Question

1. Match the following Machine Learning algorithms to their descriptions:

1. Linear Regression A. A system of assigning values by sorting data through a series of questions which can be represented in a flow chart.

2. Linear Discriminant Analysis B. A classifier which uses data points of known class to vote on which class a new point would belong in.

3. Decision Tree C. An algorithm that calculates a line to represent a set of data which is more or less correlated to it on a scale of -1 to 1.

4. Naive Bayes D. A linear classification algorithm for more than 2 classes

5. K-Nearest Neighbors E. A predictive model that calculates probability using Bayes Theorem.

2. In 2-3 sentences each, explain 2 reasons that a machine learning classifier could be bad despite a correctly-classified percentage above 70%.

3. If I roll two dice, what are the odds that both will be the same number? Note: You must show your work for full credit.

Answer #1

1. Linear Regression - C. An algorithm that calculates a line to represent a set of data which is more or less correlated to it on a scale of -1 to 1.

[Machine learning] Principal Component Analysis (PCA) and Linear
Discriminant Analysis (LDA)
In this problem two linear dimenionality reduction methods will
be discussed. They are principal component analysis (PCA) and
linear discriminant analysis (LDA).
In a supervised binary classification task we have a total of 15
features, among which only 4 are useful for predicting the target
variable, the other features are pure random noise with very high
variance. What complicates matters even worse is that the 4
features when considered...

1. In a multiple
regression model, the following coefficients were obtained:
b0 = -10 b1
= 4.5 b2 = -6.0
a. Write the
equation of the estimated multiple regression model. (3 pts)
b Suppose a
sample of 25 observations produces this result, SSE = 480. What is
the estimated standard error of the estimate? (5 pts)
2. Consider the
following estimated sample regression equation:
Y = 12 + 6X1 -- 3 X2
Determine which of the following
statements are true,...
