  2. 1. Using Learning Analytics to Understand and Support Collaborative Learning

    Author : Mohammed Saqr; Uno Fors; Jalal Nouri; Barbara Wasson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Learning analytics; Social Network Analysis; Collaborative Learning; Medical Education; Interaction Analysis; Machine Learning; Information Society; informationssamhället;

    Abstract : Learning analytics (LA) is a rapidly evolving research discipline that uses insights generated from data analysis to support learners and optimize both the learning process and learning environment. LA is driven by the availability of massive data records regarding learners, the revolutionary development of big data methods, cheaper and faster hardware, and the successful implementation of analytics in other domains.

  4. 2. Learning of Timed Systems

    Author : Olga Grinchtein; Bengt Jonsson; Oded Maler; Uppsala universitet; []
    Keywords : learning regular languages; timed systems; event-recording automata;

    Abstract : Regular inference is a research direction in machine learning. The goal of regular inference is to construct a representation of a regular language in the form of deterministic finite automaton (DFA) based on the set of positive and negative examples. READ MORE

  5. 3. Engineering Competitive and Query-Optimal Minimal-Adaptive Randomized Group Testing Strategies

    Author : Muhammad Azam Sheikh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; learning by queries; combinatorial search; competitive ratio; randomization; pooling design; group testing; linear program;

    Abstract : Suppose that given is a collection of $n$ elements where $d$ of them are \emph{defective}. We can query an arbitrarily chosen subset of elements which returns Yes if the subset contains at least one defective and No if the subset is free of defectives. The problem of group testing is to identify the defectives with a minimum number of such queries. READ MORE

  6. 4. Perspectives on Probabilistic Graphical Models

    Author : Dong Liu; Ragnar Thobaben; Harri Lähdesmäki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bayesian methods; graphical models; inference; learning; statistics; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Probabilistic graphical models provide a natural framework for the representation of complex systems and offer straightforward abstraction for the interactions within the systems. Reasoning with help of probabilistic graphical models allows us to answer inference queries with uncertainty following the framework of probability theory. READ MORE

  7. 5. Medical and nurse students' perspective on learning in acute care

    Author : Ann Hägg Martinell; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Background: Medical and nurse students’ professional training takes place in a complex and rapidly changing health care setting. Workplace learning in this context have a considerable potential to contribute to the development of professional competence. However, the complexity of the acute care context can also hinder such an advancement. READ MORE
