title: A review of multi-instance learning assumptions

authors: Foulds, James Richard

subjects: computer science

abstract: Multi-instance (MI) learning is a variant of inductive machine learning, where each learning example contains a bag of instances instead of a single feature vector. The term commonly refers to the supervised setting, where each bag is associated with a label. This type of representation is a natural fit for a number of real-world learning scenarios, including drug activity prediction and image classification, hence many MI learning algorithms have been proposed. Any MI learning method must relate instances to bag-level class labels, but many types of relationships between instances and class labels are possible. Although all early work in MI learning assumes a specific MI concept class known to be appropriate for a drug activity prediction domain; this ‘standard MI assumption’ is not guaranteed to hold in other domains. Much of the recent work in MI learning has concentrated on a relaxed view of the MI problem, where the standard MI assumption is dropped, and alternative assumptions are considered instead. However, often it is not clearly stated what particular assumption is used and how it relates to other assumptions that have been proposed. In this paper, we aim to clarify the use of alternative MI assumptions by reviewing the work done in this area.

title: Impacts on sediment transport of proposed expansion of the Port of Tauranga shipping channels and wharves

authors: Mullarney, Julia C.

abstract: We report results of an examination of the effects of proposed dredge-channel and wharf extensions in the Port of Tauranga (Figure 1). In previous work, we undertook a calibration and validation of a hydrodynamic model for Tauranga Harbour. The work used the hydrodynamic package Delft3D in depth-averaged mode (see Mullarney and de Lange, 2018, for details). The effects of the proposed developments on the hydrodynamics within the Harbour were examined and compared to flows with present-day bathymetry and wharf configurations.

title: A newly-available resource for historians of early New Zealand: The Marist Missionary Letters (1838-54)

authors: Jennings, William

abstract: The 7000 pages of primary documents of the Lettres reçues d’Océanie constitute a vast new source for the study of the Pacific during the period 1838-54. Published in 2009 after sixteen years of transcription, the Lettres are the collected correspondence of the first French Marist missionaries to New Zealand and other Pacific islands. In the words of Pacific historian Hugh Laracy, they are ‘the single most important foundational contribution to Pacific history in its fullest extent since J. C. Beaglehole’s magisterial editions of James Cook’s Journals. About 2000 of those pages are transcripts of letters written in New Zealand that open up a fresh perspective of life before the wars of the 1860’s. This paper will locate the early French Marist Māori mission within the context of New Zealand public history before exploring how the Lettres reçues d’Océanie can complement existing views of early colonial New Zealand. To better contextualise the correspondence, it would be useful to begin with a brief background of the Marists’ presence in New Zealand.
