EvalNet User Defined Grading (DLL)

This allows the user to interactively test the network during the learning process. This allows ThinksPro to train networks for complex control applications or to maximize return on investment or any cost function in financial applications. This feature brings the full power of the ThinksPro visualization tools to your custom application.
