The Classification of Valid and Invalid Beats of Three-Dimensional Nystagmus Eye Movement Signals Using Machine Learning Methods

Figure 5

Separation power values given by the Scatter method. The higher the value of a variable, the better the classification. Variables (1)–(19) are in the same order as in Tables 1–3: 𝑠𝑝𝑎_ℎ, 𝑠𝑝𝑎_𝑣, 𝑠𝑝𝑎_𝑡, 𝑠𝑝𝑑_ℎ, 𝑠𝑝𝑣_ℎ, 𝑠𝑝𝑣_𝑣, 𝑠𝑝𝑣_𝑡, 𝑓𝑝𝑎_ℎ, 𝑓𝑝𝑎_𝑣, 𝑓𝑝𝑎_𝑡, 𝑓𝑝𝑑_ℎ, 𝑓𝑝𝑣_ℎ, 𝑓𝑝𝑣_𝑣, 𝑓𝑝𝑣_𝑡, 𝑠𝑝𝑐_ℎ, 𝑠𝑝𝑐_𝑣, 𝑠𝑝𝑐_𝑡, 𝑓𝑝𝑚𝑣_ℎ, and 𝑞_𝑡.
