Combining Analytical and Evolutionary Inductive Programming

Neil Crossley, Emanuel Kitzelmann, Martin Hofmann, Ute Schmid
Analytical inductive programming and evolutionary in- ductive programming are two opposing strategies for learning recursive programs from incomplete specifica- tions such as input/output examples. Analytical induc- tive programming is data-driven, namely, the minimal recursive generalization over the...

A Comparative Approach to Understanding General Intelligence: Predicting Cognitive Performance in an Open-ended Dynamic Task

Christian Lebiere, Cleotilde Gonzalez, Walter Warwick
The evaluation of an AGI system can take many forms. There is a long tradition in Artificial Intelligence (AI) of competitions focused on key challenges. A similar, but less celebrated trend has emerged in computational cognitive modeling, that of model comparison. As with AI competitions, model comparisons...

AGI Preschool: A Framework for Evaluating Early-Stage Human-like AGIs

Ben Goertzel, Vladimir Bugaj
A class of environments for teaching and evaluating AGI systems is described, modeled loosely on preschools used for teaching human children and intended specifically for early-stage systems aimed at approaching human-level, human-inspired AGI through a process resembling human developmental psychology....

Understanding the Brain's Emergent Properties

Don Miner, Marc Pickett, Marie desJardins
In this paper, we discuss the possibility of applying rule abstraction, a method designed to understand emergent systems, to the physiology of the brain. Rule abstraction reduces complex systems into simpler subsystems, each of which are then understood in terms of their respective subsystems. This process...

The robotics path to AGI using Servo Stacks

J. Storrs Hall
The case is made that the path to AGI through cogni- tive and developmental robotics is compelling. Beyond the familiar argument that it keeps researchers honest by forcing their systems to cope with the real world, it encourages them to recapitulate the evolutionary de- velopmental path which gave rise...

Feature Dynamic Bayesian Networks

Marcus Hutter
Feature Markov Decision Processes (MDPs) [Hut09] are well-suited for learning agents in general environments. Nevertheless, unstructured ()MDPs are limited to rela- tively simple environments. Structured MDPs like Dynamic Bayesian Networks (DBNs) are used for large-scale real- world problems. In this...

Distribution of Environments in Formal Measures of Intelligence

Bill Hibbard
This paper shows that a constraint on universal Turing machines is necessary for Legg's and Hutter's formal measure of intelligence to be unbiased. It also explores the relation of the No Free Lunch Theorem to formal measures of intelligence.

Incorporating Planning and Reasoning into a Self-Motivated, Communicative Agent

Daphne Liu, Lenhart Schubert
Most work on self-motivated agents has focused on ac- quiring utility-optimizing mappings from states to ac- tions. But such mappings do not allow for explicit, rea- soned anticipation and planned achievement of future states and rewards, based on symbolic knowledge about the environment and about the...

What Is Artificial General Intelligence? Clarifying The Goal For Engineering And Evaluation

Mark R. Waser
Artificial general intelligence (AGI) has no consensus definition but everyone believes that they will recognize it when it appears. Unfortunately, in reality, there is great debate over specific examples that range the gamut from exact human brain simulations to infinitely capable systems. Indeed, it...

Stimulus processing in autonomously active cognitive systems

Claudius Gros
The brain is autonomously active and possesses an on- going internal dynamics which continues even in the temporary absence of external sensory stimuli. New experimental evidences, and theoretical considerations, indicate that this eigendynamics plays a central role in regulating the overall cognitive...

Holistic Intelligence: Transversal Skills & Current Methodologies

Kristinn R. Thórisson, Eric Nivel
Certain necessary features of general intelligence are more system-wide than others; features such as attention, learning and temporal grounding are transversal in that they seem to affect a significant subset of all mental operation. We argue that such transversal features unavoidably impose fundamental...

A formal framework for the symbol grounding problem

Benjamin Johnston, Mary-Anne Williams
A great deal of contention can be found within the published literature on grounding and the symbol grounding problem, much of it motivated by appeals to intuition and unfalsifiable claims. We seek to define a formal framework of representa- tion grounding that is independent of any particular opinion,...

Consciousness in Human and Machine: A Theory and Some Falsifiable Predictions

Richard P. W. Loosemore
To solve the hard problem of consciousness we first note that all cognitive systems of sufficient power must get into difficulty when trying to analyze consciousness concepts, because the mechanism that does the analysis will bottom out in such a way that the system declares these concepts to be both...

CHS-Soar: Introducing Constrained Heuristic Search to the Soar Cognitive Architecture

Sean A. Bittle, Mark S. Fox
Cognitive architectures aspire for generality both in terms of problem solving and learning across a range of problems, yet to date few examples of domain independent learning has been demonstrated. In contrast, constraint programming often utilizes the same domain independent heuristics to find efficient...

A Unifying Framework for Analysis and Evaluation of Inductive Programming Systems

Martin Hofmann, Emanuel Kitzelmann, Ute Schmid
In this paper we present a comparison of several inductive programming (IP) systems. IP addresses the problem of learning (recursive) programs from incomplete specifications, such as input/output examples. First, we introduce condi- tional higher-order term rewriting as a common framework for inductive...

Unsupervised Segmentation of Audio Speech Using the Voting Experts Algorithm

Matthew Miller, Peter Wong, Alexander Stoytchev
Human beings have an apparently innate ability to seg- ment continuous audio speech into words, and that abil- ity is present in infants as young as 8 months old. This propensity towards audio segmentation seems to lay the groundwork for language learning. To artificially repro- duce this ability would...

Human and Machine Understanding Of Natural Language Character Strings

Peter G. Tripodes
There is a great deal of variability in the way in which different language users understand a given natural language (NL) character string. This variability probably arises because of some combination of differences in language users' perceptions of its context-of-use (pragmatics), identity and mode...
