*WSO2 Machine Learner 1.0.0 Released*

*September, 2015*

Machine learning has emerged as a key component of big data analytics
space. The goal of WSO2 Machine Learner is to make machine learning
accessible to WSO2 big data platform. WSO2 Machine Learner provides a user
friendly wizard like interface, which guides users through a set of steps
to find and configure machine learning algorithms. The outcome of this
process is a model that can be deployed in multiple WSO2 products, such as
WSO2 Enterprise Service Bus (ESB), WSO2 Complex Event Processor (CEP), WSO2
Data Analytics Server (DAS) etc.

The novice-friendly machine learning analysis allows developers, data
scientists and database administrators to quickly implement machine
learning methods. You can utilize WSO2 Machine Learner to build machine
learning models for various tasks, such as fraud detection, anomaly
detection, classification etc. WSO2 Machine Learner is built up on the
award-winning, WSO2 Carbon platform, which is based on the OSGi framework
enabling better modularity for your service oriented architecture (SOA).

This is the 1.0.0 release of WSO2 Machine Learner product and is released
under Apache Software License Version 2.0, one of the most
business-friendly licenses available today.
