title: Truth vanishes again: deflationism, assertion, and 'presenting as true'

authors: Wyatt, Jeremy

abstract: In this talk, I'll aim to defend deflationism about the concept of truth from a prominent objection. The objection, due to Dorit Bar-On and Keith Simmons, is that deflationists cannot account for the fact that asserting a proposition involves presenting the proposition as being true. In responding to this objection, I will focus on the influential minimalist account of the concept of truth that has been developed by Paul Horwich. I will motivate an account of ‘presenting as true’ that has been recently proposed by Neri Marsili and then explain why it is fully compatible with minimalism.

title: Better Self-training for Image Classification Through Self-supervision

authors: Sahito, Attaullah

subjects: Science & Technology

abstract: Self-training is a simple semi-supervised learning approach: Unlabelled examples that attract high-confidence predictions are labelled with their predictions and added to the training set, with this process being repeated multiple times. Recently, self-supervision—learning without manual supervision by solving an automatically-generated pretext task—has gained prominence in deep learning. This paper investigates three different ways of incorporating self-supervision into self-training to improve accuracy in image classification: self-supervision as pretraining only, self-supervision performed exclusively in the first iteration of self-training, and self-supervision added to every iteration of self-training. Empirical results on the SVHN, CIFAR-10, and PlantVillage datasets, using both training from scratch, and Imagenet-pretrained weights, show that applying self-supervision only in the first iteration of self-training can greatly improve accuracy, for a modest increase in computation time.

title: Poi Apakura

authors: Maxwell, Te Kahautu

abstract: Poi Apakura portrays the battles both pre European contact through to the land wars and the confiscation of 400,000 acres of Te Whakatōhea land s in 1865 with the killing of the missionary Rev Catl Volkner known as Te Wākana. Performed by Ōpōtiki Mai Tawhiti at the Te Matatini World Championship Kapa Haa Competition 2013.
