Question 3
What is the term for a set of vectors, with one vector for each word in the vocabulary?

1 point

  • Space
  • Array
  • Codebook

4.
Question 4
What is natural language processing?

1 point

  • Making natural text conform to formal language standards.
  • Translating natural text characters to unicode representations.
  • Translating human-readable code to machine-readable instructions.
  • Taking natural text and making inferences and predictions.

5.
Question 5
What is the goal of learning word vectors?

1 point

  • Find the hidden or latent features in a text.
  • Labelling a text corpus, so a human doesn’t have to do it.
  • Determine the vocabulary in the codebook.
  • Given a word, predict which words are in its vicinity.

6.
Question 6
What function is the generalization of the logistic function to multiple dimensions?

1 point

  • Hyperbolic tangent function
  • Exponential log likelihood

7.
Question 7
What is the continuous bag of words (CBOW) approach?

1 point

  • Vectors for the neighborhood of words are averaged and used to predict word n.
  • Word n is used to predict the words in the neighborhood of word n.
  • Word n is learned from a large corpus of words, which a human has labeled.
  • The code for word n is fed through a CNN and categorized with a softmax.

8.
Question 8
What is the Skip-Gram approach?

1 point

  • Word n is used to predict the words in the neighborhood of word n.
  • The code for word n is fed through a CNN and categorized with a softmax.
  • Word n is learned from a large corpus of words, which a human has labeled.
  • Vectors for the neighborhood of words are averaged and used to predict word n.

9.
