摘要：
A new approach is introduced for analysing the dynamical properties of nonuniform attractors. Semi-local Lyapunov exponents and metric entropy are estimated for different regions in the phase space. Moreover, a systematic probing of the semi-local entropy as a function of time allows one to obtain the variation of predictability on the attractor. The relevance of the approach is discussed for some physiological time series.
