    Recursive Linear Estimation for Discrete-Time Systems in the Presence of Different Multiplicative Observation Noises by C. Sánchez-González, T. M. García-Muñoz

    Published 2010-01-01
    “…This paper describes a design for a least mean square error estimator in discrete time systems where the components of the state vector, in measurement equation, are corrupted by different multiplicative noises in addition to observation noise. We show how known results can be considered a particular case of the algorithm stated in this paper.…”

    Robust High-Gain Observers Based Liquid Levels and Leakage Flow Rate Estimation by Feten Smida, Salim Hadj Saïd, Faouzi M’sahli

    Published 2018-01-01
    “…We have proposed a state repartition that allows putting the model of the quadruple tank system to the canonical form for which the design of the observer is more easier. The observation scheme that uses a combination of high-gain observers and sliding mode observers allows improving robustness in the state estimation quality and a perfect reconstruction of the disturbance waveforms.…”

    dotears: Scalable and consistent directed acyclic graph estimation using observational and interventional data by Albert Xue, Jingyou Rao, Sriram Sankararaman, Harold Pimentel

    Published 2025-02-01
    “…Causal regulatory networks can be represented by directed acyclic graphs (DAGs), but lack of identifiability and a combinatorial solution space complicate learning DAGs from observational data. Score-based methods have improved the practical scalability of inferring DAGs, but are sensitive to error variance structure. …”
