Network Diffusion is a package for simulating spreading phenomena.

Network Diffusion - spreading models in networks

This Python library provides a versatile toolkit for simulating diffusion processes in complex networks. It offers support for various types of models, including temporal models, multilayer models, and combinations of both.

A Short Example

import network_diffusion as nd

# define the model with its internal parameters
spreading_model = nd.models.MICModel(
    seeding_budget=[90, 10, 0],  # 95% act suspected, 10% infected, 0% recovered
    seed_selector=nd.seeding.RandomSeedSelector(),  # pick infected act randomly
    protocol="OR",  # how to aggregate impulses from the network's layers
    probability=0.5,  # probability of infection
)

# get the graph - a medium for spreading
network = nd.mln.functions.get_toy_network_piotr()

# perform the simulation that lasts four epochs
simulator = nd.Simulator(model=spreading_model, network=network)
logs = simulator.perform_propagation(n_epochs=3)

# obtain detailed logs for each actor in the form of JSON
raw_logs_json = logs.get_detailed_logs()

# or obtain aggregated logs for each of the network's layer
aggregated_logs_json = logs.get_aggragated_logs()

# or just save a summary of the experiment with all the experiment's details
logs.report(visualisation=True, path="my_experiment")

Key Features

• Complex Network Simulation: The library enables users to simulate diffusion processes in complex networks with ease. Whether you are studying information spread, disease propagation, or any other diffusion phenomena, this library has you covered.

• Temporal Models: You can work with temporal models, allowing you to capture the dynamics of processes over time. These temporal models can be created using regular time windows or leverage CogSnet.

• Multilayer Networks: The library supports multilayer networks, which are essential for modelling real-world systems with interconnected layers of complexity.

• Predefined Models: You have the option to use predefined diffusion models such as the Linear Threshold Model, Independent Cascade Model, and more. These models simplify the simulation process, allowing you to focus on your specific research questions.

• Custom Models: Additionally, Network Diffusion allows you to define your own diffusion models using open interfaces, providing flexibility for researchers to tailor simulations to their unique requirements.

• Centrality Measures: The library provides a wide range of centrality measures specifically designed for multilayer networks. These measures can be valuable for selecting influential seed nodes in diffusion processes.

• NetworkX Compatible: Last but not least, the package is built on top of NetworkX, ensuring seamless compatibility with this popular Python library for network analysis. You can easily integrate it into your existing NetworkX-based workflows.

Package installation

To install the package, run this command: pip install network_diffusion. Please note that we currently support Linux, MacOS, and Windows, but the package is mostly tested and developed on Unix-based systems.

To contribute, please clone the repo, switch to a new feature branch, and install the environment:

conda env create -f requirements/environment.yml
conda activate network-diffusion
pip install -e .
