Self-Organizing Maps

Self-Organizing Maps

Teuvo Kohonen (2001) Springer Verlag, Third Edition

This is the basic monograph and standard lecture book about self-organizing maps (SOMs) by Teuvo Kohonen, the originator of the subject.

SOM, with its variants, is the most popular artificial neural network algorithm in the unsupervised learning category. Many fields of science, including statistics, signal processing, control theory, financial analyses, experimental physics, chemistry and medicine, have adopted the SOM as a standard analytical tool.

Viscovery SOMine is reviewed as a commercial standard tool for creating SOM applications.

Kohonen Maps

Kohonen Maps

Erkki Oja, Samuel Kaski; Contributor Erkki Oja and Samuel Kaski (1999), Elsevier

Top experts in the SOM method cover the state of the art and the future of theory. The thirty chapters of this book cover the current status of SOM theory, such as the role of SOMs in clustering, classification, probabilistic models, and energy functions. Many SOM applications are described, with an emphasis on data mining and exploratory data analysis as applied to large databases of financial data, medical data, free-form text documents, digital images, speech, and process measurements. Biological models related to the SOM are discussed as well.

Supply Chain Management

Unlocking successful new rural industries: Is supply chain management the key?

Collins and Lim-Camacho (2005) Rural Industries Research and Development Corporation (Publication No 05/139)

This final report to the Rural Industries Research and Development Corporation addresses the role of supply-chain management as a business strategy in the development of five new rural industries in Australia. The report demonstrates that in new rural industries, firms with medium to high levels of supply chain management thinking, planning, and implementation are more successful in terms of creating value and achieving competitive advantage than those with lower levels of supply-chain management.

Viscovery SOMine, SPSS, and qualitative analysis were used to elucidate patterns across different supply-chain case studies. Clustering revealed how unique characteristics of individual cases combine to exhibit distinct patterns of similarities and differences.

Performance Management and Analytics – Business Intelligence and the Digital Enterprise.

Wolfgang Martin (2015) Wolfgang Martin Team

Business Intelligence is defined via its two mainstreams: performance management and analytics. Today, in the digital age, it must respond to the challenges of agile, smart and data-driven organizations. Performance management is needed for unerring monitoring and controlling of business processes, and analytics, in particular Big Data analytics, must improve competitiveness in extremely dynamic and volatile markets moving towards the Internet of Things.

Viscovery SOMine is positioned in the market segment of software tools for predictive analytics and data mining.
