| The Algorithm Development and Mining (ADaM) system is designed with the goal of mining large scientific data sets for geophysical phenomena detection and feature extraction, and has continued to be expanded and improved for over 10 years. ADaM’s mining and image processing toolkits consist of over 100 interoperable components that can be linked together in a variety of ways for application to diverse problem domains. ADaM includes not only traditional data mining capabilities such as pattern recognition, but also image processing and optimization capabilities, and many supporting data preparation algorithms that are useful in the mining process. Each component is provided with a C, C++, or other application programming interface (API), an executable in support of generic scripting tools (e.g. Perl, Python, shell scripts) and SOAP web service interfaces to support distributed architectures including web and grid applications. The ADaM toolkit is also available as a suite of SOAP web services. WSDL documents are available. | ||
