Besides, we adapted torchdiffeq in https://github.com/rtqichen/torchdiffeq into a local package due the change of its oringinal codes
Python files: mutualistic_dynamics.py
python mutualistic_dynamics.py --T 5 --network grid --dump --sampled_time irregular --baseline ndcn --viz --gpu -1 --weight_decay 1e-2
--network *** for underlining graph with choices=['grid', 'random', 'power_law', 'small_world', 'community']
--sampled_time ** for irregularlly-sampled graph dynamics or regularly sampled ones with choices=['irregular', 'equal']
--baseline ** chooses any model from choices=['ndcn', 'no_embed', 'no_control', 'no_graph', 'lstm_gnn', 'rnn_gnn', 'gru_gnn']
Please refer to the code for the detailed parameter choices
Python files: heat_dynamics.py and gene_dynamics.py
python heat_dynamics.py --T 5 --network grid --dump --sampled_time irregular --baseline ndcn --viz --gpu -1 --weight_decay 1e-3
python gene_dynamics.py --T 5 --network grid --dump --sampled_time irregular --baseline ndcn --viz --gpu -1 --weight_decay 1e-4
3 dynamics (gene, heat, mutualistic dynamics) on 5 graphs (grid', 'random', 'power_law', 'small_world', 'community' graphs) are shown in gif folder, or download our ppt https://drive.google.com/file/d/1KBl-6Oh7BRxcQNQrPeHuKPPI6lndDa5Y and show in full screen to check our compiled animations.
