2.4 Sea Surface Temperature Patterns on the West Florida Shelf Using Growing Hierarchical Self-organizing Maps
The West Florida Shelf (WFS) is a broad, gently sloping continental margin that is influenced by the Gulf of Mexico Loop Current system located seaward of the shelf break (Molinari et al., 1977; Huh et al., 1981; Paluszkiewicz et al., 1983; He and Weisberg, 2003; Weisberg and He, 2003) and by local wind and buoyancy forcing, including the fresh water of the Mississippi River, generally found at...
متن کاملSea Surface Temperature Patterns on the West Florida Shelf Using Growing Hierarchical Self-Organizing Maps
Neural network analyses based on the self-organizing map (SOM) and the growing hierarchical selforganizing map (GHSOM) are used to examine patterns of the sea surface temperature (SST) variability on the West Florida Shelf from time series of daily SST maps from 1998 to 2002. Four characteristic SST patterns are extracted in the first-layer GHSOM array: winter and summer season patterns, and tw...
متن کاملPatterns of ocean current variability on the West Florida Shelf using the self-organizing map
[1] Patterns of ocean current variability are examined on the West Florida Shelf by a neural network analysis based on the self-organizing map (SOM), using time series of moored velocity data that span the interval October 1998–September 2001. Three characteristic spatial patterns are extracted in a 3 4 SOM array: spatially coherent southeastward and northwestward flow patterns with strong curr...
متن کاملUsing Growing hierarchical self-organizing maps for document classification
The self-organizing map has shown to be a stable neural network model for high-dimensional data analysis. However, its applicability is limited by the fact that some knowledge about the data is required to de ne the size of the network. In this paper we present the Growing Hierarchical SOM. This dynamically growing architecture evolves into a hierarchical structure of self-organizing maps accor...

شبکه خود سازمانده پرکاربردترین شبکه عصبی برای انجام خوشه بندی و کوانتیزه نمودن برداری است. از زمان معرفی این شبکه تاکنون، از این روش در مسائل مختلف در حوزه های گوناگون استفاده و توسعه ها و بهبودهای متعددی برای آن ارائه شده است. شبکه خودسازمانده از تعدادی سلول برای تخمین تابع توزیع الگوهای ورودی در فضای چندبعدی استفاده می کند. احتمال وجود سلول مرده مشکلی اساسی در الگوریتم شبکه خودسازمانده به حسا...
