title: Random model trees: an effective and scalable regression method

authors: Pfahringer, Bernhard

subjects: computer science

abstract: We present and investigate ensembles of randomized model trees as a novel regression method. Such ensembles combine the scalability of tree-based methods with predictive performance rivaling the state of the art in numeric prediction. An extensive empirical investigation shows that Random Model Trees produce predictive performance which is competitive with state-of-the-art methods like Gaussian Processes Regression or Additive Groves of Regression Trees. The training
and optimization of Random Model Trees scales better than Gaussian Processes Regression to larger datasets, and enjoys a constant advantage over Additive Groves of the order of one to two orders of magnitude.

title: Waiata anthems: How Aotearoa (New Zealand) popular and contemporary music is addressing generational trauma and revitalising te reo Māori (the Māori language)

authors: Walker, Alroy

abstract: Waiata is translated as song or chant from te reo Māori (the Māori language), yet it has many forms and important functions in te ao Māori (the Māori world). Waiata is most commonly experienced publicly in Aotearoa in support of whaikõrero (oration, formal speech-making), but it also serves to reinforce Māori interconnectedness to others, the natural world and to the supernatural world. Enduring from pre-encounter oral culture, waiata serve as vessels and a mode of transmission for mātauranga Māori (Māori knowledge), histories (whanau, iwi) and culture. This presentation focuses on emergent and contemporary modes of waiata (punk, hardcore and indie) in a post-colonial context, examining musician motivations, the role that music plays in the revitalisation of te reo Māori, and how it honours the purpose of waiata tawhito (traditional waiata). The project is part of ongoing research supported by the partnership agreement between Prifysgol Caerdydd and University of Waikato.
