PAC-Bayes Generalisation Bounds for Dynamical Systems Including Stable RNNs

1 code implementation15 Dec 2023 Deividas Eringis, John Leth, Zheng-Hua Tan, Rafal Wisniewski, Mihaly Petreczky

In this paper, we derive a PAC-Bayes bound on the generalisation gap, in a supervised time-series setting for a special class of discrete-time non-linear dynamical systems.

PAC-Bayesian bounds for learning LTI-ss systems with input from empirical loss

no code implementations29 Mar 2023 Deividas Eringis, John Leth, Zheng-Hua Tan, Rafael Wisniewski, Mihaly Petreczky

In this paper we derive a Probably Approxilmately Correct(PAC)-Bayesian error bound for linear time-invariant (LTI) stochastic dynamical systems with inputs.

Economic Predictive Control with Periodic Horizon for Water Distribution Networks

no code implementations31 Jan 2023 Mirhan Ürkmez, Carsten Kallesøe, Jan Dimon Bendtsen, John Leth

This paper deals with the control of pumps in large-scale water distribution networks with the aim of minimizing economic costs while satisfying operational constraints.

PAC-Bayesian-Like Error Bound for a Class of Linear Time-Invariant Stochastic State-Space Models

no code implementations30 Dec 2022 Deividas Eringis, John Leth, Zheng-Hua Tan, Rafal Wisniewski, Mihaly Petreczky

In this paper we derive a PAC-Bayesian-Like error bound for a class of stochastic dynamical systems with inputs, namely, for linear time-invariant stochastic state-space models (stochastic LTI systems for short).

An Online Stochastic Optimization Approach for Insulin Intensification in Type 2 Diabetes with Attention to Pseudo-Hypoglycemia

1 code implementation24 Apr 2022 Mohamad Al Ahdab, Torben Knudsen, Jakob Stoustrup, John Leth

In this paper, we present a model free approach to calculate long-acting insulin doses for Type 2 Diabetic (T2D) subjects in order to bring their blood glucose (BG) concentration to be within a safe range.

Explicit construction of the minimum error variance estimator for stochastic LTI state-space systems

no code implementations6 Sep 2021 Deividas Eringis, John Leth, Zheng-Hua Tan, Rafal Wisniewski, Mihaly Petreczky

In this short article, we showcase the derivation of the optimal (minimum error variance) estimator, when one part of the stochastic LTI system output is not measured but is able to be predicted from the measured system outputs.

Glucose-insulin mathematical model for the combined effect of medications and life style of Type 2 diabetic patients

no code implementations4 Aug 2020 Mohamad Al Ahdab, John Leth, Torben Knudsen, Peter Vestergaard, Henrik Clausen

Additionally, a discussion is provided to demonstrate the ability of the model to be used in the assessment of treatment plans and in the design for robust insulin dose guidance algorithms.
