Researchers have developed a new method to analyze neural network representations by defining an equivalence relation that creates a quotient space. This space, when intersected with an input manifold, can be split into components related to local rank and intersections. The study proves that the homology groups of neural representations are isomorphic to these quotient homology groups, allowing for intrinsic calculation of Betti numbers without external metrics. Experiments on toy datasets demonstrate that this overlap homology approach tracks topological features better than persistent homology, and its evolution during training is also examined. AI
