A.

A random subset of features that are chosen at each split in the decision tree

B.

Filtration of data that does not meet a pre-defined weighting thrsehold

C.

The creation of out-of-bag (OOB) data that is used to select features

D.

Closeness

C.

Betweenness

Options:

A.

The node is adjacent to a few nodes, each of each has high Page Ranks.

B.

The node has the only edge connecting its community to the rest of the graph.

C.

The node can be easily bypassed by communications taking other shorter paths.

D.

Questions # 15:

You conduct a TFIDF analysis on 3 documents containing raw text and derive TFIDF ("data", document y) = 1.908. You know that the term "data” only appears in document 2.

What is the TF of “data" in document 2?

Options:

A.

2 based on the following reasoning:

TFIDF = TF1DF = 1 908

You then know that IDF will equal LOG (32)=0.954

Therefore, TFIDF=TF*0.954 = 1.908

TF will then round to 2

B.

4 based on the following reasoning:

TFIDF = TF1DF = 1.908

You then know that IDF will equal LOG (3/1 )=0.477

Therefore, TFIDF=TF'0 477 = 1.908

TF will then round to 4

C.

6 based on the following reasoning:

TFIDF = TF1DF = 1.908

You then know that IDF will equal 3/1=3

Therefore, TFIDF=TF/3 = 1.908

TF will then round to 6

D.

11 based on the following reasoning:

TFIDF = TF1DF = 1908

You then know that IDF will equal LOG(3/2)=0.176

Therefore, TFIDF=TF"0.176 = 1.908

TF will then round to 11

Questions # 16:

What is an effective use of color in visualization?

Options:

A.
