The Lab

The Algorithm Engineering and Machine Learning Laboratory (LEARN) is part of the Computer Science Department at the Pontifical Catholic University of Rio de Janeiro (PUC-Rio), in Brazil. LEARN expertise is on the design and implementation of efficient algorithms for advanced applications.

Our application focus is on

• Computational Linguistics
• and Computational Finance.

Among the applications developed at LEARN we have: Natural Language Processors, Automatic Traders, Pipeline Transportation Planners and Pipeline Network Supervisory System. Recently, we have been developing Machine Learning based Web Information Extractors. The know-how gathered at LEARN enabled the development of some advanced Machine Learning frameworks. The first one was used to generate a multi-agent system which got the third place on the Trading Agent Competition 2004. There is also another one for active and semi-supervised learning. This one generates text mining applications which are being used by important digital media companies.
