Counterfactual Forecasting of Human Behavior using Generative AI and Causal Graphs

arXiv:2511.07484v1 Announce Type: new Abstract: This study presents a novel framework for counterfactual user behavior forecasting that combines structural causal models with transformer-based generative artificial intelligence. To model fictitious situations, the method creates causal graphs that map the connections between…

Multivariate Variational Autoencoder

arXiv:2511.07472v1 Announce Type: new Abstract: We present the Multivariate Variational Autoencoder (MVAE), a VAE variant that preserves Gaussian tractability while lifting the diagonal posterior restriction. MVAE factorizes each posterior covariance, where a emph{global} coupling matrix $mathbf{C}$ induces dataset-wide latent correlations…

Towards Personalized Quantum Federated Learning for Anomaly Detection

arXiv:2511.07471v1 Announce Type: new Abstract: Anomaly detection has a significant impact on applications such as video surveillance, medical diagnostics, and industrial monitoring, where anomalies frequently depend on context and anomaly-labeled data are limited. Quantum federated learning (QFL) overcomes these concerns…

Provably Efficient Sample Complexity for Robust CMDP

arXiv:2511.07486v1 Announce Type: new Abstract: We study the problem of learning policies that maximize cumulative reward while satisfying safety constraints, even when the real environment differs from a simulator or nominal model. We focus on robust constrained Markov decision processes…
