Avoiding spurious minima by unlearning
	• Hopfield, Feinstein and Palmer suggested the following strategy: – Let the net settle from a random initial state and then do unlearning. – This will get rid of deep , spurious minima and increase memory capacity. • Crick and Mitchison proposed unlearning as a model of what dreams are for. – That’s why you don’t remember them (Unless you wake up during the dream) • But how much unlearning should we do? – And can we analyze what unlearning achieves?
