Sampling the Variational Posterior with Local Refinement [PDF]
Entropy, 2021 Variational inference is an optimization-based method for approximating the posterior distribution of the parameters in Bayesian probabilistic models. A key challenge of variational inference is to approximate the posterior with a distribution that is ...

Local refinement mechanism for improved plant leaf segmentation in cluttered backgrounds [PDF]
Frontiers in Plant Science, 2023 Plant phenotyping is a critical field in agriculture, aiming to understand crop growth under specific conditions. Recent research uses images to describe plant characteristics by detecting visual information within organs such as leaves, flowers, stems ...

Brain SegNet: 3D local refinement network for brain lesion segmentation [PDF]
BMC Medical Imaging, 2020 MR images (MRIs) accurate segmentation of brain lesions is important for improving cancer diagnosis, surgical planning, and prediction of outcome. However, manual and accurate segmentation of brain lesions from 3D MRIs is highly expensive, time-consuming,

Non-sequential protein structure alignment by conformational space annealing and local refinement. [PDF]
PLoS ONE, 2019 Protein structure alignment is an important tool for studying evolutionary biology and protein modeling. A tool which intensively searches for the globally optimal non-sequential alignments is rarely found. We propose ALIGN-CSA which shows improvement in

Proceedings of the ACM on Programming Languages, 2017 We introduce the FUSION algorithm for local refinement type inference, yielding a new SMT-based method for verifying programs with polymorphic data types and higher-order functions. FUSION is concise as the programmer need only write signatures for (externally exported) top-level functions and places with cyclic (recursive) dependencies, after which ...

Locally Refined T‐splines [PDF]
International Journal for Numerical Methods in Engineering, 2018 SummaryWe extend Locally Refined (LR) B‐splines to LR T‐splines within the Bézier extraction framework. This discretization technique combines the advantages of T‐splines to model the geometry of engineering objects exactly with the ability to flexibly carry out local mesh refinement.
