This is the documentation for the Project Prolog MLpack Library.

Here you can find documentaion on the used Datatypes, a detailed documentation for the available Methods and for the helper files.

Quickstart

Data Types

To connect mlpack and SICStus prolog i used the c interface of SICStus which can convert prolog datatypes to c datatypes and vise versa.

Here you can find a list of the available conversion types.

Extra Symbols

  • '+' is the symbol for inupting a concret value from prolog to c/c++

  • '-' is the symbol for inputing a variable from prolog to c/c++ that then gets assigned a value in one c side, that then can be used on the prolog side.

  • '[-]'

    is the symbol for an output value from c/c++ to prolog, in its function very similar to -.

Data Types

  • integer

    are the normal numbers 1,2,3...

    c/c++ : SP_integer

  • float

    are the numbers like 0.0, 1.2, 5.7...

    full definition prolog : float_32 shortend to float32 since this has the correct Byte size for its counter part double

    c/c++ : double

  • string

    are just atoms like: word, hello, nice7...

    c/c++ : char const *

  • integer(bool)

    there are no bool atoms in Prolog that could translate to bool in c, so i chose integer numbers as replacement with 1 = true and 0(or any other int number) = false

    c/c++ : SP_integer (1)true, (0)false

  • matrix

    is defined a just a long list/vector where you specify its row numbers

    currently on the prolog side you have to convert a normal list like [1, 2, 3] to a float_array with the help of some helper predicates in helper.pl.

    input :

    • prolog : +pointer(float_array) (converted list), +integer (list length), +integer (Rows)
    • c/c++ : float * array, SP_integer size, SP_integer rows

    output :

    • prolog : -pointer(float_array) (converted list), -integer (Columns), -integer (Rows)
    • c/c++ : float **array, SP_integer *colums, SP_integer *rows

  • vector

    currently on the prolog side you have to convert a normal list like [1, 2, 3] to a float_array with the help of some helper predicates in helper.pl.

    prolog : pointer(float_array) (converted list), integer (list length)

    c/c++ : float *array, SP_integer size
