1. What are Ensemble Algorithms? Write an algorithm for BOOSTING method.

1. Assume that two individuals offer to sell you their predictive models M1 and M2. The confusion matrices produced by each model are as follows. What is the accuracy of each model? Assuming that precision is of paramount importance in your application, which of the two models would you buy? Why?

Performance of M1				Performance of M2
	Predicted True	Predicted False			Predicted True	Predicted False
Actually True	5	95		Actually True	85	15
Actually False	10	90		Actually False	95	5
