1. Abstraction in artificial intelligence and complex systems.

Author

Saitta, Lorenza and Zucker, Jean-Daniel

Subjects
Abstraction, Artificial intelligence -- Philosophy
Abstract

Summary: Abstraction is a fundamental mechanism underlying both human and artificial perception, representation of knowledge, reasoning and learning. This mechanism plays a crucial role in many disciplines, notably Computer Programming, Natural and Artificial Vision, Complex Systems, Artificial Intelligence and Machine Learning, Art, and Cognitive Sciences. This book first provides the reader with an overview of the notions of abstraction proposed in various disciplines by comparing both commonalities and differences. After discussing the characterizing properties of abstraction, a formal model, the KRA model, is presented to capture them. This model makes the notion of abstraction easily applicable by means of the introduction of a set of abstraction operators and abstraction patterns, reusable across different domains and applications. It is the impact of abstraction in Artificial Intelligence, Complex Systems and Machine Learning which creates the core of the book. A general framework, based on the KRA model, is presented, and its pragmatic power is illustrated with three case studies: Model-based diagnosis, Cartographic Generalization, and learning Hierarchical Hidden Markov Models.

2. Phase transitions in machine learning.

Author

Saitta, Lorenza, Cornuejols, Antoine, and Giordana, Attilio

Subjects
Machine learning, Phase transformations (Statistical physics)
Abstract

Summary: "Phase transitions typically occur in combinatorial computational problems and have important consequences, especially with the current spread of statistical relational learning and as sequence learning methodologies. In Phase Transitions in Machine Learning the authors begin by describing in detail this phenomenon and the extensive experimental investigation that supports its presence. They then turn their attention to the possible implications and explore appropriate methods for tackling them"-- Provided by publisher.

18. Modelling Physics Knowledge Acquisition in Children with Machine Learning

Author

Neri, Filippo, Saitta, Lorenza, and Tiberghien, Andree

Abstract

A computational approach to the simulation of cognitive modelling of children learning elementary physics is presented. Goal of the simulation is to support the cognitive scientist's investigation of learning in humans. The Machine Learning system WHY , able to handle domain knowledge (including a causal model of the domain), has been chosen as tool for the simulation of the cognitive development. In this paper the focus will be on knowledge representation schemes, useful to support further modelling of conceptual change.
