Exercise

Second order link-based features

In this exercise, you will compute the number and ratio of churn and non-churn neighbors in the second order neighborhood. The procedure is the same as in the previous exercise, except now you use the second order adjacency matrix.

Instructions

100 XP
  • Compute the number of churn neighbors in the second order neighborhood using SecondOrderMatrix and the Churn attribute. Convert the result with as.vector() and add it as ChurnNeighbors2 to network.
  • Also compute NonChurnNeighbors2, the number of non-churn neighbors in the second order neighborhood.
  • Calculate RelationalNeighbor2, the ratio of churners in the second order neighborhood, by dividing ChurnNeighbors2 with the sum of ChurnNeighbors2 and NonChurnNeighbors2.
