Reflections on remixing open access content into open educational resources: A new paradigm for sustainable data-driven language learning systems design in higher education
(Springer, 2023)This chapter presents a new paradigm for sustainable data – driven language learning systems design in higher education that draws on qualitative reflections spanning a decade (2012–2022) with stakeholders from an ongoing ... -
Modelling a blockchain for smart contract verification using DeepSEA
(Association for Computing Machinery, 2022)To create trustworthy programs, the 'gold standard' is specifications at a high-enough level to clearly correspond to the informal specifications, and also a refinement proof linking these high-level specifications down ... -
Provably correct smart contracts: An approach using DeepSEA
(Association for Computing Machinery, 2022)It is possible to download a piece of software over the internet and then verify its correctness locally using an appropriate trusted proof system. However, on a blockchain like Ethereum, smart contracts cannot be altered ... -
Experiments in cross-domain few-shot learning for image classification: extended abstract
(PMLR, 2022)We summarise experiments (Wang et al., 2022) evaluating cross-domain few-shot learning (CDFSL) with feature extractors trained on ImageNet. The work explores the transfer performance of extracted features on five target ... -
Prevalence of sociodemographic factors in a cohort of diabetes mellitus: A retrospective study
(ACM, 2022)Exploring the sociodemographic factors of a cohort is a vital phase in revealing significant aspects of the societal health status. The health care sector utilises the results of exploratory analysis of the sociodemographic ... -
Showcasing the TAIAO project: providing resources for machine learning from images of New Zealand's natural environment
(Informa UK Limited, 2022)Proper management of the earth's natural resources is imperative to combat further degradation of the natural environment. However, the environmental datasets necessary for informed resource planning and conservation can ... -
Large scale K-means clustering using GPUs
(Springer Science and Business Media LLC, 2022)The k-means algorithm is widely used for clustering, compressing, and summarizing vector data. We present a fast and memory-efficient GPU-based algorithm for exact k-means, Asynchronous Selective Batched K-means (ASB ... -
Learning to extract geographic information from internet router hostnames
(ACM, 2021)Geolocating Internet routers is a long-standing and notoriously difficult challenge, and current solutions lack the accuracy and adaptability to yield reliable results. We revisit this problem, designing a solution capable ... -
Patient-reported diagnostic intervals to colorectal cancer diagnosis in the Midland region of New Zealand: a prospective cohort study
(Oxford University Press, 2021)Background and objectives New Zealand (NZ) has high rates of colorectal cancer (CRC) but low rates of early detection. The majority of CRC is diagnosed through general practice, where lengthy diagnostic intervals are ... -
Analyzing and repairing concept drift adaptation in data stream classification
(2021)Data collected over time often exhibit changes in distribution, or concept drift, caused by changes in factors relevant to the classification task, e.g. weather conditions. Incorporating all relevant factors into the model ... -
Surgical tool datasets for machine learning research: A survey
(Springer, 2022)This paper is a comprehensive survey of datasets for surgical tool detection and related surgical data science and machine learning techniques and algorithms. The survey offers a high level perspective of current research ... -
Evaluation of deep learning techniques on a novel hierarchical surgical tool dataset
(Springer Nature Switzerland AG, 2022)A new hierarchically organised dataset for artificial intelligence and machine learning research is presented, focusing on intelligent management of surgical tools. In addition to 360 surgical tool classes, we create a ... -
Children’s query formulation and search result exploration
(Springer Science and Business Media LLC, 2021)Our research aims at understanding children’s information search and their use of information search tools during educational pursuits. We conducted an observation study with 50 New Zealand school children between the ages ... -
A study of mobile app use for teaching and research in higher education
(Springer Science and Business Media LLC, 2022)The exponential growth in the use of digital technologies and the availability of mobile software applications (apps) has been well documented over the past decade. Literature on the integration of mobile technology into ... -
Mobile app development: Work-integrated learning collaborations with Māori and Fijian partners
(2022)Only a few information and communication technology (ICT) work-integrated learning (WIL) projects involving universities and Indigenous partners are being reported and very little is known about the approaches that are ... -
Physical metadata visualisation: The knitted personal library
(ACM, 2022)Personal collections, be they books, music, or artefacts have significance to the owner, and provide conversation and engagement with visitors. For example visitors of physical libraries may browse the spines, select a ... -
Efficiently correcting machine learning: considering the role of example ordering in human-in-the-loop training of image classification models
(ACM, 2022)Arguably the most popular application task in artificial intelligence is image classification using transfer learning. Transfer learning enables models pre-trained on general classes of images, available in large numbers, ... -
Action partnership research design: A new research methodology
(2022)Despite suggestions within LIS literature that users are active stakeholders in research, particularly in such areas as participatory design, examination of the findings indicates that this is not always the case. This is ... -
Typographic design in Māori-English bilingual picturebooks: some educational implications
(2022)The role of bilingual picturebooks in language learning has been explored recently by a number of authors who show their potential in normalising multilingualism (Naqvi, Thorne, Pfitscher, Nordstokke & McKeough, 2013; ... -
Transformers for multi-label classification of medical text: an empirical comparison
