Present Tuesday: Austin, Gordon, Brieanna, Jaimie

• Working on debugging code/large RMSE values
  • Values looking more reasonable!
  • Problem was the reorientation of the matrix
    • Need to specify “F” form for reshaping
    • https://docs.scipy.org/doc/numpy/reference/generated/numpy.reshape.html

• Confusion with notation!
• Check it: Matrix and Array Notation:
• np.matrix
  • (row, col)
  • indexing
• np.array:
  • (row, col)
  • indexing
  • reshape array X w/ X.shape function
    • i.e. X.shape = (row, col)
  • reshape array X w/ np.reshape(X, (row,col))
    • np.reshape(X, (row, col))
