Tools to validate Higgs-ML challenge submissions.

Layout of a zip submission file

zip submission files MUST have the following structure:

Archive:  ./my-team.zip
 extracting: my-team/LICENSE
 extracting: my-team/README
 extracting: my-team/higgsml-build
 extracting: my-team/higgsml-run
 extracting: my-team/higgsml-train
 extracting: my-team/extra/stuff

ie: created from:

my-team
|-- LICENSE
|-- README
|-- higgsml-build    (optional)
|-- higgsml-run
|-- higgsml-train
`-- extra            (optional)
    `-- stuff        (optional)

where:

  • higgsml-build (with that exact spelling) is the executable script (or binary) which builds the code from sources (OPTIONAL)
  • higgsml-run (with that exact spelling) is the executable script (or binary) which runs the prediction
  • higgsml-train (with that exact spelling) is the executable script (or binary) which runs the training
  • LICENSE (or LICENSE.txt) contains an OSI-approved license
  • README (or README.md or README.txt) contains some documentation about the code.

(on Windows (TM), the scripts should be called higgsml-build.bat, higgsml-run.bat and higgsml-train.bat)

In case you submit 2 codes, each code should have its own directory structure. e.g.:

Archive:  ./my-team.zip
 extracting: my-team/code-1/LICENSE
 extracting: my-team/code-1/README
 extracting: my-team/code-1/higgsml-run
 extracting: my-team/code-1/higgsml-train

 extracting: my-team/code-2/LICENSE
 extracting: my-team/code-2/README
 extracting: my-team/code-2/higgsml-run
 extracting: my-team/code-2/higgsml-train

i.e.: created from:

my-team
|-- code-1
|   |-- LICENSE
|   |-- README
|   |-- higgsml-run
|   `-- higgsml-train
`-- code-2
    |-- LICENSE
    |-- README
    |-- higgsml-run
    `-- higgsml-train

Environment configuration, if needed, should be performed in the higgsml-xyz scripts (e.g. setting up $PYTHONPATH or $LD_LIBRARY_PATH environment variables.)

If you ship the sources (and not just a binary) the directory MUST contain a file higgsml-build (or higgsml-build.bat on Windows (TM)) which can be called with no argument, and will run the build procedure in-place (i.e. not out of tree) so the higgsml-run and higgsml-train can find all the necessary assets at runtime. The higgsml-build script should not try to fetch additional sources from outside the code directory (i.e. no outbound connection allowed.)

zip file generation

A tool is available to generate a zip file according to the above rules: hml-mk-zip

  • First, install the (latest) Go toolchain from golang.org

  • Then, install hml-mk-zip from sources:

$ go get github.com/sbinet/hml/hml-mk-zip
$ hml-mk-zip my-team.zip my-team

deflating: my-team/code-1/LICENSE
deflating: my-team/code-1/README.md
deflating: my-team/code-1/go-higgsml
deflating: my-team/code-1/higgsml-run
deflating: my-team/code-1/higgsml-train
deflating: my-team/code-2/LICENSE
deflating: my-team/code-2/README.md
deflating: my-team/code-2/higgsml-run
deflating: my-team/code-2/higgsml-train
deflating: my-team/code-2/higgsml_simplest_v2.py

Example

github.com/sbinet/hml has a couple of testcases (with python and go programs). Let's try to make a proper zip file:

$ cd /somewhere
$ git clone git://github.com/sbinet/hml
$ cd hml/testdata
$ hml-mk-zip team-3.zip team-3
2014/09/12 09:33:22 deflating: team-3/LICENSE
2014/09/12 09:33:22 deflating: team-3/README.md
2014/09/12 09:33:22 deflating: team-3/higgsml-run
2014/09/12 09:33:22 deflating: team-3/higgsml-simplest.py
2014/09/12 09:33:22 deflating: team-3/higgsml-train

hml-validate

hml-validate is a tool to validate the content of a zip submission file, to make sure that zip file will be usable by HEP physicists.

hml-validate will run off a zip submission file.

If the zip submission file contains a higgsml-build script, it will be run prior to anything else, to generate the needed binaries and assets.

higgsml-build MUST be called with no argument.

hml-validate will then run (when instructed to do so by the -train switch from the command line):

$ higgsml-train training.csv trained.dat

to create a trained.dat file from the training.csv sample.

Finally, hml-validate will run:

$ higgsml-run test.csv trained.dat submission.csv

to create the submission.csv file from the test sample and the training parameters. This submission.csv file MUST be identical to the one you have submitted during the contest.

When everything is successful, it will collect the results (the submission.csv for each code) under a new higgsml-output directory.

If you have any question, feel free to ask on: https://www.kaggle.com/c/higgs-boson/forums

Install hml-validate

  • First, install the (latest) Go toolchain from golang.org

  • Then, install hml-validate from sources:

$ go get github.com/sbinet/hml/hml-validate

Run hml-validate

$ hml-validate my-team.zip
::: higgsml-validate...
Archive: my-team.zip
  inflating: my-team/README.md
  inflating: my-team/higgsml-run
  inflating: my-team/higgsml-train

::: run prediction...
::: higgs-ml [prediction]...
::: args: test.csv trained.dat submission.csv
::: compute the score for the test file entries [test.csv]
::: loop again on test file to load BDT score pairs
::: sort on the score
::: build a map key=id, value=rank
::: you can now submit [submission.csv] to Kaggle website
::: timing: 15.862965585s
::: bye.
::: higgs-ml [prediction]... [ok]
::: run prediction... [ok] (delta=15.903641153s)

hml-validate help

$ hml-validate -help
Usage: hml-validate zipfile-or-directory [test.csv [training.csv]]

where:
  - test.csv is a test file (taken from $PWD if not given.)
  - training.csv is a training file (taken from $PWD if not given.)
    training.csv is needed iff -train is enabled.

ex:
 $ hml-validate my-team
 $ hml-validate my-team/
 $ hml-validate my-team.zip
 $ hml-validate my-team.tar.gz
 $ hml-validate my-team /path/to/test.csv
 $ hml-validate my-team /path/to/test.csv /path/to/training.csv

options:
  -train=false: switch to run the training during validation
