Percolation threshold, Fisher exponent, and shortest path exponent for four and five dimensions.
We develop a method of constructing percolation clusters that allows us to build very large clusters using very little computer memory by limiting the maximum number of sites for which we maintain state information to a number of the order of the number of sites in the largest chemical shell of the cluster being created. The memory required to grow a cluster of mass s is of the order of s(strai...
متن کاملFinancial Probabilities from Fisher Information
We present a novel synthesis of Fisher information and asset pricing theory that yields a practical method for reconstructing the probability density implicit in security prices. The Fisher information approach to these inverse problems transforms the search for a probability density into the solution of a differential equation for which a substantial collection of numerical methods exist. We i...
متن کاملExpected classification error of the Fisher linear classifier with pseudo-inverse covariance matrix
The pseudo-Fisher linear classifier is considered as the ‘‘diagonal’’ Fisher linear classifier applied to the principal components corresponding to non-zero eigenvalues of the sample covariance matrix. An asymptotic formula for the expected Ž . generalization error of the Fisher classifier with the pseudo-inversion is derived which explains the peaking behaviour: with an increasing number of le...

متن کاملExponential Stability of the Traveling Fronts for a Pseudo-parabolic Fisher-kpp Equation
In this talk, I will introduce the stability of traveling front solutions for a pseudoparabolic Fisher-KPP equation. By applying geometric singular perturbation method, special Evans function estimates, detailed spectral analysis and C0 semigroup theories, all the traveling front solutions with non-critical speeds are proved to be locally exponentially stable in some appropriate exponentially w...
