## PEBLS: Parallel Exemplar-Based Learning System

areas/learning/systems/pebls/

PEBLS (Parallel Exemplar-Based Learning System) is a nearest-neighbor learning system designed for applications where the instances have symbolic feature values. PEBLS has been applied to the prediction of protein secondary structure and to the identification of DNA promoter sequences. PEBLS incorporates a number of features intended to support flexible experimentation in symbolic domains. We have provided support for k-nearest neighbor learning, and the ability to choose among different techniques for weighting both exemplars and individual features. A number of post-processing techniques specific to the domain of protein secondary structure have also been provided.
