/in Uncategorized /by developer1. Using the code presented in Section 8.6:
(a) Generate a dataset (X, y).
(b) Apply a PCA transformation on X, which we denote Ẋ.
(c) Compute MDI, MDA, and SFI feature importance on (Ẋ,y), where the base estimator is RF.
(d) Do the three methods agree on what features are important? Why?
2. From exercise, generate a new dataset (Ẍ,y), where Ẍ is a feature union of X and Ẋ .
(a) Compute MDI, MDA, and SFI feature importance on (Ẍ,y), where the base estimator is RF.
(b) Do the three methods agree on the important features? Why?

/in Uncategorized /by developer1 What Are Teams And How Are They Formed Consider This Question In The Context Of Yo 2765501
/in Uncategorized /by developer1. What are teams and how are they formed? Consider this question in the context of your
group and the board of your Central Bank.
2. How successful is your team in deriving their recommendation? Is your team able to agree
on and manage their schedule? Are their different opinions and how are they resolved?
3. Assume that you are the chairman of the central bank board and your team mates are board
members. How would you handle different opinions and would you do things differently
compared to what your team did?
4. Now assume that you are board member and have a different recommendation to other
board members. Having gone through this process, how might you contribute to the
discussion differently in the future?

1 What Are Diva S Projected Profits For The Fiscal Year Ending September 1995 2 What 2712964
/in Uncategorized /by developer1. What are Diva’s projected profits for the fiscal year ending September 1995?
2. What factors affect a firm’s exposure to exchange rate risk? How much exposure to exchange rate risk does Diva Shoes have in April 1995?
3. Suppose that Diva chooses to hedge its exposure in yen using the forward contract described in case Appendix A or the currency option described in case Appendix B. Assume that you lock in these contracts at the forward price implied by interest-rate parity for September 1995. Draw the payoffs to the position at maturity for each alternative with the exchange rate defined in USD/JPY × 10,000 units (i.e., the same units as the currency option is quoted). What do you see as the tradeoffs between the alternatives?
4. Do you think Bisno should remain strictly a shoe salesman or do you favor hedging his exposure? If you favor hedging, which alternative would you recommend to him?

1 We Wish To Extract Tones At 150 And 250 Hz From Tones At 1050 And 1150 Hz And Then 3798800
/in Uncategorized /by developer1. We wish to extract tones at 150 and 250 Hz from tones at 1050 and 1150 Hz and then downsample the output by the largest possible factor. Assume the signal containing the four tones is sampled at 40 kHz. Use a Kaiser window FIR filter with a passband from 0 to 300Hz (3 dB down at band edge) and attenuation > 80 dB at 500 Hz. Implement the filter, maximally downsample the output, and examine the output spectrum to ensure that it meets specifications. Now reimplement the filtering and downsampling with a single polyphase downsampling filter. Compare the number of operations required for the original FIR implementation and the polyphase implementation. (4 marks) 2. Upsample the output of the downsampling filter of Question 1 back to the original 40 kHz sampling rate by designing an appropriate upsampling filter using zero packing and low-pass filtering. Then reimplement as a polyphase upsampling filter. Check the output of the polyphase upsampler against the filtered zero-packed output to show they are the same. Compare the number of operations required for the original single-rate FIR implementation from Q1 and the polyphase downsampling/upsampling implementation in this question. (6 marks) 3. Without incurring additional computation, modify the polyphase upsampling filter to frequency shift the data by heterodyning with a 2.4 kHz carrier. That is the tones at 150, and 250 Hz will now be placed at 2150, 2250, 2550, and 2650 Hz. Document Preview:

1 We Are In Two Good Two Country Where All Of The Assumptions Of The Heckscher Ohlin 3298412
/in Uncategorized /by developer1) We are in two good, two country, where all of the assumptions of the Heckscher-Ohlin model of trade are satisfied. Suppose that in Japan there are 50 workers and 50 acres of land, while in the US there are 100 workers and 200 acres of land. Suppose furthermore that the two goods, rice, and cloth, are produced using land and labor. Rice is land intensive. Suppose the two countries open up to trade. What will be the pattern of trade? why?
