AlphaSensAnalysis function

Sensitivity alpha-curve associated to MLP function

Obtain sensitivity alpha-curves associated to MLP function obtained from the sensitivities returned by SensAnalysisMLP.

AlphaSensAnalysis(
  sens,
  tol = NULL,
  max_alpha = 15,
  curve_equal_origin = FALSE,
  inp_var = NULL,
  line_width = 1,
  title = "Alpha curve of Lp norm values",
  alpha_bar = 1,
  kind = "line"
)

Arguments

• sens: sensitivity object returned by SensAnalysisMLP
• tol: difference between M_alpha and maximum sensitivity of the sensitivity of each input variable
• max_alpha: maximum alpha value to analyze
• curve_equal_origin: make all the curves begin at (1,0)
• inp_var: character indicating which input variable to show in density plot. Only useful when choosing plot_type='raw' to show the density plot of one input variable. If NULL, all variables are plotted in density plot. By default is NULL.
• line_width: int width of the line in the plot.
• title: char title of the alpha-curves plot
• alpha_bar: int alpha value to show as column plot.
• kind: char select the type of plot: "line" or "bar"

Returns

alpha-curves of the MLP function

Examples

mod <- RSNNS::mlp(simdata[, c("X1", "X2", "X3")], simdata[, "Y"],
                 maxit = 1000, size = 15, linOut = TRUE)

sens <- SensAnalysisMLP(mod, trData = simdata,
                        output_name = "Y", plot = FALSE)
