 Dear Connectionists,

The link for the  paper  previously announced was wrong, the right one is :

Sorry about that.

 Abstract:
 
 We study the problem of determining the Hamiltonian of a fully connected
 Ising Spin Glass of $N$ units from a set of measurements, whose sizes
needs
 to be ${\cal O}(N^2)$ bits. The student-teacher scenario, used to study
learning
 in feed-forward neural networks, is here extended to 
 spin systems with arbitrary couplings.
 The set of measurements consists of data about the local
 minima of the rugged energy landscape.
 We compare simulations and analytical approximations for the resulting 
 learning curves obtained by using different algorithms.
