The permutation group of Reed-Solomon codes over arbitrary points
arXiv:2601.00122v1 Announce Type: new Abstract: In this work, we prove that the permutation group of a Reed-Solomon code is given by the polynomials of degree one that leave the set of evaluation points invariant. Our results provide a straightforward proof of the well-known cases of the permutation group of the Reed-Solomon code when the set of evaluation points is the whole finite field or the multiplicative group.

MIT scientists investigate memorization risk in the age of clinical AI
What is patient privacy for? The Hippocratic Oath, thought to be one of the earliest and most widely known medical ethics texts in the world, reads: “Whatever I see or hear in the lives of my patients, whether in connection with my professional practice or not, which ought not to be spoken of outside, I will keep secret, as considering all such things to be private.” As privacy becomes increasingly scarce in the age of data-hungry algorithms and […]

On the Identifiability of Regime-Switching Models with Multi-Lag Dependencies
arXiv:2601.03325v1 Announce Type: new Abstract: Identifiability is central to the interpretability of deep latent variable models, ensuring parameterisations are uniquely determined by the data-generating distribution. However, it remains underexplored for deep regime-switching time series. We develop a general theoretical framework for multi-lag Regime-Switching Models (RSMs), encompassing Markov Switching Models (MSMs) and Switching Dynamical Systems (SDSs). For MSMs, we formulate the model as a temporally structured finite mixture and prove identifiability of both the number of regimes and the […]

Comparative Performance of Deep Learning Models for Financial Statement Fraud Detection in an Imbalanced Classification Setting
Financial statement fraud continues to pose a significant challenge to audit effectiveness, investor confidence, and the integrity of financial markets. Fraud detection is particularly complex due to the highly imbalanced nature of financial reporting data, where fraudulent observations constitute only a small fraction of the total sample. In such settings, conventional accuracy-based evaluation often produces misleading conclusions and fails to reflect practical audit value. This study conducts a comparative evaluation of four deep learning models, namely LSTM, GRU, […]

Understanding LSTM Networks
Humans don’t start their thinking from scratch every second. As you read this essay, you understand each word based on your understanding of previous words. You don’t throw everything away and start thinking from scratch again. Your thoughts have persistence. Traditional neural networks can’t do this, and it seems like a major shortcoming. For example, imagine you want to classify what kind of event is happening at every point in a movie. It’s unclear how a traditional neural […]
