Using Self-Organizing Maps to Calculate Chilling Hours as an Indicator of Temperature Shifts During Winter in the Southeastern United States
… project involves training self-organizing maps (SOMs) to identify periods of anomalous winter warming based on a reduced number of chill hours within a 5-day temporal period compared to the period's climatological average. A second SOM is nested in the node that produced the most anomalous events …

Emotion Focused Couples Therapy as a Treatment of Somatoform Disorders: An Outcome Study
… Somatoform Disorder as determined by the SOMS and who scored less than or equal to 101 on the Dyadic Adjustment Scale participated in this study. These couples were randomly assigned to 8 sessions of emotionally focused therapy or to a 12-week wait list condition. The purpose of the study …

A systematic study of offline recognition of Thai printed and handwritten characters
… (NECTEC) uses Kohonen self-<br/>organising maps (SOMs) for rough classification and back-propagation neural networks for fine classification. An evaluation of the NECTEC OCR is performed on a printed dataset that contains over 0.6 million tokens. Comparisons of the classifier, with and without the …

Arctic synoptic activity associated with sea ice variability using self-organizing maps
… Arctic are studied using self-organizing maps (SOMs) to categorize observed weather patterns over the 1979-2010 period. The European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-interim, or ERAI) provides the daily sea level pressures from which the SOMs are computed. Time …

Analyzing Freight Congestion and Transportation Performance Measures Using the National Performance Management Research Data Set (NPMRDS)
… machine learning method, Self-Organizing Maps (SOMs), is applied to classify weather attributes. The last phase is performance based (using TTI, PTI, BI, TED obtained in previous research) classification of segments by using SOMs, and cases studies for labelled groups.</p>

Improving integrated wildfire management in the Fynbos Biome of South Africa using information on synoptic-scale atmospheric features that promote wildfires
… horizontal resolution. The Self Organising Maps (SOMs) technique was used to classify the FDI (anomaly) patterns on the fire days, and the atmospheric dynamics associated with each pattern were studied.

The synoptic drivers of extreme rainfall in South Africa
… of extreme rainfall. Self-organizing maps (SOMs) were used to characterize the synoptic circulations on a general country-wide scale as well as for 8 different regional rainfall regimes at a seasonal scale. Synoptic circulations associated with extreme rainfall events often involved an …

Development of mass spectrometry based technologies for quantitative cell signaling phosphoproteomics : the epidermal growth factor receptor family as a model system
… receptor (EGFR) family. Self organizing maps (SOMs) analysis of our data has highlighted potential biological functions for phosphorylation sites previously unrelated to EGFR signaling and identified network modules regulated by different combinations of EGFR family members. Partial least …

Assisted auscultation : creation and visualization of high dimensional feature spaces for the detection of mitral regurgitation
… Our system employs self-organizing maps (SOMs) to depict the distribution of patients in each feature space as labels within a two-dimensional colored grid. A user screens new patients by viewing their projections onto the SOM, and determining whether they are closer in space, and thus …

Approaches to quantifying and reducing uncertainty in GCMs over Southern Africa
… for other regions. Using Self-Organising Maps (SOMs), synoptic archetypal patterns are identified and the distribution and frequency of these patterns assessed. The use of synoptic archetypes to quantify model metrics presents a novel approach with many benefits over standard metrics, such as …

An examination of the spatially extensive heavy precipitation events over South Africa and the associated moisture trajectories
… technique called Self Organising Maps (SOMs). A number of groups were identified through this process and sample events from this were then further analysed with the use of a kinematic trajectory model. The results indicated that moisture for these events were most likely to be …
