Neural network system adapted for non-linear processing

A neural network system comprising:

• first evaluation means for qualitatively analyzing unknown data supplied thereto;
• computing means, including a neural network having a plurality of neurons, for computing desired data from the qualitatively analyzed unknown data output from said first evaluation means, each neuron being connected through synapses to other neurons, each synapse being given a weight, each neuron outputting an output function value in accordance with a total sum of products of output function values from the connected neurons and synapse weights,
• wherein said computing means further includes:
• means for storing a network of qualitative causal relation between unknown and desired data, and
• network definition means for defining the neural network by connecting neurons through synapses in accordance with the qualitative causal network;
• and
• second evaluation means for quantitatively analyzing desired data received from said computing means and outputting the result of analysis.

A neural network system comprising:

• fuzzy means for fuzzy conversion of an unknown data supplied thereto;
• neural network means including a neural network having a plurality of neurons for computing the network output data from the unknown data fuzzy-converted by said fuzzy means, each neuron being connected through synapses to other neurons, each synapse being given a weight coefficient, each neuron being adapted to output an output function value assigned thereto associated with the total sum of the products of the output from the neurons connected and the synapse weight coefficient,
• wherein said neural network means further includes:
• means for storing a network of qualitative causal relation between unknown and desired data, and
• network definition means for defining the neural network by connecting neurons through synapses in accordance with the qualitative causal network;
• and
• defuzzy means for defuzzy-converting output data of said neural network means and outputting a desired data.
