PPM-Decay: A computational model of auditory prediction with memory decay
Fig 2
Illustrative plots for Experiment 1.
A) Example sequence-generation models as randomly generated in Experiment 1. The bar plots describe 0th-order symbol distributions, whereas the matrices describe 1st-order transition probabilities. B) Repeated-measures plot indicating how predictive accuracy for individual sequences (N = 500, hollow circles) increases after the introduction of an exponential-decay kernel. C) Absolute changes in predictive accuracy for individual sequences, as summarised by a kernel density estimator. The median accuracy change is marked with a solid vertical line.
