CLEP is a framework that contains novel methods for generating patient representations from any patient level data and its corresponding prior knowledge encoded in a knowledge graph. The framework is depicted in the graphic below

The code can be installed from PyPI with:

$ pip install clep

The most recent code can be installed from the source on GitHub with:

$ pip install git+https://github.com/hybrid-kg/clep.git

For developers, the repository can be cloned from GitHub and installed in editable mode with:

$ git clone https://github.com/hybrid-kg/clep.git
$ cd clep
$ pip install -e .

Read the official docs for more information.

Note: The data must be in a tab separated file format.

Note: The data must be in a tab separated file format.

The graph format CLEP can handle is a modified version of the Edge List Format. Which looks as follows:

Note: The data must be in a tab separated file format & if your knowledge graph does not have relations between the source and the target, just populate the relation column with "No Relation".

Note: These are very basic commands for clep, and the detailed options for each command can be found in the documentation

1. Radical Searching The following command finds the extreme samples with extreme feature values based on the control population.

$ clep sample-scoring radical-search --data <DATA_FILE> --design <DESIGN_FILE> --control Control --threshold 2.5 --control_based --ret_summary --out <OUTPUT_DIR>

2. Graph Generation The following command generates the patient-gene network based on the method chosen (Interaction_network).

$ clep embedding generate-network --data <SCORED_DATA_FILE> --method interaction_network --ret_summary --out <OUTPUT_DIR>

3. Knowledge Graph Embedding

The following command generates the embedding of the network passed to it.

$ clep embedding kge --data <NETWORK_FILE> --design <DESIGN_FILE> --model_config <MODEL_CONFIG.json> --train_size 0.8 --validation_size 0.1 --out <OUTPUT_DIR>

4. Classification

The following command carries out classification on the given data file for a chosen model (Elastic Net) using a chosen optimizer (Grid Search).

$ clep classify --data <EMBEDDING_FILE> --model elastic_net --optimizer grid_search --out <OUTPUT_DIR>
