Description Objects from the Class Slots Author(s) Examples
An S4 class
containing the trained maximum entropy model and its corresponding weights as a data.frame
with three columns: Weight
, Label
, and Feature
.
Objects could in principle be created by calls of the
form new("maxent", ...)
.
The preferred form is to have them created via a call to
maxent
.
model
Object of class "character"
:
stores the trained maximum entropy model as returned from maxent
weights
Object of class "data.frame"
:
contains the weights of the trained maximum entropy model, with three columns: Weight
, Label
, and Feature
.
