Mutual information is a metric from the joint (2D) histogram. The metric is high when the signal is highly concentrated in few bins (squares), and low when the signal is spread across many bins (squares). Mutual information is defined as: C1(dV1/dt)+g(V1) = (V2-V1)/R C2(dV2/dt) +(V2-V1)/R = I L(dI/dt) +rI+V2=0. I V2 V1 R R. n. r C2 C1 L. Chaotic signal to mask information.

The choice of m and τ should base on methods for detecting the optimal values of these two parameters like method of false nearest neighbours, fnn (for m) and mutual information, mi (for τ), which ensures the entire covering of all free parameters and avoiding autocorrelated effects (e.g. Kantz and Schreiber, 1997). Deﬁnition The mutual information between two continuous random variables X,Y with joint p.d.f f(x,y) is given by I(X;Y) = ZZ f(x,y)log f(x,y) f(x)f(y) dxdy.
