According to Clifford Geertz, the purpose of anthropology is not to explain culture but to explicate it. That should cause us to rethink our relationship with machine learning. It is, we contend, perfectly possible that machine learning algorithms, which are unable to explain, and could even be unexplainable themselves, can still be of critical use in a process of explication. Thus, we report on an experiment with anthropological AI. From a dataset of 175K Facebook comments, we trained a neural network (...) to predict the emoji reaction associated with a comment and asked a group of human players to compete against the machine. We show that a) the machine can reach the same accuracy as the players, b) it fails in roughly the same ways as the players, and c) easily predictable emoji reactions tend to reflect unambiguous situations where interpretation is easy. We therefore repurpose the failures of the neural network to point us to deeper and more ambiguous situations where interpretation is hard and explication becomes both necessary and interesting. We use this experiment as a point of departure for discussing how experiences from anthropology, and in particular the tension between formalist ethnoscience and interpretive thick description, might contribute to debates about explainable AI.

Making publics visible through digital traces has recently generated interest by practitioners of public engagement and scholars within the field of digital methods. This paper presents an experiment in moving such methods into critical proximity with political practice and discusses how digital visualizations of topical debates become appropriated by actors and hardwired into existing ecologies of publics and politics. Through an experiment in rendering a specific data-public visible, it shows how the interplay between diverse conceptions of the public as well (...) as the specific platforms and data invoked, resulted in a situated affordance-space that allowed specific renderings take shape, while disadvantaging others. Furthermore, it argues that several accepted tropes in the literatures of digital methods ended up being problematic guidelines in this space. Among these is the prescription to shown heterogeneity by pushing back at established media logics. (shrink)

Background: Although convolutional neural networks (CNNs) achieve high diagnostic accuracy for detecting Alzheimer’s disease (AD) dementia based on magnetic resonance imaging (MRI) scans, they are not yet applied in clinical routine. One important reason for this is a lack of model comprehensibility. Recently developed visualization methods for deriving CNN relevance maps may help to fill this gap as they allow the visualization of key input image features that drive the decision of the model. We investigated whether models with higher accuracy (...) also rely more on discriminative brain regions predefined by prior knowledge. Methods: We trained a CNN for the detection of AD in N = 663 T1-weighted MRI scans of patients with dementia and amnestic mild cognitive impairment (MCI) and verified the accuracy of the models via cross-validation and in three independent samples including in total N = 1655 cases. We evaluated the association of relevance scores and hippocampus volume to validate the clinical utility of this approach. To improve model comprehensibility, we implemented an interactive visualization of 3D CNN relevance maps, thereby allowing intuitive model inspection. Results: Across the three independent datasets, group separation showed high accuracy for AD dementia versus controls (AUC ≥ 0.91) and moderate accuracy for amnestic MCI versus controls (AUC ≈ 0.74). Relevance maps indicated that hippocampal atrophy was considered the most informative factor for AD detection, with additional contributions from atrophy in other cortical and subcortical regions. Relevance scores within the hippocampus were highly correlated with hippocampal volumes (Pearson’s r ≈ −0.86, p < 0.001). Conclusion: The relevance maps highlighted atrophy in regions that we had hypothesized a priori. This strengthens the comprehensibility of the CNN models, which were trained in a purely data-driven manner based on the scans and diagnosis labels. The high hippocampus relevance scores as well as the high performance achieved in independent samples support the validity of the CNN models in the detection of AD-related MRI abnormalities. The presented data-driven and hypothesis-free CNN modeling approach might provide a useful tool to automatically derive discriminative features for complex diagnostic tasks where clear clinical criteria are still missing, for instance for the differential diagnosis between various types of dementia.

Regular musical activity as a complex multimodal lifestyle activity is proposed to be protective against age-related cognitive decline and Alzheimer’s disease. This cross-sectional study investigated the association and interplay between musical instrument playing during life, multi-domain cognitive abilities and brain morphology in older adults from the DZNE-Longitudinal Cognitive Impairment and Dementia Study study. Participants reporting having played a musical instrument across three life periods were compared to controls without a history of musical instrument playing, well-matched for reserve proxies of education, (...) intelligence, socioeconomic status and physical activity. Participants with musical activity outperformed controls in global cognition, working memory, executive functions, language, and visuospatial abilities, with no effects seen for learning and memory. The musically active group had greater gray matter volume in the somatosensory area, but did not differ from controls in higher-order frontal, temporal, or hippocampal volumes. However, the association between gray matter volume in distributed frontal-to-temporal regions and cognitive abilities was enhanced in participants with musical activity compared to controls. We show that playing a musical instrument during life relates to better late-life cognitive abilities and greater brain capacities in OA. Musical activity may serve as a multimodal enrichment strategy that could help preserve cognitive and brain health in late life. Longitudinal and interventional studies are needed to support this notion. (shrink)

Worldwide implementation of the centrat concept sustainable development has given rise to very different interpretations, some extending to central issues within the field of ecological ethics. This is especially true of the two economic approaches termed >Strong weak weak strong< sustainability theory merits interdisciplinary consideration through a theologically oriented ethics of sustainable development.

The present article offers a discussion of the question 'Why study Cohen?′. The author′s first and preliminary answer to the question is that the study of Hermann Cohen′s thought is relevant for contemporary philosophy for at least five reasons. They include Cohen′s improvement of critical idealism of the subject which he substitutes with his idealism of the idea; the exposition of thought as an ethics of law; the articulation of the notion of anticipation as the principle of time, history, and (...) interpretation; the exposition of critical idealism as a form of idealism that is not violent, totalitarian or reductive, but idealism in terms of alterity and the other, instead; the role of history and especially the history of the religion of Judaism in the construction of the religion of reason and the conception of Judaism.

In this paper it is demonstrated how the understanding of resilience is enhanced and shaped when using the concepts of oikos and life-modes. Instead of applying a rather problematic welfare capitalism model, which partially provides a negative social reproduction and production, it is suggested to apply a household/family model. The household/family model outlines that positive social reproduction and production, including real and productive values, potentially creates an essential bond between viable household, family, work, socialisation, and network based communities, resulting in (...) socially, economically, mentally, and ecologically sustainable survival of families and livelihoods over generations. Furthermore, it is stressed that serious fallacies will occur if resilience is solely understood and explained in terms of individual resources and characteristics. Nonetheless, it is recognised that non-cognitive traits such as persistence are important. Offspring is more strongly socialised and positioned in intact and viable families by transmitting and practicing a set of long-term reproduction and production strategies, which compared to upper strata are less common in the lower and middle strata. Thus, resilience is unequal. (shrink)

This book is an analysis of the thought of Joseph B. Soloveitchik (1903-1993). The analysis focuses on Soloveitchik's notion of transcendence as articulated in his doctoral thesis on Hermann Cohen and in three of his essays on halakhic thought, viz., 'The Halakhic Mind', and the Hebrew essays 'Ish ha-halakha' and 'U-viqqashtem mi-sham'.

Hermann Lotze has truly said that “among all the errors of the human mind” the “strangest” is doubting its “own existence,” or regarding it “at second hand as the product of an external Nature” which can be known only “indirectly” while the mind knows itself directly. Yet this denial is found both in the Occident and in the Orient. Moreover, while in the latter it stems largely from an extreme form of idealism in terms of a reductionistic pantheism, in the (...) former it is almost altogether the result of an analytical, reductive naturalism. More specifically, in the West this impersonalistic tendency has really been the result of two movements which have merged in certain contemporary schools. (shrink)
