title: Energy cultures: Implication for policymakers

authors: Barton, Barry

abstract: The Energy Cultures research project (2009-2012) was planned to help inform policy making related to residential energy use and energy efficiency in New Zealand. It sought, in part, to help address the difficulties faced by government agencies in achieving the economically viable potential for residential electricity savings. In particular, the project set out to examine household energy behaviour in relation to space heating and hot water heating, which together account for around 60% of household energy use. The programme was designed as a number of discrete research projects, linked together by the Energy Cultures conceptual framework. This report presents the policy implications of the multiple findings of that research.

title: Algorithm selection on data streams

authors: van Rijn, Jan N.

subjects: Data Stream Mining

abstract: We explore the possibilities of meta-learning on data streams, in particular algorithm selection. In a first experiment we calculate the characteristics of a small sample of a data stream, and try to predict which classifier performs best on the entire stream. This yields promising results and interesting patterns. In a second experiment, we build a meta-classifier that predicts, based on measurable data characteristics in a window of the data stream, the best classifier for the next window. The results show that this meta-algorithm is very competitive with state of the art ensembles, such as OzaBag, OzaBoost and Leveraged Bagging. The results of all experiments are made publicly available in an online experiment database, for the purpose of verifiability, reproducibility and generalizability.

title: Legal, business and comparative issues in mining and petroleum activity with respect to Māori matters

authors: Barton, Barry

abstract: In this paper I propose to do three things: to identify the very different implications of the different stages of the mining and the oil and gas sequence, to discuss the basics of the Crown Minerals Act and associated legislation, with particular reference to Māori interests, and to touch on a few points of comparison with Canada.
