MNIST - handwritten digits

This repository contains tests of the AlignmentRepa repository using data from the MNIST dataset. The AlignmentRepa repository is a fast Haskell implementation of some of the practicable inducers described in the paper The Theory and Practice of Induction by Alignment at https://greenlake.co.uk/.

Documentation

There is an analysis of this dataset here.

Installation

The NIST executables require the AlignmentRepa module which is in the AlignmentRepa repository. See the AlignmentRepa repository for installation instructions of the Haskell compiler and libraries.

Then download the zip files or use git to get the NIST repository and the underlying Alignment and AlignmentRepa repositories -

cd
git clone https://github.com/caiks/Alignment.git
git clone https://github.com/caiks/AlignmentRepa.git
git clone https://github.com/caiks/NIST.git

Then download the dataset files, for example -

cd NIST
wget http://yann.lecun.com/exdb/mnist/train-images-idx3-ubyte.gz
wget http://yann.lecun.com/exdb/mnist/train-labels-idx1-ubyte.gz
wget http://yann.lecun.com/exdb/mnist/t10k-images-idx3-ubyte.gz
wget http://yann.lecun.com/exdb/mnist/t10k-labels-idx1-ubyte.gz

Usage

The practicable model induction is described here.

NIST_engine3 Ubuntu 16.04 Intel(R) Xeon(R) Platinum 8175M CPU @ 2.50GHz using 1756 MB memory in 11505 seconds,

cd ../Alignment
rm *.o *.hi

cd ../AlignmentRepa
rm *.o *.hi

gcc -fPIC -c AlignmentForeign.c -o AlignmentForeign.o -O3

cd ../NIST
rm *.o *.hi

ghc -i../Alignment -i../AlignmentRepa ../AlignmentRepa/AlignmentForeign.o NIST_engine3.hs -o NIST_engine3.exe -rtsopts -O2

./NIST_engine3.exe +RTS -s >NIST_engine3.log 2>&1 &

tail -f NIST_engine3.log

To experiment with the dataset in the interpreter,

cd ../Alignment
rm *.o *.hi

cd ../AlignmentRepa
rm *.o *.hi

gcc -fPIC -c AlignmentForeign.c -o AlignmentForeign.o -O3

cd ../NIST

ghci -i../Alignment -i../AlignmentRepa ../AlignmentRepa/AlignmentForeign.o
:set -fobject-code
:l NISTDev

Then exit the interpreter,

rm NISTDev.o

ghci -i../Alignment -i../AlignmentRepa ../AlignmentRepa/AlignmentForeign.o
:l NISTDev
