title: Using model trees for classification

authors: Frank, Eibe

subjects: model trees

abstract: Model trees, which are a type of decision tree with linear regression functions at the leaves, form the basis of a recent successful technique for predicting continuous numeric values. They can be applied to classification problems by employing a standard method of transforming a classification problem into a problem of function approximation. Surprisingly, using this simple transformation the model tree inducer M5’, based on Quinlan’s M5, generates more accurate classifiers than the state-of-the-art decision tree learner C5.0, particularly when most of the attributes are numeric.

title: Late Miocene-Early Pliocene Matemateaonga Formation in eastern Taranaki Peninsula: A new 1:50,000 geological map and stratigraphic framework

authors: Vonk, Adam J.

subjects: Taranaki Basin

abstract: In recent years the Matemateaonga Formation has become an additional exploration play in Taranaki Basin. Exploration interest has been stimulated by the success of Swift Energy Company in the Rimu/Kauri prospect (38719), located near south Taranaki Coast. At this location, sandstone lithofacies, commonly termed “Manutahi Sandstone” in the lower parts of the Matemateaonga Formation have been intersected by the Kauri-A2 and Kauri-A3 wells at depths of ~1100-1200 m and are yielding commercial quantities of oil.
As part of a FRST-funded sedimentary basins research programme, we have geologically mapped in detail Matemateaonga Formation within an 1800 km2 area of the eastern peninsula region (Fig. 1), incorporating license areas 38739, 38718, 38753, 38138, 38139, 38141, 38140, 38716, 38758, 38728 and 38760. Mapping at 1:50,000 scale has revealed an ~1100 m-thick succession of cyclothemic, unconformity bounded shelfal strata of Late Miocene-Early Pliocene (Late Kapitean to Early Opoitian) age (c.5.5-4.7 Ma). This succession formed as a result of the interplay between climatically-driven 6th-order (41 k.y.) eustatic sea-level changes, high rates of basin subsidence and a substantial southerly-derived sediment flux. Individual sequences or groups of sequences are the fundamental mapping entities. The mapping area sits astride the southward-plunging Whangamomona Anticline, which has deformed the Late Neogene succession, producing a regional dip on its western flank of 2 to 4 degrees to the southwest. Northeast-southwest trending normal faults are relatively common and offset Matemateaonga Formation strata with throws of 2-50 m.
This improved knowledge of Matemateaonga Formation stratigraphy enhances the understanding of the distribution and geometry of potential reservoir sandstone units and associated mudstone seal units in the region.

title: How institutions frame mātauranga Māori (Commissioned by Waikato Regional Council)

authors: Whaanga, Hēmi

abstract: The primary questions for this report are:
1) How is Mātauranga Māori framed by Institutions?
2) How is Mātauranga Māori being operationalised by Institutions in New Zealand?
Mātauranga Māori is the intellectual capital generated by whānau, hapū and Iwi over multiple generations. It is a shared-community knowledge that is embedded in lived experience and carried in stories, song, place names, dance, ceremonies, genealogies, memories, visions, prophesies, teachings and original instructions, as and learnt through observation and copying of other community members.
It is a holistic system of orally passed knowledge, concepts, beliefs and practice. Mātauranga Māori, mātauranga ā-iwi, mātauranga ā-hapū, and mātauranga ā-whānau are dynamic, innovative, and generative systems of knowledge. Mātauranga Māori has been defined, framed, and operationalised with varying success by Institutions. Although the overall definitions vary somewhat, the general premise is that these government agencies acknowledge that mātauranga Māori is Māori-specific knowledge that is adaptive and regionally distinct. This recognition is important as it reinforces the notion that Māori are not a homogenous group, and that mātauranga Māori will differ across Iwi.
For the vast majority of institutions, improving their understanding of mātauranga Māori is an important strategic aim that can help guide their decision making, management, and monitoring procedures. Achieving this aim helps recognise the innovative potential of Māori knowledge, its contribution to council activities, and the usefulness of culturally appropriate data.
This report has identified seven factors that contribute towards a framework of understanding:
1) Acknowledging contemporary relevance and application: Iwi partners value mātauranga
Māori not only for its historic significance but its contemporary relevance in times of political change. Legislative requirements, iwi expectations, and a desire to build respectful relationships also contribute to current moves to understand and incorporate mātauranga Māori across regional council planning and decision-making activities.
2) Acknowledging cultural validity: Mātauranga Māori informs not only traditional practices but also Māori and iwi participation within Council activities.
3) Accepting epistemological difference: Eurocentric values and scientific disciplines tend to have primacy in a regional council context in part through historical tendencies and political representation. Mātauranga Māori brings a different value set and way of understanding phenomena to the table.
4) Acknowledging mana whenua responsibility for mātauranga Māori: The management and use of mātauranga represents a core responsibility of mana whenua. Relocating mātauranga and responsibility to act as a kaitiaki from a whānau, hapū or iwi to an institution, is a sensitive topic. Mātauranga is often vested with specific people (kaitiaki) or with local whānau and hapū to ensure the responsibilities for protecting the environment remain with those that live there.
5) Developing a more nuanced understanding of mātauranga Māori: Developing a more nuanced understanding of the different disciplines and content that exist under the broad definition of mātauranga Māori is necessary if Councils are to incorporate mātauranga Māori across a greater range of their work programmes.
