The Entropic Associative Memory is a novel computational model of memory that uses a standard array or table as its medium. The system defines three memory operations in relation to a cue, which are called λ-register, η-recognition and β-retrieval. The memory is declarative, abstractive, distributed, productive, constructive and cues not included i...
The Entropic Associative Memory (EAM) holds declarative but distributed representations of remembered objects. These are characterized as functions from features to discrete values in an abstract amodal space. Memory objects are registered or remembered through a declarative operation; memory recognition is defined as a logical test and cues of obj...
Manuscript symbols can be stored, recognized and retrieved from an entropic digital memory that is associative and distributed but yet declarative; memory retrieval is a constructive operation, memory cues to objects not contained in the memory are rejected directly without search, and memory operations can be performed through parallel computation...

Natural memories are associative, declarative and distributed, and memory retrieval is a constructive operation. In addition, cues of objects that are not contained in the memory are rejected directly. Symbolic computing memories resemble natural memories in their declarative character, and information can be stored and recovered explicitly; howeve...
Natural memories are associative, declarative and distributed. Symbolic computing memories resemble natural memories in their declarative character, and information can be stored and recovered explicitly; however, they lack the associative and distributed properties of natural memories. Sub-symbolic memories developed within the connectionist or ar...

The general interest in learning objects have decayed in the last ten years. This approach to produce, organise, and manage educational content set off to model any educational content as a collection of one or more learning object, yet it could barely go beyond an extremely basic conception of learning objects that did not distinguish them from ot...
We developed a proposal of a usability evaluation by the experts of a learning management system (LMS). The instrument is designed on the basis of the general criteria for the heuristic evaluation proposed by Nielsen, as well as on international standards, guides, and recommendations for software quality (ISO 9241 and ISO 9126). We present the resu...

Mainstream distance learning nowadays is heavily influenced by traditional educational approaches that produces homogenised learning scenarios for all learners through learning management systems. Any differentiation between learners and personalisation of their learning scenarios is left to the teacher, who gets minimum support from the system in...
It is believed that, with the help of suitable technology, learners and systems can cooperate in building a sufficiently accurate learner model they can use to promote learner reflection through discussion of their knowledge, preferences and motivational dispositions (among other learner characteristics). Open learner modelling is a technology that...

Opening a model of the learner is a potentially complex operation. There are many aspects of the learner that can be modelled, and many of these aspects may need to be opened in different ways. In addition, there may be complicated interactions between these aspects which raise questions both about the accuracy of the underlying model and the metho...
We analyse how a learner modelling engine that uses belief functions for evidence and belief representation, called xLM, reacts to different input information about the learner in terms of changes in the state of its beliefs and the decisions
that it derives from them. The paper covers xLM induction of evidence with different strengths from the qua...
This paper describes the design of the learner modelling component of the LeActiveMath system, which was conceived to integrate modelling of learners’ competencies in a subject domain, motivational and affective
dispositions and meta-cognition. This goal has been achieved by organising learner models as stacks, with the subject domain
as ground lay...
We describe XLM, the learner modelling subsystem of LEACTIVE- MATH, from the viewpoint of how it makes use of technologies associated with the Semantic Web. We discuss how a better usage of these technologies could make of XLM a more generic learner modelling engine to serve a variety of e- learning systems. We try to foresee important issues to be...

An important trend in the development of intelligent tutoring systems (ITS) has been that of integrating characteristics proper of human tutoring into their performance, with the aim of providing the student with a more personalized and friendly environment for learning according to his traits and progress. These characteristics may give the studen...
Intelligent Tutoring Systems represent a successful enterprise of Artificial Intelligence (AI) and they have demonstrated to be useful on delimited domains [1]. However, in many of these programs, the tutor-student interaction has been unnatural. In the last years, the research on human-computer interaction has tried to provide student-tutor intera...

We present results of using inductive logic programming (ILP) to produce learner models by behavioural cloning. Models obtained
using a program for supervised induction of production rules (ripper) are compared to models generated using a well-known
program for ILP (foil). It is shown that the models produced by foil are either too specific or too...
This paper describes a prototype of a learning management system we have developed following the Sharable Content Object Reference Model (SCORM) by the Advanced Distributed Learning Initiative. The system is able to deliver the learning objects composing a course either by following the organization defined in the course's manifesto, or by dynamica...
We report an empirical study on the application of machine learning to the modelling of novice Controllers' skills in balancing a pole (inverted pendulum) on top of a cart. Results are presented on the predictive power of the models, and the extent to which they were tailored to each Controller. The behaviour of the participants in the study and th...
The educational benefits of involving learners as active players in the learner modelling process
have been an important motivation for research on this form of learner modelling, henceforth
referred to as participative learner modelling. Such benefits, conceived as the promotion of learners' reflection on and awareness of their own knowledge, have...
We discuss the implications of making learner models that can be inspected by learners within the context of a sensorimotor
control task—that of balancing a pole hinged to a cart. We argue that the requirement of producing models that are comprehensible
by learners limits the options of modelling strategy, constrains model structure and calls for f...
‘Participative learner modelling’ is characterised by the active and explicit participation of the learner in the modelling
task. This definition encompasses several kinds of learner modelling processes, since it does not impose additional restrictions
on the sort of the learner’s goals, beliefs, or actions. The learner’s participation can be of co...

Mathematical competitions tend to be very exclusive events, not because they are closed to everyone participation, but because few people really enjoy them. They usually take the shape of an individual/group assessment, where each participant/group works silently in isolation till they complete the test and hand it to the supervisor. Once all parti...
