popAggregate

<code>[ecr_logger]</code> ecr log object.

<code>[character]</code> names of attributes to extract, currently
"names", "fitness", "runtime", "fitness.holdout" and "fidelity" (if used) are supported.

extract

<code>[logical(1)]</code> whether to create a
<code>matrix</code>/<code>data.frame</code> for each generation (default).
Otherwise a list is returned for each generation containing
the value (if <code>length(extract) == 1</code>) or a named list of values.

simplify

<code>[logical(1)]</code> whether to return a <code>data.frame</code>
with rows for each individuum (if <code>TRUE</code>) or to return a <code>matrix</code>
with columns for each individuum compatible as fitness matrix
with various ecr tools (if <code>FALSE</code>, default). Only effective if
<code>simplify</code> is <code>TRUE</code>.

data.frame

Extract attributes saved for individuums in a
log object to a more accessible matrix or data.frame.

Performs simultaneous hyperparameter tuning and
feature selection through both single-objective and multi-objective
optimization as described in Binder, Moosbauer et al. (2019) <arXiv:1912.12912>.
Uses the 'ecr'-package as basis but adds mixed integer
evolutionary strategies and multi-fidelity functionality as well as operators
specific for the problem of feature selection.
