Python module for simulating gossip learning and decentralized federated learning.

The documentation is available at https://makgyver.github.io/gossipy/

gossipy is available as a PyPI module and it can be installed using pip:

$ pip install gossipy-dfl

• Models cache[Ormandi 2013] [Giaretta 2019] (partially implemented)
• Perfect matching [Ormandi 2013]
• More realistic online behaviour (currently it is a worst case scenario)
• DFL [Liu 2022]
• Segmented GL [Hu 2019]
• CMFL [Che 2021]
• MATCHA [Wang 2019]
• Add training stopping criterion
• GPU support (quick fix)

• Add 'Weights and Biases' support
