3. Assume a 2D plot of loss function is like a 'saw' (or sequence of Ws) "wwww" with the second valley is deeper than the rest (other valleys are of same depth) and the second hill (center hill of the first W) is marginally higher than other hills (other hills are of same height). To reach the global minima, what should be the appropriate beta value in Momentum with GD, assuming the current location is at the leftmost hill? Justify your answer. No marks without justification. Note: All other hyperparameters are constant. a. beta < 1 b. beta = 1 c. beta > 1 d. None of the above

This is to be done in MATLAB. Thanks! MISSION: Build a script (use the Live Script in MATLAB) that produces the derivative of the function f(x)=exp(−x)cos(x) between x=−5 and x=5 by applying both, the Forward Difference and Centered Difference approximations. Compare the numerically-determined derivatives with the actual derivative (product rule) by plotting all three curves on the same graph. Demonstrate graphically that the accuracy of the numerical derivative increases as the interval Δx decreases. It would be most effective to plot all three curves on the same graph for a given value of Δx. End up with a separate graph, demonstrating the comparison of all three curves, for each value of Δx chosen. Also, describe the "numerical approach," i.e. the method used to approximate the derivative. Thus, a clear description of the numerical approach at the beginning of the Live Script, and a detailed demonstration of how accuracy increases by systematically lowering Δx is expected as part of…

In Figure, suppose that the wellheads can be divided into two groups depending on gas pressure: a high-pressure group that includes wells 2, 3, 4, and 6 and a low-pressure group that includes wells 5, 7, 8, and 9 . Because of pressure difference, it is not possible to link the wellheads from the two groups. At the same time, both groups must be connected to the delivery point through wellhead 1. Determine the minimum pipeline network for this situation. Choices: a.) Set length of arcs 3-5, 5-3, 4-5, 5-4, 4-7, 7-4, 5-6, and 6-5 to ∞ : Total length = 53 b.)
