Quantitative Bounds for Sorting-Based Permutation-Invariant Embeddings

Researchers have refined quantitative bounds for permutation-invariant embeddings used in graph deep learning, addressing gaps in previous work by improving upper and lower bounds for injectivity and providing estimates of bi-Lipschitz constants independent of input dimensions but dependent on the number of points. This advancement is crucial for developers working with graph neural networks to ensure consistent performance across varying permutations of node orders.
