keras

keras, shows how to use keras to create a classifier for movie reviews. We will be interested in working on the GPU nodes at the Pittsburgh Supercomputing Center, but these calculations can also be done on your laptop, if you install keras there.

The notes:

• keras.pdf
• keras.tex

Python scripts:

• imdb.py, a keras/python script which carries out the IMDB analysis.
• imdb_decode.py, a keras/python script which decodes one of the movie reviews in the IMDB database.
• imdb_psc.py, a keras/python script which carries out the IMDB analysis, slightly modified so as to run on the PSC Bridges system, where the data can only be loaded from a local directory.

Shell scripts:

• imdb.sh, a bash script which runs imdb.py.
• imdb_copy.sh, a bash script which will copy the imdb dataset information from my PSC account to yours. You need to run this script once before trying the imdb example. Get the script by "cp ~jburkard/imdb_copy.sh imdb_copy.sh". Run the script by "bash imdb_copy.sh".
• imdb_psc.sh, a bash script, for use with SLURM on the PSC, which runs imdb_psc.py.

Text:

• imdb.txt, the output from imdb.py.
• imdb_decode.txt, the output from imdb_decode.py.
• imdb_psc.txt, the output from imdb_psc.py, as run on the PSC Bridges system.
