On the Limitations of Fractal Dimension as a Measure of Generalization Charlie B. Tan University of Oxford Inรฉs Garcรญa-Redondo Imperial College London Qiquan Wang

Neural Information Processing Systems

Bounding and predicting the generalization gap of overparameterized neural networks remains a central open problem in theoretical machine learning. There is a recent and growing body of literature that proposes the framework of fractals to model optimization trajectories of neural networks, motivating generalization bounds and measures based on the fractal dimension of the trajectory. Notably, the persistent homology dimension has been proposed to correlate with the generalization gap.



ETO: Efficient Transformer-based Local Feature Matching by Organizing Multiple Homography Hypotheses

Neural Information Processing Systems

During the coarse matching phase, we organize multiple homography hypotheses to approximate continuous matches. Each hypothesis encompasses several features to be matched, significantly reducing the number of features that require enhancement via transformers.



Infusing Synthetic Data with Real-World Patterns for Zero-Shot Material State Segmentation

Neural Information Processing Systems

Minerals in rocks, sediment in soil, dust on surfaces, infection on leaves, stains on fabrics, and foam in liquids are some of these almost infinite numbers of states and patterns.
