title: Using weighted nearest neighbor to benefit from unlabeled data

authors: Driessens, Kurt

subjects: computer science

abstract: The development of data-mining applications such as textclassification and molecular profiling has shown the need for machine learning algorithms that can benefit from both labeled and unlabeled data, where often the unlabeled examples greatly outnumber the labeled examples. In this paper we present a two-stage classifier that improves its predictive accuracy by making use of the available unlabeled data. It uses a weighted nearest neighbor classification algorithm using the combined example-sets as a knowledge base. The examples from the unlabeled set are “pre-labeled” by an initial classifier that is build using the limited available training data. By choosing appropriate weights for this pre-labeled data, the nearest neighbor classifier consistently improves on the original classifier.

title: Diversity or Perversity? Investigating Queer Narratives, Resistance, and Representation in Aotearoa / New Zealand, 1948-2000

authors: Burke, Christopher J. F.

subjects: queer

abstract: This thesis contributes to the burgeoning field of the history of sexuality in New Zealand and seeks to distill the more theorised and reflexive understanding of the subjectively understood queer male identity since 1948. 

Emerging from the disciplines of History and English, this project draws from a range of narratological materials: parliamentary debates contained in Hansard, and novels and short stories written by men with publicly avowed queer identities. 

This thesis explores how both 'normative' identity and the category of 'the homosexual' were constructed and mobilised in the public domain, in this case, the House of Representatives. It shows that members of the House have engaged with an extensive tradition of defining and excluding; a process by which state and public discourses have constructed largely unified, negative and othering narratives of 'the homosexual'. This constitutes an overarching narrative of queer experience which, until the mid-1990s, excluded queer subjects from its construction. 

At the same time, fictional narratives offer an adjacent body of knowledge and thought for queer men and women. This thesis posits literature's position as an important and productive space for queer resistance and critique. Such texts typically engage with and subvert 'dominant' or 'normative' understandings of sexuality and disturb efforts to apprehend precise or linear histories of 'gay liberation' and 'gay consciousness'. 

Drawing from the works of Frank Sargeson, James Courage, Bill Pearson, Noel Virtue, Stevan Eldred-Grigg, and Peter Wells, this thesis argues for a revaluing of fictional narratives as active texts from which historians can construct a matrix of cultural experience, while allowing for, and explaining, the determining role such narratives play in the discursively constructed understandings of gender and sexuality in New Zealand.

title: End-user informed demographic projections for Hamilton up to 2041

authors: Cameron, Michael Patrick

subjects: cohort component model

abstract: This report provides a set of projections of the population of Hamilton City and the larger Hamilton Zone. The projections have been calculated by means of the cohort component model. The projections can be considered alongside official Statistics New Zealand projections, but differ from the latter in terms of assumptions made about net migration. These assumptions constitute a number of scenarios that were informed by the Hamilton City Council and local consultations. These scenarios are linked to the potential impact of a number of economic development activities. The report also contains projections of the number of households, the labour force and two ethnic groups: Māori and New Zealand Europeans. In addition, a dwellings-based methodology is used to produce small area (Census Area Unit) projections. Across the scenarios, Hamilton City’s projected population growth over the next two decades ranges from 13.8 percent to 36.0 percent. This is between 1.5 to 12.2 percentage points higher than the corresponding projected national growth.
