Disentangled Representation Learning GAN for Pose-Invariant Face Recognition

Abstract: The large pose discrepancy between two face images is one of the key challenges in face recognition. Conventional approaches for pose-invariant face recognition either perform face frontalization on, or learn a pose-invariant representation from, a non-frontal face image. We argue that it is more desirable to perform both tasks jointly to allow them to leverage each other. To this end, this paper proposes Disentangled Representation learning-Generative Adversarial Network (DR-GAN) with three distinct novelties. First, the encoder-decoder structure of the generator allows DR-GAN to learn a generative and discriminative representation, in addition to image synthesis. Second, this representation is explicitly disentangled from other face variations such as pose, through the pose code provided to the decoder and pose estimation in the discriminator. Third, DR-GAN can take one or multiple images as the input, and generate one unified representation along with an arbitrary number of synthetic images. Quantitative and qualitative evaluation on both controlled and in-the-wild databases demonstrate the superiority of DR-GAN over the state of the art.

The Performance of Incumbent firms in the Face of Radical Technological Innovation

Abstract: A persistent theme in the academic literature on technological innovation is that incumbent enterprises have great difficulty crossing the abyss created by a radical technological innovation and, thus, go into decline, while new entrants rise to market dominance by exploiting the new technology. However, this tendency is not universal. There are outliers in any population, and much can be learned from examining this group. Here we identify a number of factors that help to explain incumbent performance in markets shaken by a radical technological innovation.

Stereotypes as energy-saving devices: A peek inside the cognitive toolbox.

Abstract: By use of a dual-task paradigm, 3 studies investigated the contention that stereotypes function as resource-preserving devices in mental life. In Study 1, Ss formed impressions of targets while simultaneously monitoring a prose passage. The results demonstrated a significant enhancement in Ss' prose-monitoring performance when stereotype labels were present on the impression-formation task. To investigate the intentionality of this effect, in Study 2, the procedures used in Study 1 were repeated using a subliminal priming procedure to activate stereotypes. Subliminal activation of stereotypes produced the same resource-preserving effects as supraliminal activation did. This effect, moreover, was replicated in Study 3 when a probe reaction task was used to measure resource preservation. These findings, which generalized across a range of social stereotypes, are discussed in terms of their implications for contemporary models of stereotyping and social inference. Human adaptation to the challenging and complex environment has often taken the form of developing tools that facilitate the execution of mundane but necessary tasks, leaving more time and energy available for other, perhaps more interesting or rewarding activities. It is reasonable to suppose, as some contemporary psychologists have, that the development of physical tools, such as plows or printing presses, has been paralleled by the development of cognitive "tools," or routine strategies of inference and evaluation (cf. Tooby & Cosmides, 1990) that permit a sufficiently effective analysis of the social environment to be accomplished in an efficient fashion. The benefit of such mental tools presumably lies in the fact that they free up limited cognitive resources for the performance of other necessary or desirable mental activities. Social psychologists have frequently characterized stereotypes as energy-saving devices that serve the important cognitive function of simplifying information processing and response generation (e.g., Allport, 1954; Andersen, Klatzky, & Murray, 1990; Bodenhausen & Lichtenstein, 1987; Brewer, 1988; Fiske & Neuberg, 1990; Tajfel, 1969). Building on this tradition, Gilbert and Hixon (1991) aptly characterized stereotypes as "tools that jump out" of a metaphorical cognitive toolbox "when there is a job to be done" (p. 510). Anyone who has ever succumbed to the temptation to evaluate others in terms of their social group membership would doubtlessly recognize the power of this contention. Individuation, in its many guises, is a rather

A reference genome for common bean and genome-wide analysis of dual domestications

Abstract: Common bean (Phaseolus vulgaris L.) is the most important grain legume for human consumption and has a role in sustainable agriculture owing to its ability to fix atmospheric nitrogen. We assembled 473 Mb of the 587-Mb genome and genetically anchored 98% of this sequence in 11 chromosome-scale pseudomolecules. We compared the genome for the common bean against the soybean genome to find changes in soybean resulting from polyploidy. Using resequencing of 60 wild individuals and 100 landraces from the genetically differentiated Mesoamerican and Andean gene pools, we confirmed 2 independent domestications from genetic pools that diverged before human colonization. Less than 10% of the 74 Mb of sequence putatively involved in domestication was shared by the two domestication events. We identified a set of genes linked with increased leaf and seed size and combined these results with quantitative trait locus data from Mesoamerican cultivars. Genes affected by domestication may be useful for genomics-enabled crop improvement.
