... the magnetic-force microscope(MFM), enables us to look at the actual performance of such heads-the definition, uniformity and strength of the magnetic field they produce. In place of the tungsten or silicon needle, the MFM has a magnetized nickel on probe. When the vibrating probe is brought near a magnetic sample, the tip feels a force that changes its resonance frequency and hence its vibration amplitude. The MFM can trace the magnetic-field pattern emanating from data-recording heads at a resolution of better than 25 nanometers. The device can also study the structure of the magnetic bits that store data on disks and other media, giving insight into both head performance and the quality of the storage medium.

A number of different variants trace their ancestry back to Hebb. Perhaps the simplest version is : When unit A and unit B are simultaneously excited, increase the strength of the connection between them. A natural extension of this rule to cover the positive and negative activation values is : Adjust the strength of the connection between units A and B in proportion to the product of their simultaneous activation. For simplicity of reference, we will call this the Hebb rule.

DEF

Règle d'apprentissage (selon laquelle) le poids d'une connexion est augmenté, si pour la nouvelle association, les unités reliées par cette connexion ont une activité de même signe, et diminué si pour la nouvelle association les unités ont une activité de signe contraire.

CONT

La règle de Hebb est le premier mécanisme d'évolution proposé pour les synapses. Son interprétation pour les réseaux de neurones formels est la suivante : on considère que si deux neurones connectés entre eux sont activés au même moment, la connexion qui les relie doit être renforcée. Dans les cas contraires, elle n'est pas modifiée.
