Effects of pattern bias on retrieval dynamics in and Hopfield networks

The effects of pattern bias on the retrieval of patterns stored in -1,1 and 0,1 Hopfield networks is examined. Pattern bias is the relative proportion of -1 and 1 pattern bits. We find both analytically and via numerical simulation, that -1,1 networks are not affected by pattern bias. In contrast, 0,1 networks will form asymmetric basins of attraction for a pattern and its inverse depending on the net bias of all stored patterns.
