Effects of radiation, curvature, and preferential diffusion on the extinction of laminar non-premixed flames
Published 2022-11-01“…The combined effects of radiative heat loss, curvature, and preferential diffusion on laminar non-premixed flames (or flamelets) are investigated in this work by using asymptotic analysis. A general theoretical description of flame temperature and extinction is derived for curved flames with non-unity Lewis numbers and radiative heat loss. …”

An online optimization approach for multi-agent tracking of dynamic parameters in the presence of adversarial noise
Published 2018“…We then propose a decentralized version of the Mirror Descent algorithm and provide the non-asymptotic analysis of the problem. Using the notion of dynamic regret, we measure the performance of our algorithm versus its offline counterpart in the centralized setting. …”

Dynamic Clustering Algorithms via Small-Variance Analysis of Markov Chain Mixture Models
Published 2022“…A recently developed methodology in this field is small-variance asymptotic analysis, a mathematical technique for deriving learning algorithms that capture much of the flexibility of Bayesian nonparametric inference algorithms, but are simpler to implement and less computationally expensive. …”

Optimal criteria and their asymptotic form for data selection in data-driven reduced-order modelling with Gaussian process regression
Published 2024“…We combine results from GPR theory and asymptotic analysis to derive a computable form of the defined optimality criterion that is valid in the limit of small predictive variance. …”

Tilted biorthogonal ensembles, Grothendieck random partitions, and determinantal tests
Published 2024“…This identification expresses the correlation functions of Grothendieck measures through sums of Fredholm determinants, which are not immediately suitable for asymptotic analysis. A more direct approach allows us to obtain a limit shape result for the Grothendieck random partitions. …”

Free Energy Fluctuations for Directed Polymers in Random Media in 1 + 1 Dimension
Published 2015“…We consider two models for directed polymers in space-time independent random media (the O'Connell-Yor semidiscrete directed polymer and the continuum directed random polymer) at positive temperature and prove their KPZ universality via asymptotic analysis of exact Fredholm determinant formulas for the Laplace transform of their partition functions. …”

A modular framework for centrality and clustering in complex networks
Published 2023“…Our principal contributions include (1) a generalized model of Markov entropic centrality with the flexibility to tune the importance of node degrees, edge weights and directions, with a closed-form asymptotic analysis, which (2) leads to a novel two-stage graph clustering algorithm. …”

Merging ring-structured overlay indices : toward network-data transparency
Published 2013“…We introduce interesting new metrics to evaluate the merger process and carry out asymptotic analysis for estimating the same, besides conducting simulation experiments to validate the theory as well as measure other aspects of the overlays’ performance under merger.…”

Analysis of complete contacts subject to fatigue
Published 2015“…First, because fretting failures almost invariably initiate from the edge of contact, a detailed understanding of the conditions in this region should enable more accurate assessments of fatigue performance to be made. Thus, an asymptotic analysis is presented, which provides an accurate description of the contact edge under many conditions. …”

Reliable automatic model reduction combining a posteriori error analysis and a posteriori model reduction
Published 2019“…In particular, I can show with that example that the reduced models which were automatically generated correspond to those obtained by asymptotic analysis. The same elucidation of the processes that are modelled could therefore be achieved with the automatic model reduction technique as with methods that usually need considerable mathematical expertise.…”

Deep neural networks with dependent weights: Gaussian process mixture limit, heavy tails, sparsity and compressibility
Published 2023“…Many sparsity-promoting neural network models can be recast as special cases of our approach, and we discuss their infinite-width limits; we also present an asymptotic analysis of the pruning error. We illustrate some of the benefits of the MoGP regime over the GP regime in terms of representation learning and compressibility on simulated, MNIST and Fashion MNIST datasets.…”
