SplineSplat: 3D Ray Tracing for Higher-Quality Tomography

A recent study published on arXiv investigates the use of neural networks for biometric authentication through finger-drawn digits on touchscreen devices. The research involved twenty participants who contributed a total of 2,000 finger-drawn digits. Two CNN architectures were evaluated, achieving approximately 89% authentication accuracy, while autoencoder approaches reached about 75% accuracy. The findings suggest that this method offers a secure and user-friendly biometric solution that can be integrated with existing authentication systems.

The article discusses a novel bi-level contextual bandit framework aimed at individualized resource allocation in high-stakes domains such as education, employment, and healthcare. This framework addresses the challenges of delayed feedback, hidden heterogeneity, and ethical constraints, which are often overlooked in traditional learning-based allocation methods. The proposed model optimizes budget allocations at the subgroup level while identifying responsive individuals using a neural network trained on observational data.
