Learnability, representation, and language : a Bayesian approach
… human cognition means understanding learnability not only what (and how) the brain learns, but also what data is available to it from the world. Ideal learnability arguments seek to characterize what knowledge is in theory possible for an ideal reasoner to acquire, which illuminates …

On the Learnability of General Reinforcement-Learning Objectives
… known as probably approximately correct (PAC) -learnability. However, reward functions often serve as imperfect surrogates for true objectives, leading to reward hacking and undermining these guarantees. This thesis formalizes the specification and learnability of general reinforcement-learning …

Usability and learnability improvements for the TaleBlazer game editor
… especially essential to maximizing usability and learnability. This thesis presents a new version of the editor with improved front-end design and a new tutorials system. The updated implementation is intuitive, powerful, and user-friendly for both novice and experienced TaleBlazer users.

Cross-Linguistic Influences on English Loanword Learnability in the Japanese Context
This study was an investigation into the aural and written receptive knowledge of the English semantics of English lexis that is loanwords in the Japanese language and the predictive strength of the variables of semantic distance, concreteness/abstractness, polysemy, phonological distance, number …

On the Learnability of Disjunctive Normal Form Formulas and Decision Trees
The learnability of disjunctive normal form formulas and decision trees is investigated. Polynomial time algorithms are given, and nonlearnability results are obtained, for restricted versions of these general learning problems.

Improving learnability of high functionality user interfaces through simplification without loss of functionality
… tutorials will dramatically increase the learnability of Justify, and thus also increase user retention and satisfaction. User testing indicated that these changes in Justify made it easier to learn and more enjoyable to use, when compared to both the older version of Justify and to …

Investigating how the morphology of a robot arm affects the learnability of aimed throwing
… between the hand design on a robot arm and the learnability of aimed throwing. Aimed throwing is selected as the task because of its importance as a milestone in human evolution, as well as being a task with an unambiguous outcome. The process of designing and building the arm, in addition to …

The Pragmatic Strategy of Main-Clause Omission in Japanese: Its Contrast with Hebrew, and Its Learnability
<p>Typically, linguists study things that people actually say, but this dissertation focuses on what people do NOT say; specifically, it deals with main-clause omission. This paper presents an empirical study on main-clause omission constraints in Japanese after the concessive particle <em>ga</em> …

Anti-Unification in Constraint Logics: Foundations and Applications to Learnability in First-Order Logic, to Speed-Up Learning, and to Deduction
Unification is central to automated reasoning. Unification comes in a variety of forms, all of which compute (roughly stated) the greatest lower bound, or all maximal lower bounds, of any two or more syntactic objects in a partially-ordered set of such objects. The dual of unification is an …

Topics in computational learning theory and graph algorithms
… concepts is a sufficient condition for the PAC-learnability of that class. (An Occam algorithm is a randomized polynomial-time algorithm that, when given as input a sample of strings of some unknown concept to be learned, outputs a small description of a concept that is consistent with the …

Information-Theoretic Algorithms and Identifiability for Causal Graph Discovery
… us to show how Entropic Causal Inference permits learnability of causal graphs with particular information-theoretically simple structure. We show the first theoretical guarantee for finite-sample learnability with Entropic Causal Inference for pairs of random variables. Later, we extend this …

Unsupervised learning of lexical subclasses from phonotactics
… this sublexical analysis is challenged by a learnability problem: the sublexical membership of words is not directly observable. This study applies a state-of-the-art clustering method (a Dirichlet process mixture model) to a substantial number of Japanese and English words extracted from …

Towards a theory for the emergence of grid and place cell codes
… a network to simultaneously possess online learnability and high coding capacity. Because of this dynamical constraint in learning, a grid cell circuit has to be hardwired through some developmental process and cannot be easily modified by an experience-based synaptic rule without …

On efficient learning algorithms for neural networks.
… (PAC) learning model and we look for positive learnability results by restricting the distribution generating the training examples, the connectivity of the networks, and/or the weight values. This enables us to identify new classes of neural networks that are efficiently learnable in the …

Usability improvements for the TaleBlazer game editor
… to the TaleBlazer editor that improve the learnability, efficiency, and error correction ability for the game designer. These improvements consist of adding in an agent overview, a printable game summary, an error checker, and a redesign of the styling and layout of the previously existing …
