Optimize Weights (Backward)

Synopsis

Assumes that features are independent and optimizes the weights of the attributes with a linear search.

Description

Uses the backward selection idea for the weighting of features.

This is an example set output port

weights

performance

Parameters

keep best

Keep the best n individuals in each generation.

generations without improval

Stop after n generations without improvement of the performance.

weights

Use these weights for the creation of individuals in each generation.

normalize weights

Indicates if the final weights should be normalized.

use local random seed

Indicates if a local random seed should be used.

local random seed

Specifies the local random seed

user result individual selection

Determines if the user wants to select the final result individual from the last population.

show population plotter

Determines if the current population should be displayed in performance space.

plot generations

Update the population plotter in these generations.

constraint draw range

Determines if the draw range of the population plotter should be constrained between 0 and 1.

draw dominated points

Determines if only points which are not Pareto dominated should be painted.

population criteria data file

The path to the file in which the criteria data of the final population should be saved.

maximal fitness

The optimization will stop if the fitness reaches the defined maximum.
