Machine Learning for Protein Subcellular Localization Prediction

by Shibiao Wan, Man-Wai Mak

Overview

Comprehensively covers protein subcellular localization from single-label prediction to multi-label prediction, and includes prediction strategies for virus, plant, and eukaryote species. Three machine learning tools are introduced to improve classification refinement, feature extraction, and dimensionality reduction.
