TL;DR: ZeroEGGS, a neural network framework for speech-driven gesture generation with zero-shot style control by example is presented, which means style can be controlled via only a short example motion clip, even for motion styles unseen during training.
Abstract: We present ZeroEGGS, a neural network framework for speech‐driven gesture generation with zero‐shot style control by example. This means style can be controlled via only a short example motion clip, even for motion styles unseen during training. Our model uses a Variational framework to learn a style embedding, making it easy to modify style through latent space manipulation or blending and scaling of style embeddings. The probabilistic nature of our framework further enables the generation of a variety of outputs given the input, addressing the stochastic nature of gesture motion. In a series of experiments, we first demonstrate the flexibility and generalizability of our model to new speakers and styles. In a user study, we then show that our model outperforms previous state‐of‐the‐art techniques in naturalness of motion, appropriateness for speech, and style portrayal. Finally, we release a high‐quality dataset of full‐body gesture motion including fingers, with speech, spanning across 19 different styles. Our code and data are publicly available at https://github.com/ubisoft/ubisoft‐laforge‐ZeroEGGS.

TL;DR: In this paper, the authors compare popular fine-tuning measures with naturalness priors, which automatically appear in statistical measures of the plausibility that a given model reproduces the weak scale.
Abstract: The Higgs boson discovery stirred interest in next-to-minimal supersymmetric models, due to the apparent fine-tuning required to accommodate it in minimal theories. To assess their naturalness, we compare fine-tuning in a $\mathbb{Z}_3$ conserving semi-constrained Next-to-Minimal Supersymmetric Standard Model (NMSSM) to the constrained MSSM (CMSSM). We contrast popular fine-tuning measures with naturalness priors, which automatically appear in statistical measures of the plausibility that a given model reproduces the weak scale. Our comparison shows that naturalness priors provide valuable insight into the hierarchy problem and rigorously ground naturalness in Bayesian statistics. For the CMSSM and semi-constrained NMSSM we demonstrate qualitative agreement between naturalness priors and popular fine tuning measures. Thus, we give a clear plausibility argument that favours relatively light superpartners.

TL;DR: In this article, the interplay of linguistics, social situations, and mathematical formalisms as they affect certain speaker-addressee relationships involving three people is studied. But the choice of best representation has been made on sociolinguistic grounds, and it turns out-to our delight-to combine, as mathematical characteristics, those of the minimum non-commutative group with those of a minimum (non-trivial) commutative groups.
Abstract: Some characteristics of pronoun sequences are structured so as to necessitate the postulation of components of discourse structures-larger than the sentencewhich can now be treated by the mathematical theory of groups (and in a manner accessible to the non-mathematician). Since dozens of variant formalisms can represent the six pronominal axes studied, criteria outside formalism are needed to evaluate them. In seeking for naturalness, sociolinguistic criteria (beyond grammar or lexicon as such) must be used. Once the choice of best representation has been made on sociolinguistic grounds, it turns out-to our delight-to combine, as mathematical characteristics, those of the minimum non-commutative group with those of the minimum (non-trivial) commutative group. This article studies the interplay of linguistics, social situations, and mathematical formalisms as they affect certain speaker-addressee relationships involving three people. In ?1 a few questions are raised about linguistic use of such relations, to suggest to the reader the general area of interest. ?2 develops, through the use of graphs, the small amount of mathematics needed by the mathematical layman in order to follow our argument. ??3-9 discuss and evaluate the many alternatives, partially ranking them in order of naturalness. ??10-13 return to more general considerations, and end with the conclusion that the choice arrived at empirically, for greatest naturalness, has interesting mathematical properties as well.*

TL;DR: The development of a mathematical model to predict the perception of naturalness for a range of materials, based on an understanding of the relationship between the physical attributes of the material and the human sensory inputs is presented.
Abstract: This paper presents the development of a mathematical model to predict the perception of naturalness for a range of materials, based on an understanding of the relationship between the physical attributes of the material and the human sensory inputs. The work is being carried out under an European Union project called 'Measurement of Naturalness' (MONAT), which focuses on understanding the relationships between the physical properties of natural and synthetic materials and the visual and tactile sensory processes that lead to perceptual judgments of naturalness. Integral to the project is the development of novel measurement facilities with dynamic ranges and sensitivities that are relevant for the human sensory systems. The input data to the model are derived from psychophysical and physical studies on pre-selected wood, textile and stone samples. Keyword s: regression, sensory metrology, perception

01 Apr 2022TL;DR: In this paper , it was shown that such systems have relevant deformations with exactly-calculable effects, which allow one to dial the vacuum energy densities of the universes.
Abstract: QFTs with local topological operators feature unusual sectors called ``universes,'' which are separated by infinite-tension domain walls. We show that such systems have relevant deformations with exactly-calculable effects. These deformations allow one to dial the vacuum energy densities of the universes. We describe applications of these deformations to confinement in 2d gauge theories, as well as a curious violation of the effective field theory naturalness principle.
