title: Multi-label classification using boolean matrix decomposition

authors: Wicker, Jörg

subjects: Machine learning

abstract: This paper introduces a new multi-label classifier based on Boolean matrix decomposition. Boolean matrix decomposition is used to extract, from the full label matrix, latent labels representing useful Boolean combinations of the original labels. Base level models predict latent labels, which are subsequently transformed into the actual labels by Boolean matrix multiplication with the second matrix from the decomposition. The new method is tested on six publicly available datasets with varying numbers of labels. The experimental evaluation shows that the new method works particularly well on datasets with a large number of labels and strong dependencies among them.

title: CSCW in New Zealand: a snapshot

authors: Blackett, Colin

subjects: Computer Science

abstract: This report has been produced as one of the outputs of the FORST funded project "Improved Computer Supported Collaborative Work Systems" which is currently running in the Department of Computer Science at the University of Waikato. Its aim is to give a snapshot of the uses of and possibilities for Computer Supported Collaborative (also Co-operative) Work (also Working) (CSCW) within New Zealand.

title: Reclaiming Kaitiakitanga : An intergenerational perspective of Kaitiakitanga within Te Parawhau

authors: Walker, Erana

subjects: Kaitiakitanga

abstract: Kaitiakitanga is a concept that is utilised widely throughout the Māori world for the protection and preservation of cultural aspects to Māori. Through years of application by westernised mainstream processes the value has largely been restricted to the realms of environmental protection. This restriction has often been the result of misinterpretation of Kaitiakitanga and its relevance as a concept to Māori. The purpose of the thesis is to question how the perspective of Kaitiakitanga is constructed in the minds of representatives from the hapū of Te Parawhau. To test for variance, the research spans across two generations of hapū members. Using Whakawhiti Kōrero for data collection as well as Kaupapa Māori methodology as guidance, the thesis explores perspectives of two generations of Te Parawhau descendants around Kaitiakitanga and how it can be developed to aid in the growth and prosperity of the hapū. Key themes highlighted by the analysis encompass ideas of connectedness as well as spiritual, physical, environmental and human elements of responsibility and obligation. The thesis introduces a distinct Te Parawhau analytical framework for its analysis of rich kōrero by hapū members in relation to Kaitiakitanga. Through this framework the value of Kaitiakitanga is tested for relevance to Te Parawhau and its future development. The world view of Te Parawhau has formed the basis of participant perspectives around Kaitiakitanga and leads the researcher to consider that such knowledge is important to the future functionality of Māori value’s. The thesis concludes to show that there are indeed differences in application and perspectives of Kaitiakitanga within the hapū of Te Parawhau.
