Improving Error Detection in Deep Learning Based Radiotherapy Autocontouring Using Bayesian Uncertainty
No full textBayesian Neural Nets (BNN) are increasingly used for robust organ auto-contouring. Uncertainty heatmaps extracted from BNNs have been shown to correspond to inaccurate regions. To help speed up the mandatory quality assessment (QA) of contours in radiotherapy, these heatmaps could be used as stimuli to direct visual attention of clinicians to potential inaccuracies. In practice, this is non-trivial to achieve since many accurate regions also exhibit uncertainty. To influence the output uncertainty of a BNN, we propose a modified accuracy-versus-uncertainty (AvU) metric as an additional objective during model training that penalizes both accurate regions exhibiting uncertainty as well as inaccurate regions exhibiting certainty. For evaluation, we use an uncertainty-ROC curve that can help differentiate between Bayesian models by comparing the probability of uncertainty in inaccurate versus accurate regions. We train and evaluate a FlipOut BNN model on the MICCAI2015 Head and Neck Segmentation challenge dataset and on the DeepMind-TCIA dataset, and observed an increase in the AUC of uncertainty-ROC curves by 5.6% and 5.9%, respectively, when using the AvU objective. The AvU objective primarily reduced false positives regions (uncertain and accurate), drawing less visual attention to these regions, thereby potentially improving the speed of error detection.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Computer Graphics and VisualisationPattern Recognition and Bioinformatic

An Analysis of the CHC Model for Comparing Cognitive Architectures
No full textAbstractThere are many cognitive architectures available nowadays, and each architecture has its own different mechanisms. Therefore, we need to identify the advantages and disadvantages of these architectures in order to improve upon them. In this paper, we propose new metrics for comparing cognitive architectures based on the Cattell-Horn-Carroll (CHC) model, which is used in psychology to explain factors of intelligence. Here, we analyze factors of intelligence in the CHC model and interpret them as elements of a new cognitive architecture. Then, the CHC model is investigated with respect to “data” and “processing” to obtain a metric for each component. We present examples using Soar and LIDA to illustrate comparing different cognitive architectures and demonstrate the effectiveness of our approach
(Urticaceae)
No full textLaportea bulbifera (Ulticaceae) is a monoecious plant that has a unique sexual expression: female flowers form on the upper part and male flowers on the lower part on an individual shoot. Therefore, for the seed reproduction, pollen needs to be transferred from the lower (male) to the upper (female) flowers. Our observations of male flowers confirmed that pollen was dispersed upward by explosive wind pollination. A male flower has five stamens, and when the petals are open, the stamens are caught in a pistillode. With the growth of the stamens, they are released from the pistillode and then straightened with a spring-like movement of the filament. At the same time, the anthers dehisce, and the pollen is dispersed. The explosive release of pollen from the anthers and light wind in the habitat (forest edge or gap) contributes to wind pollination in L. bulbifera

Mantis Shrimp Capture Technique.m4v
No full textThis short video was taken by Diarmaid Ó Foighil in the Indian River Lagoon (Florida) and it demonstrates the bait-and-capture technique (Goto et al., 2018) used by first author Teal Harrison* to collect Lysiosquilla scabricauda specimens. A bait fish was placed directly over a submerged host mantis shrimp burrow opening and once a resident emerged, its raptorial appendages were sequentially grasped by hand and, as it tired, the specimen was slowly pulled upward out of its burrow.*Teal A.

「俳句」単元の計画の作成とその授業研究実践報告 : 野口雨情の韻文指導観をもとに
No full textIn Taisho period, Noguchi Ujo, the author of children's songs, and Awano Ryutaro, elementary school teacher, encouraged the merit of the verses which were written without contemplation. Because they thought that children's mind could be expressed in an instant. I tried to apply it to National collage of technology education. The students in the school are 15-18 years old, not so little age. But, generally, it is said that recently teenagers become younger in spirit. So I think teachers should understand them deeply and should help them. This time, I tried to analyze haikus, one of verses, written by students and guess their mind and life. Then it has been shown that the verses written without contemplation have merit to understand students' mind though it is not so artistic.現代社会文化研究 別冊「現代社会文化研究科プロジェクト報告書
