TL;DR: This work proposes to use Multi-Task Learning (MTL) and use gender and naturalness as auxiliary tasks in deep neural networks and found that the MTL method proposed improved performance significantly.
Abstract: One of the challenges in Speech Emotion Recognition (SER) "in the wild" is the large mismatch between training and test data (e.g. speakers and tasks). In order to improve the generalisation capabilities of the emotion models, we propose to use Multi-Task Learning (MTL) and use gender and naturalness as auxiliary tasks in deep neural networks. This method was evaluated in within-corpus and various cross-corpus classification experiments that simulate conditions "in the wild". In comparison to Single-Task Learning (STL) based state of the art methods, we found that our MTL method proposed improved performance significantly. Particularly, models using both gender and naturalness achieved more gains than those using either gender or naturalness separately. This benefit was also found in the high-level representations of the feature space, obtained from our method proposed, where discriminative emotional clusters could be observed.

TL;DR: In this paper, a calculation scheme of radiative corrections utilizing a hidden duality was proposed, in the expectation that the unnaturalness for scalar masses might be an artifact in the effective theory and it could be improved if features of an ultimate theory are taken in.
Abstract: We reconsider the naturalnessfrom the viewpoint of effective field theories, motivatedbythealternativescenariothatthestandardmodelholdsuntila high-energy scale such as the Planck scale. We propose a calculation scheme of radiative corrections utilizing a hidden duality, in the expectation that the unnaturalness for scalar masses might be an artifact in the effective theory and it could be improved if features of an ultimate theory are taken in.

TL;DR: In this article, a model is introduced to account for the results of a previous study that explored how the perceived naturalness of music and speech signals was affected by various forms of linear filtering.
Abstract: In a previous study it was explored how the perceived naturalness of music and speech signals was affected by various forms of linear filtering. In the present paper a model is introduced to account for the results. The model is based on the assumption that changes in perceived naturalness produced by linear filtering can be characterized in terms of the changes in the excitation pattern produced by the filtering. The model takes into account both the magnitude of the changes in the excitation pattern and the rapidity with which the excitation pattern changes as a function of frequency. It also includes frequency-weighting functions to take into account the fact that naturalness is affected little by changes in amplitude response at very low and very high frequencies. The model accounts very well for the data presented in the earlier study. Two validation experiments were conducted in which naturalness ratings were obtained for speech and music stimuli passed through new sets of linear filters, including filters based on the measured frequency responses of real transducers. The model predicted the results of these experiments well.

TL;DR: The focus point supersymmetry and inverted hierarchy supersymmetric models as mentioned in this paper relax the naturalness constraint of split supersymmetrization, which relaxes the superpartners' masses well above weak scale.

TL;DR: For decades, the unnaturalness of the weak scale has been the dominant problem motivating new particle physics, and weak-scale supersymmetry has become the dominant solution as discussed by the authors. But this paradigm is now being challenged by a wealth of experimental data.
Abstract: For decades, the unnaturalness of the weak scale has been the dominant problem motivating new particle physics, and weak-scale supersymmetry has been the dominant proposed solution. This paradigm is now being challenged by a wealth of experimental data. In this review, we begin by recalling the theoretical motivations for weak-scale supersymmetry, including the gauge hierarchy problem, grand unification, and WIMP dark matter, and their implications for superpartner masses. These are set against the leading constraints on supersymmetry from collider searches, the Higgs boson mass, and low-energy constraints on flavor and CP violation. We then critically examine attempts to quantify naturalness in supersymmetry, stressing the many subjective choices that impact the results both quantitatively and qualitatively. Finally, we survey various proposals for natural supersymmetric models, including effective supersymmetry, focus point supersymmetry, compressed supersymmetry, and R-parity-violating supersymmetry, and summarize their key features, current status, and implications for future experiments.
