Convergence and efficiency proof of quantum imaginary time evolution for bounded order systems
arXiv:2506.03014v4 Announce Type: replace-cross Abstract: Many current and near-future applications of quantum computing utilise parametric families of quantum circuits and variational methods that can suffer from obstac…
On the Existence of Consistent Adversarial Attacks in High-Dimensional Linear Classification
arXiv:2506.12454v2 Announce Type: replace-cross Abstract: What fundamentally distinguishes an adversarial attack from a misclassification due to limited model expressivity or finite data? In this work, we investigate thi…
Quantum matrix arithmetics with Hamiltonian evolution
arXiv:2510.06316v3 Announce Type: replace-cross Abstract: The efficient implementation of matrix arithmetic operations underpins the speedups of many quantum algorithms. We develop a suite of methods to perform matrix ar…
Nonlinear Dynamics In Optimization Landscape of Shallow Neural Networks with Tunable Leaky ReLU
arXiv:2510.25060v2 Announce Type: replace-cross Abstract: In this work, we study the nonlinear dynamics of a shallow neural network trained with mean-squared loss and leaky ReLU activation. Under Gaussian inputs and equa…
The Alexander-Hirschowitz theorem for neurovarieties
arXiv:2511.19703v2 Announce Type: replace-cross Abstract: We study the dimension and identifiability of neurovarieties associated to polynomial neural networks. We give an independent geometric proof that the linear boun…
Group-averaged Markov chains II: tuning of group action in finite state space
arXiv:2512.13067v2 Announce Type: replace-cross Abstract: We study group-averaged Markov chains obtained by augmenting a $\pi$-stationary kernel $P$ with orbit kernels induced by a group action. We analyse the Gibbs ($G$…
Modeling Information Blackouts in Missing Not-At-Random Time Series Data
arXiv:2601.01480v3 Announce Type: replace-cross Abstract: Traffic forecasting systems rely on fixed sensor networks that frequently exhibit contiguous blackouts. Such outages are usually treated as ignorable missingness,…
The Replicator-Optimization Mechanism: A Scale-Relative Formalism for Persistence-Conditioned Dynamics with a Conditional Consent-Friction Instantiation
arXiv:2601.06363v4 Announce Type: replace-cross Abstract: Persistence models often conflate propagation, survival, and cross-scale loss. The Replicator-Optimization Mechanism (ROM) is a replicator-mutator template separa…
Auditing Frozen-Encoder Anomaly Detection Across Mechanical Systems: Representation Provenance, Calibration, and Protocol Effects
arXiv:2601.11415v2 Announce Type: replace-cross Abstract: This version reports a reproducibility audit of the frozen-encoder experiments presented in version 1. The numerical discrimination results are reproducible from …
Denoising the Deep Sky: Physics-Based CCD Noise Formation for Astronomical Imaging
arXiv:2601.23276v4 Announce Type: replace-cross Abstract: Astronomical imaging remains noise-limited under practical observing conditions. Standard calibration pipelines remove structured artifacts but largely leave stoc…
Persistent Entropy as a Detector of Phase Transitions
arXiv:2602.09058v2 Announce Type: replace-cross Abstract: Persistent entropy is a scalar summary of persistence barcodes widely used to detect regime changes, yet there is no account of when a structural change in a barc…
Observer-robust energy condition verification for warp drive spacetimes
arXiv:2602.18023v5 Announce Type: replace-cross Abstract: Whether a warp drive metric requires exotic matter is decided by energy conditions quantified over all observers, not only the Eulerian. Each of the null, weak, s…
Rethinking quantum smooth entropies: Tight one-shot analysis of quantum privacy amplification
arXiv:2603.04493v4 Announce Type: replace-cross Abstract: We introduce an improved one-shot characterisation of randomness extraction against quantum side information (privacy amplification), strengthening known one-shot…
Reconstruct! Don't Encode: Self-Supervised Representation Reconstruction Loss for High-Intelligibility and Low-Latency Streaming Neural Audio Codec
arXiv:2603.05887v2 Announce Type: replace-cross Abstract: Neural audio codecs optimized for mel-spectrogram reconstruction often fail to preserve intelligibility. While semantic encoder distillation improves encoded repr…
