tool
A graphical user interface for evaluating and interacting with the Aspirin neural network simulation.
Utilities exist for moving quickly from an Aspirin description of a network directly to an executable program for simulating and evaluating that network. MIGRAINES has been kept separate from Aspirin so that its limitations do not restrict the performance of Aspirin. However, in practice, they are used together. This combination allows for simple specification and creation of efficient neural network systems that can be graphically analysed and tested.
