How should this proposal bepresented to the company board of directors who understand and make it a policy to evaluate by discounted-cash-flow rate of return?

An oil company is offered a lease of a group of oil wells on which the primaryreserves are close to exhaustion. The major condition of the purchase is that the oilcompany must agree to undertake a water-flood project at the end of five years tomake possible secondary recovery. No immediate payment by the oil company is required. The relevant cash flows have been estimated as follows:

 Year 0 1-4 5 6-20 Discounted-cash-flow rate of return Net present worth at 10% 0 \$50 ,000 -\$650,000 \$100,000 ? \$227,000

Should the lease-and-flood arrangement be accepted? How should this proposal bepresented to the company board of directors who understand and make it a policy to evaluate by discounted-cash-flow rate of return?

Prove that the hypothesis class of all conjunctions over d variables is PAC learnable and bound its sample complexity.

1.  In this question, we study the hypothesis class of Boolean conjunctions defined as follows. The instance space is X ={0,1}d and the label set is Y ={0,1}. A literal over the variables x1, . . ., xd is a….

Show that for every probability distribution D, the Bayes optimal predictor fD is optimal, in the sense that for every classifier g from X to {0,1}, LD( fD) ≤ LD(g).

1. Let H be a hypothesis class of binary classifiers. Show that if H is agnostic PAC learnable, then His PAC learnable as well. Furthermore, if A is a successful agnostic PAC learner for H, then A is also a….

. Show that the algorithm just described satisfies the requirements for being a RP solver for ERMH.

1. On the basis of the preceding, prove that for any k ≥ 3, the ERMHnk problem is NP-hard. 2 In this exercise we show that hardness of solving the ERM problem is equivalent….
