Greedy Algorithm: A Beginner's Guide

SOLVED: Stochastic gradient descent (SGD) is simple but widely applicable optimization technique: For " exampl we can use it to train Support Vector Machine: The objective function in this case is given by:J (0)[4 Lossh (y()9 . 26)) Zu01? where Lossh (2) = max0,1 2 is the hinge loss function, (z() with for =1, n are the training examples; with y() e1,-1 being the label for the vector z(i)For simplicity; we ignore the offset parameter B0 in all problems on this page: The stochastic gradient upda

SOLVED: Assume that Jones Co. will need to purchase 100,000 Singapore dollars (SGD) in 180 days. Today's spot rate of the SGD is 0.50, and the 180-day forward rate is0.53. A call option on SGD exists, with an exercise price of 0.52, premium of0.02, and 180-day expiration date. A put option on SGD exists, with an exercise price of 0.51, premium of0.02, and a 180-day expiration date. Jones has developed the following probability distribution for the spot rate in 180 days:Possible Spot Rate in 180
