PPM-Decay: A computational model of auditory prediction with memory decay
Fig 9
Schematic figure of accumulating observations within a memory buffer.
Weights for the n-gram “AB” are displayed as a function of time, assuming an itemwise buffer capacity (nb) of 5, a buffer weight (w0) of 1.5, an initial post-buffer weight (w1) of 1, a half life (t0.5) of 1 second, and an asymptotic post-buffer weight (w∞) of 0.
