Questions and Answers

What is a key aspect to consider when applying clustering techniques in the context of airline route choice?

  • Choosing the clustering algorithm randomly
  • Using a high number of clusters
  • Defining a metric of similarity between data (correct)
  • Applying visual analytics after clustering

    • In the study by Evans and Lee, what method was used to identify route candidates?

  • Multinomial logistic regression
  • K-means clustering
  • Visual analytics
  • Hierarchical clustering on historical data (correct)

    • What are the potential problems if a wrong metric for clustering is chosen in the context of airline route choice?

  • The operation produces results that have no meaning (correct)
  • The clusters become more accurate
  • The classification accuracy increases
  • The visualization of data becomes clearer

    • What technique was proposed to forecast airline route choice through a combination of machine learning and visual analytics?
