title: Experiments in cross-domain few-shot learning for image classification: extended abstract

authors: Wang, Hongyu

subjects: computer science

abstract: We summarise experiments (Wang et al., 2022) evaluating cross-domain few-shot learning (CDFSL) with feature extractors trained on ImageNet. The work explores the transfer performance of extracted features on five target domains with different degrees of similarity to ImageNet. These experiments compare robust classifiers and normalisation methods, consider multi-instance learning algorithms, and evaluate the effect of using features extracted by different ResNet backbones at various levels of their convolutional hierarchies. The cosine similarity classifier and 1-vs-rest logistic regression with ℓ2 regularisation are the top-performing robust classifiers in the evaluation, and ℓ2 normalisation improves performance on all five target domains when using LDA as the robust classifier. The results also show that feature extractors with the highest capacity do not always achieve the best CDFSL performance. Lastly, simple multi-instance learning methods are shown to improve classifier accuracy.

title: Biochemical characterization of an active pyrophosphate-dependent phosphofructokinase from Treponema pallidum

authors: Roberson, Russell S.

subjects: syphilis

abstract: An active pyrophosphate-dependent phosphofructokinase containing a six residue polyhistidine tag has been cloned from Treponema pallidum, and characterized biochemically. The phosphofructokinase has pH optima for activity of 8.0 for both the forward and reverse reactions. The apparent Km for pyrophosphate was 0.042 mM (Vmax of 141 U mg−1 protein) and for fructose-6-phosphate, 0.529 mM. The apparent Km for the reverse reaction for fructose-1,6-diphosphate was 0.267 mM (Vmax of 42.4 U mg−1 protein). The enzyme appears to be both a dimer and non-allosteric.

title: Mā Te Wai - Ka Piki Ake Te Hauora

authors: Rollo, Te Manaaroha Pirihira

abstract: This paper researched traditional Māori forms of music therapy focusing on waiata¹ and taonga pūoro² . Linking cultures: collaborative partnerships in music therapy and related disciplines is the main objective of this research. In support, this paper examined past and current Māori practices that aim to heal and promote ‘well-being’ amongst people, thus resulting in linking the Māori culture and therapeutic values and practices in contemporary New Zealand
