BION: ObjectivesBION: Objectives
> The main objective of the project is the realization of a new,highly innovative technology for the production of functionalmolecular assemblies, which can perform advanced tasksof information processing involving learning and decisionmaking, and which can be tailored down to the nanoscale.
> Project milestones
Fabrication and study of the nodes of the matrix, individuallyand in simple forms of the matrix; first application to abiological system.
Fabrication of the complex matrix:Alternative pathways
Transfer of data from biological systems and application ofArtificial Intelligence techniques

> Hebbian rule: When an axon of cell A is near enough to excite cell B andrepeatedly or persistently takes part in firing it, some growth process ormetabolic change takes place in one or both cells such that A's efficiency, asone of the cells firing B, is increased
Integration of processing and memory properties for the network elements
Learning procedure of the developed network must be based on combined learningparadigm (supervised and unsupervised learning)
Very high level of parallel processing
