What people of the region were identified as the Sea People or the Purple People in the text, a Greek word which identifies this society’s production of purple and blue textiles?

The Sumerians produced this first epic poem

This group is considered to be the ancestors of modern humans:

Figure 1: Training Dataset for Car Ownership Instance Employed Insured Marital Status Car Ownership 1 Yes No Single Yes 2 Yes Yes Single No 3 No No Married Yes 4 No Yes Single Yes 5 Yes Yes Married No 6 No No Single No Review the table labeled Figure 1: Training Dataset for Car Ownership. Assume we want to use a decision tree to predict if a person owns a car or not. Using entropy as the measure of node impurity, what is the information gain if the split is done on the attribute of being employed?

Select all possible columns that can be set as class label for a predictive task.   Tid Refund marital Status Taxable Income Cheat 1 Yes Single 125k No 2 No Married 100k No 3 No Single 70k No 4 Yes Married 120k No 5 No Divorced 95k Yes 6 No Married 60k No 7 Yes Divorced 220k No 8 No Single 95k Yes 9 No Married 75k No 10 No Single 90k Yes  

Compute the simple matching and Jaccard coefficient between X and Y: X = (1, 0, 1, 0) Y = (1, 1, 0, 0)

You trained a model to predict home market prices. Your model performs well on your dataset, but performs poorly on a different dataset. How can you improve your model?

You are asked to train a model for detecting fraudulent bank transactions. The bank studies show that the bank sustains more damage when a fraudulent transaction is approved compared to when a normal transaction is blocked. For the bank to sustain less damage, which cost matrix should you use to tune your model? (F stands for Fraudulent, and N stands for Normal.)

You have a dataset of 100,000 dog images comprised of 100 different breeds. If you want to use a Support Vector Machine (SVM) for a classification task, which approach should you choose and why?

Assume we want to use a decision tree to predict a person’s pet type. Using misclassification error as the measure of node impurity, which attribute provides the best split?
