| Research Abstract |
The Brain is the best computer that we know. If we can understand and simulate the principle of its information processing, we will be able to make a computer that is completely different from those we have now. This is the aim of our project. It is classified into the following three parts. 1. The research of a single neuron.
The nature of the pulse trains that travl on nerve fiber is studied in terms of the reaction-diffusion equation. A new topological characteristic is defined, and it is shown to have a close relation with the stability of the pulse trains.
2. The research of neural networks.
A special kind of nerve field is studied that has the ability to learn the topology of the set of input signals. Under some condition the continuous mapping between the set of input signals and the field is unstable. in which case, it is shown, a kind of block structure is formed that reminds us of the columnar structure in the brain. Boltzmann machine, which is a thermo-dynamocal model of neuron networks, is also stukied theoretically.
3. The research of algorithms.
A new parallel processing algorithm is proposed to extract the orientation and the motion of a surface.
