title: Locally weighted naive Bayes

authors: Frank, Eibe

subjects: computer science

abstract: Despite its simplicity, the naive Bayes classifier has surprised machine learning researchers by exhibiting good performance on a variety of learning problems. Encouraged by these results, researchers have looked to overcome naive Bayes' primary weakness—attribute independence—and improve the performance of the algorithm. This paper presents a locally weighted version of naive Bayes that relaxes the independence assumption by learning local models at prediction time. Experimental results show that locally weighted naive Bayes rarely degrades accuracy compared to standard naive Bayes and, in many cases, improves accuracy dramatically. The main advantage of this method compared to other techniques for enhancing naive Bayes is its conceptual and computational simplicity.

title: An investigation into pedagogical challenges facing international tertiary-level students in New Zealand

authors: Johnson, E. Marcia

subjects: academic literacy

abstract: Since the late 1990s, the overall number of international students studying at tertiary level in New Zealand has increased over 400% and, although enrolments have declined recently, there are still significant numbers of overseas students. This situation has brought continuing pedagogical challenges for tertiary teachers and students. The main purposes of this case study project were to uncover what was occurring within classrooms at one New Zealand university, what types of language and instructional styles were being used by lecturers, and which aspects of degree study international students found most difficult. It was anticipated that through developing a better understanding of key factors interacting with students' emerging academic literacy, improvements to educational practices in our multicultural, multilingual program could be established.

title: Re-creating legal space for the first law of Aotearoa-New Zealand

authors: Joseph, Robert

subjects: law

abstract: Some of the historic and contemporary statutory and case law examples of a hybrid Maori-British common law legal system in Aotearoa-New Zealand are discussed. The importance and role performed by the First Law, the tikanga Maori customary law is highlighted.
