Minimal Realization Problems for Hidden Markov Models

no code implementations13 Nov 2014 Qingqing Huang, Rong Ge, Sham Kakade, Munther Dahleh

Consider a stationary discrete random process with alphabet size d, which is assumed to be the output process of an unknown stationary Hidden Markov Model (HMM).

Real-Time Decoding of an Integrate and Fire Encoder

no code implementations NeurIPS 2014 Shreya Saxena, Munther Dahleh

Neuronal encoding models range from the detailed biophysically-based Hodgkin Huxley model, to the statistical linear time invariant model specifying firing rates in terms of the extrinsic signal.

Learning Good State and Action Representations via Tensor Decomposition

no code implementations3 May 2021 Chengzhuo Ni, Yaqi Duan, Munther Dahleh, Anru Zhang, Mengdi Wang

The transition kernel of a continuous-state-action Markov decision process (MDP) admits a natural tensor structure.

QuickFlex: a Fast Algorithm for Flexible Region Construction for the TSO-DSO Coordination

no code implementations30 Jun 2021 Luis Lopez, Alvaro Gonzalez-Castellanos, David Pozo, Mardavij Roozbehani, Munther Dahleh

For unlocking such capabilities, it is essential to understand the aggregated flexibility that can be harvested from the large population of new technologies located in distribution grids.

Causal Matrix Completion

no code implementations30 Sep 2021 Anish Agarwal, Munther Dahleh, Devavrat Shah, Dennis Shen

In particular, we establish entry-wise, i. e., max-norm, finite-sample consistency and asymptotic normality results for matrix completion with MNAR data.

SAMoSSA: Multivariate Singular Spectrum Analysis with Stochastic Autoregressive Noise

no code implementations NeurIPS 2023 Abdullah Alomar, Munther Dahleh, Sean Mann, Devavrat Shah

However, a theoretical underpinning of multi-stage learning algorithms involving both deterministic and stationary components has been absent in the literature despite its pervasiveness.

Open-Ended Question Answering Time Series +1

Estimation of Models with Limited Data by Leveraging Shared Structure

no code implementations4 Oct 2023 Maryann Rui, Thibaut Horel, Munther Dahleh

Modern data sets, such as those in healthcare and e-commerce, are often derived from many individuals or systems but have insufficient data from each source alone to separately estimate individual, often high-dimensional, model parameters.

Sample Efficient Reinforcement Learning with Partial Dynamics Knowledge

1 code implementation19 Dec 2023 Meshal Alharbi, Mardavij Roozbehani, Munther Dahleh

In the setting of finite episodic Markov decision processes with $S$ states, $A$ actions, and episode length $H$, we present an optimistic Q-learning algorithm that achieves $\tilde{\mathcal{O}}(\text{Poly}(H)\sqrt{T})$ regret under perfect knowledge of $f$, where $T$ is the total number of interactions with the system.
