Simultaneously Reconciled Quantile Forecasting of Hierarchically Related Time Series
Xing Han, Sambarta Dasgupta, Joydeep Ghosh
Many real-life applications involve simultaneously forecasting multiple time series that are hierarchically related via aggregation or disaggregation operations. For instance, comm…
Particle Clustering Machine: A Dynamical System Based Approach
Sambarta Dasgupta, Keivan Ebrahimi, Umesh Vaidya
Identification of the clusters from an unlabeled data set is one of the most important problems in Unsupervised Machine Learning. The state of the art clustering algorithms are bas…
Contingency Analysis of Power Networks : A System Theoretic Approach
Sambarta Dasgupta, Umesh Vaidya
In this work, we have proposed a system theoretic method to compute sensitivities of different lines for contingency analysis in power network. We have formulated the c…
Normally hyperbolic surfaces based finite-time transient stability monitoring of power system dynamics
Sambarta Dasgupta, Umesh Vaidya
In this paper, we develop a methodology for finite time rotor angle stability analysis using the theory of normal hyperbolic surfaces. The proposed method would bring new insights…
Actuator and sensor placement in linear advection PDE with building system applications
Umesh Vaidya, Rajeev Rajaram, Sambarta Dasgupta
We study the problem of actuator and sensor placement in a linear advection partial differential equation (PDE). The problem is motivated by its application to actuator and sensor…
Control of systems in Lure form over erasure channel
Amit Diwadkar, Sambarta Dasgupta, Umesh Vaidya
In this paper, we study the problem of control of discrete-time nonlinear systems in Lure form over erasure channels at the input and output. The input and output channel uncertain…
