Предлагается новый метод быстрого поиска закономерностей в числовых данных большой раз-мерности, названный “туннельной кластеризацией”. Основными преимуществами нового методаявляются: относительно невысокая вычислительная сложность; эндогенное определение составаи количества кластеров; высокая степень интерпретируемости конечных результатов. Приведеноописание трех различных вариаций: с фиксированными гиперпараметрами, адаптивными, а так-же комбинированный подход. Рассмотрены три основных свойства туннельной кластеризации.Практическое применение приведено как на синтетических ...

В статье исследуются природно-социально-экономические объекты - АПК и сельские территории в составе единой системы. Практическая реализация системного подхода позволила представить указанные объекты как системообразующие компоненты аграрно-территориальных систем (АТС) с тремя ключевыми подсистемами: природной, социальной, экономической. Целью работы выступило многоуровневое стратифицированное позиционирование АТС регионов России. Гипотеза исследования состоит в установлении возможности определения общих паттернов развития для ...

Lateral heterogeneity, or mosaicity, is a fundamental property inherent to cell membranes that is crucial for their functioning. While microscopic inhomogeneities (e.g. rafts) are easily detected experimentally, lipid domains with nanoscale dimensions (nanoclusters of nanodomains, NDs) resist reliable characterization by instrumental methods. In such a case, important insight can be gained via computer modeling. Here, ...

Working memory (WM) is a cognitive function essential for short-term maintenance of information in a highly accessible state to support goal-directed behavior. The classical behavioral model of WM includes a visuospatial sketchpad, a phonological loop and the central executive. Neuroimaging studies selectively targeted the activity associated with maintenance and processing of modality specific information. However, an experimental design is still missing that would ...
