+
</pre>
<li>Because model training and testing is rather resource-intensive, we recommend to get started by using the example SLURM scripts, as explained below.</li>
 
</ul>
 
 
 
 
 
== Example scripts ==
 
 
 
The directory <code>/proj/nlpl/data/translation/hnmt_examples</code> contains a set of SLURM scripts for training and testing a baseline English-to-Finnish HNMT system. Copy the scripts to your own working directory before trying them out.
 
 
 
<ol>
 
<li><b>Data preparation:</b> The first script to launch is <code>prepare.sh</code>. It fetches the training, development and test data, extracts and reformats it, and calls the <code>make_encode.py</code> script to create vocabulary files for the source and target languages. This script runs rather fast and can be executed directly on a (Taito-GPU) login shell.</li>
 
<li><b>Training:</b> The second script is <code>train.sh</code> and calls <code>hnmt.py</code> to train a model. Launch it with <code>sbatch train.sh</code>. The parameters are fairly standard, except training time, which is kept low for testing purposes here (we tend to max out the Taito limits with 71h of training time...).
 
<ul>
 
<li>The <code>training.*.out</code> file contains information about the training batches (training time and loss), and also shows translations of a small number of held-out sentences for examining the training process:<br />
 
<pre>SOURCE / TARGET / OUTPUT
 
at least for the time being , all of them will continue working at their current sites .
 
ainakin toistaiseksi he kaikki jatkavat töitään nykyisissä toimipaikoissaan .
 
ainakin kaikki ne tekevät työtä tällä hetkellä .</pre>
 
 
</li>
 
</li>
<li> The <code>training.log</code> and <code>training.log.eval</code> files report additional information, as explained on [https://github.com/robertostling/hnmt#log-files].</li>
+
<li>You can also load CWB, Uplug and Udpipe modules:
<li> The training process creates a <code>train.model.final</code> file, which is then used for testing.</li>
+
<pre>module load nlpl-cwb</pre>
</ul></li>
+
<pre>module nlpl-uplug</pre>
<li><b>Testing:</b> The last script is <code>test.sh</code> and calls <code>hnmt.py</code> to test the previously created model on held-out data. Launch it with <code>sbatch test.sh</code>. HNMT includes evaluation scripts for chrF and BLEU and will report these scores if a reference file is given.
+
<pre>module load nlpl-udpipe</pre>
<ul>
 
<li>The resulting translations are written to <code>test.trans</code>.</li>
 
<li>In the <code>test.*.out</code> file, you should obtain scores close to the following (depending on the neural network initialization and the GPU used, results may vary slightly):
 
<pre>BLEU = 0.057750 (0.303002, 0.086025, 0.032001, 0.013334, BP = 1.000000)
 
LC BLEU = 0.057913 (0.303527, 0.086283, 0.032093, 0.013383, BP = 1.000000)
 
chrF = 0.310397 (precision = 0.355720, recall = 0.306064)</pre>

Models

See this page for details.

Using the Moses module

  • Activate the NLPL module repository:
    module use -a /projappl/nlpl/software/modules/etc         # Puhti
    module use -a /cluster/shared/nlpl/software/modules/etc   # Saga
  • Load the most recent version of the Moses module:
    module load nlpl-moses
  • Start using Moses, e.g. using the tutorial at http://statmt.org/moses/
  • The module contains the standard installation as described at http://www.statmt.org/moses/?n=Development.GetStarted:
    • cmph, xmlprc
    • with-mm
    • max-kenlm-order 10
    • max-factors 7
    • SALM + filter-pt
  • For word alignment, you can use GIZA++, Mgiza and fast_align. (The word alignment tools efmaral and eflomal are part of a separate module.)

Using the Efmaral module

  • Activate the NLPL module repository:
    module use -a /projappl/nlpl/software/modules/etc         # Puhti
    module use -a /cluster/shared/nlpl/software/modules/etc   # Saga
  • Load the most recent version of the Efmaral module:
    module load nlpl-efmaral
    
  • You can use the align.py script directly:
    align.py ...
  • You can use the efmaral module inside a Python3 script:
    python3

    python3 scripts/evaluate.py efmaral \
        3rdparty/data/test.eng.hin.wa \
        3rdparty/data/test.eng 3rdparty/data/test.hin \
        3rdparty/data/trial.eng 3rdparty/data/trial.hin

  • Activate the NLPL module repository:
    module use -a /projappl/nlpl/software/modules/etc         # Puhti
    module use -a /cluster/shared/nlpl/software/modules/etc   # Saga
  • Load the OPUS tools module:
    module load nlpl-opus
