Cooperative Research As a Strategy for University Teacher Training. A Case Study of Lesson and Learning Study
This paper presents the possibilities offered by Lesson and Learning Studies for training and for improving and generating knowledge by reconstructing the practical knowledge of teachers. Firstly, we provide a summary of the concept of practical knowledge and the tradition of teachers researching their own practice. This is followed by some principles of Lesson and Learning Studies, with examples of their possibilities for university teacher training taken from a case study of our own practice during a university master's degree

Optimising metadata workflows in a distributed information environment
The different purposes present within a distributed information environment create the potential for repositories to enhance their metadata by capitalising on the diversity of metadata available for any given object. This paper presents three conceptual reference models required to achieve this optimisation of metadata workflow: the ecology of repositories, the object lifecycle model, and the metadata lifecycle model. It suggests a methodology for developing the metadata lifecycle model, and illustrates how it might be used to enhance metadata within a network of repositories and services
A Boxology of Design Patterns for Hybrid Learning and Reasoning Systems
We propose a set of compositional design patterns to describe a large variety
of systems that combine statistical techniques from machine learning with
symbolic techniques from knowledge representation. As in other areas of
computer science (knowledge engineering, software engineering, ontology
engineering, process mining and others), such design patterns help to
systematize the literature, clarify which combinations of techniques serve
which purposes, and encourage re-use of software components. We have validated
our set of compositional design patterns against a large body of recent
literature.Comment: 12 pages,55 reference
Knowledge-Guided Data-Centric AI in Healthcare: Progress, Shortcomings, and Future Directions
The success of deep learning is largely due to the availability of large
amounts of training data that cover a wide range of examples of a particular
concept or meaning. In the field of medicine, having a diverse set of training
data on a particular disease can lead to the development of a model that is
able to accurately predict the disease. However, despite the potential
benefits, there have not been significant advances in image-based diagnosis due
to a lack of high-quality annotated data. This article highlights the
importance of using a data-centric approach to improve the quality of data
representations, particularly in cases where the available data is limited. To
address this "small-data" issue, we discuss four methods for generating and
aggregating training data: data augmentation, transfer learning, federated
learning, and GANs (generative adversarial networks). We also propose the use
of knowledge-guided GANs to incorporate domain knowledge in the training data
generation process. With the recent progress in large pre-trained language
models, we believe it is possible to acquire high-quality knowledge that can be
used to improve the effectiveness of knowledge-guided generative methods.Comment: 21 pages, 13 figures, 4 table
