Highlights
Inteligência Artificial – Uma Abordagem de Aprendizado de Máquina
Winner of the Brazilian Jabuti Prize (the most important literary award in Brazil), the book Inteligência Artificial – Uma Abordagem de Aprendizado de Máquina addresses the main machine learning concepts and algorithms and points out ways to transform this knowledge into practical applications.
MDLText: An Efficient and Lightweight Text Classifier
MDLText is an efficient, lightweight, scalable, and fast multinomial text classifier. It exhibits fast incremental learning and is sufficiently robust to prevent overfitting, desirable features in real-world applications, large-scale problems, and online scenarios.
