Table II.

Ranking of Features Based on Using LASSO for Feature Selection. The 14 Features Are Ranked for Each Patient and the Table Lists Them According to the Mean Rank Across the 8 STNs (the Higher a Feature Is in the Table, the More Important it Is).

  Feature       Mean (± σ)        Median (25-75 percentiles)
56-95 Hz 5.8 (± 6.2) 3.5 (1.0 – 9.5)
21-30 Hz 5.8 (± 3.8) 4.5 (3.0 – 8.0)
350-500 Hz 5.9 (± 3.0) 6.0 (3.5 – 7.5)
301-349 Hz 7.1 (± 6.3) 5.5 (1.5 – 12.5)
5-7 Hz 7.1 (± 2.5) 6.5 (6.0 – 9.0)
Mobility 7.5 (± 6.0) 5.5 (3.0 – 12.0)
201-300 Hz 8.6 (± 6.2) 6.5 (4.0 – 14.0)
13-20 Hz 9.3 (± 6.1) 10.0 (3.0 – 14.5)
31-45 Hz 9.4 (± 5.3) 8.0 (4.5 – 15.0)
Mean LFP 9.5 (± 6.5) 12.0 (2.5 – 14.0)
Activity 9.6 (± 4.8) 8.5 (7.0 – 13.5)
Complexity 10.0 (± 3.6) 10.5 (7.0 – 12.5)
8-12 Hz 10.8 (± 4.6) 11.0 (7.5 – 15.0)
106-200 Hz 11.4 (± 6.0) 13.0 (7.0 – 16.0)
