The conditional entropy is used to assess the generalized synchronization of bidirectionally coupled chaotic systems. By increasing the coupled strength, the generalized synchronization appears when there is a sharp minimum of the conditional entropy. We apply this criteria to the case of the coupled Rssler-Lorenz an d Rssler-Rssler system to test our method. Numerical results show that it is very effective and robust.
