  (1)________________(a. underfitting / b. overfitting; 5 points) means a machine learning model is trained with the training dataset and performs well with the training dataset. However, the trained model does not perform well for new data (out-of-sample prediction; generalization). During the training step in the split test, we find out the optimal hyperparameters. If we select the optimal hyperparameter during the training step, the optimal hyperparameter should be selected at (2)_____________(a. Area A, b. Area B (dash line), Area C; 5 points) in the above figure. * Note: In the figure the generalization loss is the validation set loss.

As the external validity of a research investigation increases, its internal validity tends to decrease.

Which one is not true about the ensemble models?

In the Time Warner case, if Time were to increase its bid for Warner to offer a 20% premium (over the pre announcement price) and keep the proposed stock for stock structure, the exchange ratio would be:

One advantage of an LLC structure is that it avoids the double taxation in an acquisition to the selling shareholders. So would a stock sale of an LLC result in the same net tax to the shareholders as an asset sale? Why or Why not?

In our correlation analysis of the Producer Price Index (PPI) and Oil prices, we calculated our regression function to be: Y = 0.1177x + 1.4541, where Y = the % Change in PPI and X = % Change in Oil Prices.  If oil prices increased 20%, what by what precent would you forecast the PPI to change? Enter your answer rounded to the nearest hundredth with no % symbol, e.g. 6.837%  = 6.84 

Translate the following C/C++ code into MIPS assembly. Each C/C++ statement must be translated into MIPS assembly instructions without any optimization. If assembly level optimization is applied, substantial points will be deducted.  int arrays[10] = {1, 2, 3, 4, 5, 6, 7, 8. 9, 10}; int sum(int length) {     int i, sum;     sum = 0;     I = 0;     L0: }
