build_instance_feature: Flatten 'mild_df' data to the instance level

In mildsvm: Multiple-Instance Learning with Support Vector Machines

Flatten mild_df data to the instance level

Description

Flatten mild_df type of data to regular multiple instance data where each instance is a vector by extracting distribution sample quantiles, mean and sd.

Usage

build_instance_feature(
  data,
  qtls = seq(0.05, 0.95, length.out = 10),
  mean = TRUE,
  sd = TRUE
)

Arguments

data	A mild_df object.
qtls	Quantiles to be extracted from each instance empirical distribution.
mean	A logical for whether or not to extract mean.
sd	A logical for whether or not to extract standard deviation.

Value

A summarized data.frame at the instance level.
