ArchiveAsyncFSelectFrozen: Frozen Rush Data Storage

In mlr3fselect: Feature Selection for 'mlr3'

Frozen Rush Data Storage

Description

Freezes the Redis data base of an ArchiveAsyncFSelect to a data.table::data.table(). No further points can be added to the archive but the data can be accessed and analyzed. Useful when the Redis data base is not permanently available. Use the callback mlr3fselect.async_freeze_archive to freeze the archive after the optimization has finished.

S3 Methods

• as.data.table(archive)
  ArchiveAsyncFSelectFrozen -> data.table::data.table()
  Returns a tabular view of all performed function calls of the Objective.

Arguments

i

(integer(1))
The iteration value to filter for.

uhash

(logical(1))
The uhash value to filter for.

---

Method learners()

Retrieve list of trained mlr3::Learner objects of the i-th evaluation, by position or by unique hash uhash. i and uhash are mutually exclusive.

Usage

ArchiveAsyncFSelectFrozen$predictions(i = NULL, uhash = NULL)

Arguments

i

(integer(1))
The iteration value to filter for.

uhash

(logical(1))
The uhash value to filter for.

---

Method resample_result()

Retrieve mlr3::ResampleResult of the i-th evaluation, by position or by unique hash uhash. i and uhash are mutually exclusive.

Arguments

i

(integer(1))
The iteration value to filter for.

uhash

(logical(1))
The uhash value to filter for.

---

Method print()

Printer.

Usage

ArchiveAsyncFSelectFrozen$print()

Arguments
