LASIN

Code and data for AAAI17 paper Combining Logical Abduction and Statistical INduction.

Usage

Prequesities

• mlpack
• swi-prolog
• pkg-config

Compile

Make sure pkg-config can load mlpack and swipl headers and libraries.

• If you have compiled swipl-devel from scratch and installed it in /usr/local, then you should use following command to add it to PKG_CONFIG_PATH:

  export PKG_CONFIG_PATH=/usr/local/share/pkgconfig:$PKG_CONFIG_PATH

• The mlpack library is usually installed in /usr/local, but its package config file is usually located in lib64/pkgconfig:

  export PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig:$PKG_CONFIG_PATH

Then you can test the installation by:

pkg-config --cflags mlpack
pkg-config --cflags swipl

If they output the library paths correctly, you can enter the src/core directory and make the C external predicates for SWI-Prolog:

cd src/core
make -j$nproc

Running

First add the library paths of mlpack and swipl to your LD_LIBRARY_PATH:

export LD_LIBRARY_PATH=/usr/local/lib/swipl/lib/x86_64-linux:/usr/local/lib64:$LD_LIBRARY_PATH

Extract the dataset:

tar -xvf data.tar.bz2

Then call the testing prolog scripts in src/prolog directory to run the experiments:

cd src/prolog
swipl test.pl

Now please call the learning predicates to run LASIN, e.g.:

-? test_go_M(10, Model, [200, 0.4, 0, 100], stroke).

More parameter settings and examples are listed in learn_dict.pl and learn_dict_new.pl.

Remark

We are optimising and tidying up the code, instructions about configuration and parameter settings will be added to this README file after the cleanup. Sorry about the inconvenience!
