PPM-Decay: A computational model of auditory prediction with memory decay

Fig 10

Illustrative weight decay profile.

This figure plots the weight of an n-gram of length one as a function of relative observer position, assuming that new symbols continue to be presented every 0.05 seconds. Model parameters are set to t_b = 2, n_b = 15, w₀ = 1.0, t_0.5 = 3.5, w₁ = 0.6, and w_∞ = 0, as optimized in Experiment 3.
