Waffles – command-line tools for machine learning and data mining

Brent Sordyl — Thu, 05 Jan 2012 21:06:31 +0000

Waffles seeks to be the world’s most comprehensive collection of command-line tools for machine learning and data mining. Our native tools have minimal dependencies (no interpreter, VM, or runtime environment is necessary), and build cross-platform. If you have a useful data mining tool that meets these criteria, we want it in Waffles.

Black Duck – Open Source, Abundance and Open Innovation

Brent Sordyl — Mon, 12 Dec 2011 21:06:52 +0000

With open source comes abundance — more than 500,000+ projects are freely available today, and that number’s growing rapidly. Clearly the confluence between developers, communities and businesses turning to open source has provided a way for enterprises to grow and speed development, even with constrained resources.

Evaluating Text Extraction Algorithms

According to my evaluation setup and personal experience, the best open source solution currently available on the market is the boilerpipe library. If we treat precision with an equal amount of importance as recall (reflected in the F1 score) and take into account the performance consistency across both domains, then boilerpipe performs best. Performance aside, its codebase is seems to be quite stable and it works really fast.

Introducing Apache Mahout – calable, commercial-friendly machine learning for building intelligent applications

Brent Sordyl — Wed, 31 Aug 2011 13:55:15 +0000

Summary: Once the exclusive domain of academics and corporations with large research budgets, intelligent applications that learn from data and user input are becoming more common. The need for machine-learning techniques like clustering, collaborative filtering, and categorization has never been greater, be it for finding commonalities among large groups of people or automatically tagging large volumes of Web content. The Apache Mahout project aims to make building intelligent applications easier and faster. Mahout co-founder Grant Ingersoll introduces the basic concepts of machine learning and then demonstrates how to use Mahout to cluster documents, make recommendations, and organize content.
