Consistency Graph Modeling for Semantic Correspondence.

IEEE Trans Image Process 2021 13;30:4932-4946. Epub 2021 May 13.

To establish robust semantic correspondence between images covering different objects belonging to the same category, there are three important types of information including inter-image relationship, intra-image relationship and cycle consistency. Most existing methods only exploit one or two types of the above information and cannot make them enhance and complement each other. Different from existing methods, we propose a novel end-to-end Consistency Graph Modeling Network (CGMNet) for semantic correspondence by modeling inter-image relationship, intra-image relationship and cycle consistency jointly in a unified deep model.

Composition and origins of decorated glass from Umayyad Cordoba (Spain).

Herit Sci 2021 12;9(1):31. Epub 2021 Mar 12.

IRAMAT-CEB, UMR5060, CNRS/Université d'Orléans, 3D, Rue de la Férollerie, 45071 Orléans, France.

Recent archaeological excavations carried out in the western suburbs of Cordoba (Spain) brought to light numerous fragments of archaeological glass from the caliphal period (929-1031 CE). The typological and compositional analysis by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) of 66 fragments enabled the identification of different types of base glass and glass working techniques, identifying local productions, imports and decorative imitations of eastern models. The studied fragments include Mesopotamian, Levantine, Egyptian and possibly Sicilian soda-rich plant ash glass categories, and various glass-decorating techniques such as mould-blowing, pressing, cutting, staining or gilding.

Ka mura ka muri: understandings of organ donation and transplantation in Aotearoa New Zealand.

Med Humanit 2021 Mar 22. Epub 2021 Mar 22.

Criminology, Social Sciences, The University of Auckland, Auckland, New Zealand.

In this article, we refer to the separation of solid organs from the body as bio-objects. We suggest that the transfer of these bio-objects is connected to emotions and affects that carry a range of different social and cultural meanings specific to the context of Aotearoa New Zealand. The discussion draws on research findings from a series of qualitative indepth interview studies conducted from 2008 to 2013 with Māori (the Indigenous people of Aotearoa New Zealand) and Pākehā (European settler New Zealanders) concerning their views on organ donation and transplantation.

The hippocampal-entorhinal system represents nested hierarchical relations between words during concept learning.

Hippocampus 2021 Mar 6. Epub 2021 Mar 6.

CIMeC - Center for Mind/Brain Sciences, University of Trento, Rovereto, Italy.

A fundamental skill of an intelligent mind is that of being able to rapidly discover the structural organization underlying the relations across the objects or the events in the world. Humans, thanks to language, master this skill. For example, a child learning that dolphins and cats can also be referred to as mammals, not only will infer the presence of a hierarchical organization for which dolphins and cats are subordinate exemplars of the category mammals, but will also derive that dolphins are, at least at one conceptual level, more similar to cats than to sharks, despite their indisputable higher perceptual similarity to the latter.

Contrastive Similarity Matching for Supervised Learning.

Neural Comput 2021 Feb 22:1-29. Epub 2021 Feb 22.

John A. Paulson School of Engineering and Applied Sciences, Harvard University, Cambridge, MA 02138, U.S.A.

We propose a novel biologically plausible solution to the credit assignment problem motivated by observations in the ventral visual pathway and trained deep neural networks. In both, representations of objects in the same category become progressively more similar, while objects belonging to different categories become less similar. We use this observation to motivate a layer-specific learning goal in a deep network: each layer aims to learn a representational similarity matrix that interpolates between previous and later layers.

The differential power of extraneous influences to modify aesthetic judgments of biological and artifactual stimuli.

Psych J 2021 Apr 8;10(2):190-199. Epub 2020 Dec 8.

Laboratory of Neurobiology, Division of Cell and Developmental Biology, University College London, London, UK.

We addressed the question of the extent to which external information is capable of modifying aesthetic ratings given to two different categories of stimuli-images of faces (which belong to the biological category) and those of abstract paintings with no recognizable objects (which sit in the artifactual category). A total of 51 participants of different national origins rated the beauty of both sets of stimuli, indicating the certainty of their rating; they then re-rated them after being exposed to the opinions of others on their aesthetic status. Of these 51 participants, 42 who met our criteria were selected to complete the experiment. Read More

Social hierarchy and the choice of metal recycling at Anyang, the last capital of Bronze Age Shang China.

Sci Rep 2020 11 2;10(1):18794. Epub 2020 Nov 2.

Center for Social Sciences, Southern University of Science and Technology, Shenzhen, 518055, China.

Anyang, the last capital of the Chinese Shang dynasty, became one of the largest metal consumers in Eurasia during the second millennium BCE. However, it remains unclear how Anyang people managed to sustain such a large supply of metal. By considering the chemical analysis of bronze objects within archaeological contexts, this paper shows that the casting and circulation of metal at Anyang was effectively governed by social hierarchy.

FAME: 3D Shape Generation via Functionality-Aware Model Evolution.

IEEE Trans Vis Comput Graph 2020 Oct 12;PP. Epub 2020 Oct 12.

We introduce a modeling tool which can evolve a set of 3D objects in a functionality-aware manner. Our goal is for the evolution to generate large and diverse sets of plausible 3D objects for data augmentation, constrained modeling, as well as open-ended exploration to possibly inspire new designs. Starting with an initial population of 3D objects belonging to one or more functional categories, we evolve the shapes through part re-combination to produce generations of hybrids or crossbreeds between parents from the heterogeneous shape collection.

Is the Self other to the self? Why does the numinosum feel like another? The relevance of Matte Blanco to our understanding of the unconscious.

Authors:
Lionel Corbett

J Anal Psychol 2020 Sep;65(4):672-684

California, Santa Barbara.

Using Ignacio Matte Blanco's approach to the unconscious, this paper attempts to explain why the experience of the Self or the unconscious, for example in dreams, is difficult for the ego to understand. Matte Blanco believes that the logic of the unconscious is radically different from the logic of consciousness. The unconscious uses processes that Matte Blanco refers to as symmetry and generalization. Read More

Neurally plausible mechanisms for learning selective and invariant representations.

J Math Neurosci 2020 Aug 18;10(1):12. Epub 2020 Aug 18.

Laboratory for Computational and Statistical Learning (LCSL), Istituto Italiano di Tecnologia, Genova, Via Dodecaneso, Genova, Italy.

Coding for visual stimuli in the ventral stream is known to be invariant to object identity preserving nuisance transformations. Indeed, much recent theoretical and experimental work suggests that the main challenge for the visual cortex is to build up such nuisance invariant representations. Recently, artificial convolutional networks have succeeded in both learning such invariant properties and, surprisingly, predicting cortical responses in macaque and mouse visual cortex with unprecedented accuracy.

Human "resources"? Objectification at work.

J Pers Soc Psychol 2021 Feb 13;120(2):384-417. Epub 2020 Jul 13.

Haas School of Business, University of California, Berkeley.

People behave differently when at work than not at work; for example, they are less interested in making close friends and use more transactional language (networking vs. socializing). These examples hint at a broader phenomenon: that people engage in more objectification-treating people akin to objects-in work contexts than non work contexts. Read More
