2 Module rml/individual

This module implements a single type, individual , that is simply a constrained hash. The hash is constrained to have keys that are all strings, and should have the same keys as the union of feature and classifier names from the data set it will be used with. This module also provides a generator to return individuals for all rows in a partition.

Examples:

> (require rml/individual)
> (define iris
    (make-individual
     "sepal-length" 6.3
     "sepal-width" 2.5
     "petal-length" 4.9
     "petal-width" 1.5
     "classification" "Iris-versicolor"))
> (displayln (individual? iris))
#t
> (displayln (hash-keys iris))
(sepal-width sepal-length classification petal-width petal-length)

This code block shows the creation of a simple individual matching the Iris data set.

2.1 Types and Predicates

predicate
(individual? a) → boolean?
a : any/c

Returns #t if the value a is an individual.

2.2 Construction

constructor
(make-individual key
val ...
...
#:data-set data-set?) → individual?
  key : any/c
  val : any/c
  data-set? : #f

Creates an immutable individual in much the same way as the standard hash procedure, taking an even number of parameters assumed to be a repeating pair of key value. In this case however all keys will be checked to ensure they are strings.

If specified, the value for the keyword parameter #:data-set will be used to validate the names of the individual against the names of features and classifiers in the corresponding data set.

constructor
(data-set-individual dataset) → individual?
dataset : data-set?

Creates a mutable individual by taking all the names from the features and classifiers from dataset. All values are initialized to #f.

Examples:

> (define blank-iris (data-set-individual dataset))
> (displayln (individual? blank-iris))
#t
> (displayln (hash-keys blank-iris))
(classification sepal-width sepal-length petal-length petal-width)

2.3 Partition Generator

value
no-more-individuals : symbol?

A symbol that acts as the stop-value for individuals.

generator
(individuals dataset partition-id) → generator?
dataset : data-set?
partition-id : exact-nonnegative-integer?

This procedure implements a generator and returns each row of a partition as an individual.

Example:

> (for ([row (in-producer (individuals dataset 0) no-more-individuals)])
(displayln row))
