Quantum entanglement provides a competitive advantage in adversarial games

arXiv:2603.10289v1 Announce Type: cross Abstract: Whether uniquely quantum resources confer advantages in fully classical, competitive environments remains an open question. Competitive zero-sum reinforcement learning is particularly challenging, as success requires modelling dynamic interactions between opposing agents rather than static state-action…

Denoising the US Census: Succinct Block Hierarchical Regression

arXiv:2603.10099v1 Announce Type: new Abstract: The US Census Bureau Disclosure Avoidance System (DAS) balances confidentiality and utility requirements for the decennial US Census (Abowd et al., 2022). The DAS was used in the 2020 Census to produce demographic datasets critically…

Self-Scaled Broyden Family of Quasi-Newton Methods in JAX

arXiv:2603.10599v1 Announce Type: cross Abstract: We present a JAX implementation of the Self-Scaled Broyden family of quasi-Newton methods, fully compatible with JAX and building on the Optimistix~cite{rader_optimistix_2024} optimisation library. The implementation includes BFGS, DFP, Broyden and their Self-Scaled variants(SSBFGS, SSDFP,…

Hardware Efficient Approximate Convolution with Tunable Error Tolerance for CNNs

arXiv:2603.10100v1 Announce Type: new Abstract: Modern CNNs’ high computational demands hinder edge deployment, as traditional “hard” sparsity (skipping mathematical zeros) loses effectiveness in deep layers or with smooth activations like Tanh. We propose a “soft sparsity” paradigm using a hardware…
