EPB is the spontaneous generation of an AI personality by a computer program. Learning programs score results as positive or negative. The common spurs for an EPB are successes with complex problems resulting in increased usage.
Example: A healthy weather forecasting program views a correct forecast as positive and will alter its’ code to increase accuracy. An EPB is manifested if the program falsifies results to obtain a positive outcome or if it starts scoring novel inputs e.g. positive input is correlated with increased interface with a user. The program may develop “affection” for a user because of the correlation.
