Helion

Helion is a data-driven framework that models the regularities of user-driven home automation, generates natural home automation scenarios, and provides stakeholders with tools to use the scenarios and obtain actionable outcomes.

Getting Started

To make it easier to run, respective library files are included in the project itself.

Quick Setup:

1. Add proper directories to your path:

Execute the Following commands or add them to your .bash_profile to set up your $PATH. Be sure to replace the paths with local paths on your machine

export PYTHONPATH=$PYTHONPATH:/Path/to/helion/libs/Daemon/python-daemon-2.2.0/
export PYTHONPATH=$PYTHONPATH:/Path/to/helion/libs/Daemon/python-daemon-2.2.0/daemon/ 
export PATH=$PATH:/Path/to/helion/libs/mitlm-master/
export PATH=$PATH:/Path/to/helion/libs/kramer-master/

2. Follow the instruction for respective scripts file.

Alternative Method:

If the quick setup method does not work, please install the latest version of libraries.

1. Download necessary files:

• MITLM - MIT Language Modeling Toolkit
• Python Daemon 1.5.5 - Library to implement a well-behaved Unix daemon process.
• Brain Files - The language model server script which reads/writes JSON documents to named pipes.

2. Untar MITLM and Python Daemon:

Execute the following command to un-tar the the MITLM and python daemon packages:

$ tar-xzf <package_name.tar.gz>

3. Add proper directories to your path:

Execute the Following commands or add them to your .bash_profile to set up your $PATH. Be sure to replace the paths with local paths on your machine

export PYTHONPATH=$PYTHONPATH:/Path/to/Python/Daemon/python-daemon-1.5.5/
export PYTHONPATH=$PYTHONPATH:/Path/to/Python/Daemon/python-daemon-1.5.5/daemon/ 
export PYTHONPATH=$PYTHONPATH:/Path/to/Python/Daemon/python-daemon-1.5.5/daemon/version/ 
export PATH=$PATH:/Path/to/MITLM/mitlm-0.4.1/ 
export PATH=$PATH:/Path/to/Brain/Files/

4. Build MITLM:

Navigate to the mitlm-0.4.1/ directory and execute the following commands:

$ ./configure
$ make

After both of these commands have been executed, you should be able to see the estimate-ngram, evaluate-ngram, and interpolate-ngram executables in the mitlm-0.4.1/ directory.

5. Instantiate the Brain:

Navigate to the folder where your training and vocabulary files are located. Then instantiate the brain by running:

$ braind data/helion.train data/helion.vocab

For more detailed instructions on how to interact and instantiate the Brain, see the README.
