Reconstructing Visual Appearance and Process by Repurposing Pretrained Diffusion Models
… often arise in regimes where the available observations are incomplete or indirect. Inputs may capture only fragments of visual appearance, or omit the intermediate processes that produced the final result, yet models are expected to synthesize outputs that are visually complete, coherent, …

Multi-agent Coordination Algorithms for Pursuit-Evasion
… the multi-agent task; (4) how to overcome the partial observation; and (5) how to get the arms race from the adversarial co-evolution. Accordingly, a safety-constrained multi-agent pursuit-evasion platform: MatrixWorld is proposed, and three coordination algorithms are designed, i.e., the …

A multiresolution approach for tensor completion from coarse and partial observations
… tensor completion formulation mostly relies on partial observations from a single tensor. However, tensors extracted from real-world data often are more complex due to: (i) Partial observation: Only a small subset of tensor elements are available. (ii) Coarse observation: Some tensor modes only …

Verification and Enforcement of State-Based Notions of Opacity in Discrete Event Systems
… non-deterministic) finite automata with partial observation on their transitions. Assuming that the intruder observes system activity through some projection map and has complete knowledge of the system model, we define three notions of opacity with respect to a set of secret states: (i) …

Thermodynamic and topological characterization of living systems
… data, which are often noisy and represent only a partial observation of the system. One such challenge is to estimate the rate at which a system is consuming free energy. All living systems must consume free energy to maintain or increase local order, and theoretical models can provide insights …

Particle Filtering for Stochastic Control and Global Optimization
… control, an important class of problems, namely, partially observable Markov decision processes (POMDPs), provides an ideal paradigm to model discrete-time sequential decision making under uncertainty and partial observation. However, POMDPs usually do not admit analytical solutions, and are …

Opacity Of Discrete Event Systems: Analysis And Control
… modeled as</p> <p>a discrete event system with partial observation mapping. We define three types of</p> <p>opacity: strong opacity, weak opacity, and no opacity. Strong Opacity describes the</p> <p>inability for the system's observer to know what happened in a system. On the other</p> <p>hand, …

Optimal estimation in high-dimensional and nonparametric models
… estimating the volume of a set in $R^d$ based on observations of points uniformly distributed over the set. The framework applies to all classes of sets satisfying one simple axiom: a class is assumed to be intersection stable. No further hypotheses on the boundary of the set are imposed; in …

Domain-based Frameworks and Embeddings for Dynamics over Networks
… guarantee, for inferring network states given a partial observation of the failures in networks. Additionally, by exploiting domain-aware embeddings, we outperform non-trivial competitors by up to 40% for influenza forecasting. Similarly, domain-aware representations of subgraphs helped us …

A NEW ZEROTH-ORDER ORACLE FOR DISTRIBUTED AND NON-STATIONARY LEARNING
… of the global accumulated rewards that depend on partial state and action information only and can be obtained using consensus. Specifically, the local ZO policy gradients relying on one-point residual-feedback significantly reduces the vari- ance of the local policy gradient estimates compared to …

Control and diagnosis of real-time systems under finite-precision measurement of time
