Any blind source separation algorithm consists of a contrast or cost function plus an adaptation or learning rule which is used to minimize or maximize the cost function so as to perform separation. This typically used in human being brains to distinguish between the different voices and scenes. Here we introduce an approach that explains some strange natural phenomena and relate their occurrence to what is called bad learning in the process of blind source separation.enBlind Source SeparationCost functionslearning rulesArticle
