The paper constructs invariants by encoding local crossing events as elements of a noncommutative fundamental-group-like word system and aggregating signed differences in the group algebra. The transferable asset is not knotoid topology itself, but a representation that preserves ordered path history, distinguishes words such as xy and yx, and cancels pairs of locally redundant events. This suggests a path or event-stream neural module that pools reduced noncommutative words rather than ordinary commutative counts, with an auxiliary consistency loss enforcing invariance to selected local rewrite operations.
Replace ordinary bag-of-events pooling for an ordered trajectory, graph walk, or token event stream with a reduced-word representation in a free group. Each event contributes a signed group word, and the model aggregates signed differences (w-1), preserving order-sensitive information while making explicitly paired local events cancel.
