Skytree, Inc is a San Jose, California-based startup company that develops machine learning software for enterprise use. Skytree came out of stealth mode in February 2012. announcing Skytree Server, a machine learning system to discover patterns and make predictions from complex, massive data.
The company was co-founded by Martin Hack, Alexander Gray, Abhimanyu Aditya and Ryan Riegel.In April 2013, Skytree raised $18 million in Series A funding. The round was led by U.S. Venture Partners. Scott McNealy, co-founder and former chief executive at Sun Microsystems, also participated. Other investors include Javelin Venture Partners, UPS, and Osage University Partners.
Skytree has machine learning methods that include: random decision forests, kernel density estimation, K-means, singular value decomposition, gradient boosting, decision tree, 2-point correlation, range searching, K-nearest neighbors algorithm, linear regression, support vector machine, and logistic regression.Skytree Server software operates in Linux on a single server computer or multi node cluster, and is intended for use by modelers for development of machine learning models, and for production deployments (in real time or batch usage). It is designed to connect with existing IT infrastructure. It can be configured to accept data streams and compute results from multiple sources. The resulting analytics are returned through the same channels.
Standard data sources include both structured and unstructured data from:
Relational Databases (RDBMS)
Hadoop Systems (HDFS)
Flat file databases (e.g. CSV)Skytree Adviser software finds an appropriate model fit to given data, and explains its findings to the user in ordinary language. It includes methods found in statistics packages like regression analysis, analysis of variance and cluster analysis. It provides a graphical user interface that emphasizes tasks (such as cluster, classify or compare) over algorithms and includes short explanations of the underlying statistical methods.
Adviser reads file formats including files with the following extensions: TXT, CSV, DAT, GML, XML, NET, PDF, ODT, DOX. It can also read database files from MySQL, Oracle Database, Microsoft SQL Server, IBM DB2, and Teradata. The software runs on macOS, Windows, and Linux.
Skytree customers include:
United States Golf Association
Canadian Advanced Network for Astronomical Research (CANFAR)
