Free-Probability Kernels for Zero-Rollout Hyperparameter Selection in Reservoir Computing

Sara Malacarne, Andrea Ceni, Claudio Gallicchio

Reservoir computing (RC) couples a fixed recurrent dynamical system with a trained lightweight readout, but this efficiency is partly lost during hyperparameter selection: the recu…

Closing the Gap Between Synthetic and Ground Truth Time Series Distributions via Neural Mapping

Daesoo Lee, Sara Malacarne, Erlend Aune

In this paper, we introduce Neural Mapper for Vector Quantized Time Series Generator (NM-VQTSG), a novel method aimed at addressing fidelity challenges in vector quantized (VQ) tim…

Explainable Time Series Anomaly Detection using Masked Latent Generative Modeling

Daesoo Lee, Sara Malacarne, Erlend Aune

We present a novel time series anomaly detection method that achieves excellent detection accuracy while offering a superior level of explainability. Our proposed method, TimeVQVAE…

Masked Generative Modeling with Enhanced Sampling Scheme

Daesoo Lee, Erlend Aune, Sara Malacarne

This paper presents a novel sampling scheme for masked non-autoregressive generative modeling. We identify the limitations of TimeVQVAE, MaskGIT, and Token-Critic in their sampling…

Vector Quantized Time Series Generation with a Bidirectional Prior Model

Daesoo Lee, Sara Malacarne, Erlend Aune

Time series generation (TSG) studies have mainly focused on the use of Generative Adversarial Networks (GANs) combined with recurrent neural network (RNN) variants. However, the fu…

Martin boundaries of the duals of free unitary quantum groups

Sara Malacarne, Sergey Neshveyev

Given a free unitary quantum group , with not a unitary -by- matrix, we show that the Martin boundary of the dual of with respect to any --invari…

Probabilistic boundaries of finite extensions of quantum groups

Sara Malacarne, Sergey Neshveyev

Given a discrete quantum group with a finite normal quantum subgroup , we show that any positive, possibly unbounded, harmonic function on with respect to an irreducible…
