Learning Stochastic Majority Votes by Minimizing a PAC-Bayes Generalization Bound

We investigate a stochastic counterpart of majority votes over finite ensembles of classifiers, and study its generalization properties. While our approach holds for arbitrary distributions, we instantiate it with Dirichlet distributions: this allows for a closed-form and differentiable expression for the expected risk, which then turns the generalization bound into a tractable training objective.The resulting stochastic majority vote learning algorithm achieves state-of-the-art accuracy and benefits from (non-vacuous) tight generalization bounds, in a series of numerical experiments when compared to competing algorithms which also minimize PAC-Bayes objectives -- both with uninformed (data-independent) and informed (data-dependent) priors

Incidência de ferrugem em genótipos de amoreira-preta sob cobertura plástica.

Resumo: A cultura da amoreira-preta tem se tornado ao longo dos últimos anos importante para aumentar a renda de famílias de pequenas propriedades rurais. Porém, para atender a demanda de mercados consumidores, novas cultivares adaptadas devem ser introduzidas para produzir com qualidade. Entretanto, algumas novas variedades/seleções, apesar de produzirem frutos de elevada qualidade e de serem altamente produtivas, são suscetíveis à ferrugem, com tendência acentuada pelas características edafoclimáticas típicas da região de cultivo, como a Região dos Campos de Cima da Serra. O uso de coberturas plásticas pode ser um atenuante da incidência de doenças. O experimento foi conduzido a campo, sendo que as seleções de amoreira-preta Black 112, Black 178, Black 198 e as cultivares Cherokee e Brazos foram conduzidas com e sem cobertura plástica, buscando avaliar a incidência de ferrugem sobre as folhas. Para as condições nas quais foi desenvolvido o experimento pode-se concluir que as seleções Black 178, Black 198 e a cultivar Brazos apresentaram grau de resistência à ferrugem, mesmo em área sem cobertura plástica. A seleção Black 112 e a cultivar Cherokee mostraram-se suscetíveis à ferrugem. O uso de cobertura plástica foi eficiente em reduzir a incidência de ferrugem nas folhas de amoreira-preta.

Time for a paradigm shift in shared decision-making in trauma and emergency surgery? Results from an international survey

Background: Shared decision-making (SDM) between clinicians and patients is one of the pillars of the modern patient-centric philosophy of care. This study aims to explore SDM in the discipline of trauma and emergency surgery, investigating its interpretation as well as the barriers and facilitators for its implementation among surgeons. Methods: Grounding on the literature on the topics of the understanding, barriers, and facilitators of SDM in trauma and emergency surgery, a survey was created by a multidisciplinary committee and endorsed by the World Society of Emergency Surgery (WSES). The survey was sent to all 917 WSES members, advertised through the society’s website, and shared on the society’s Twitter profile. Results: A total of 650 trauma and emergency surgeons from 71 countries in five continents participated in the initiative. Less than half of the surgeons understood SDM, and 30% still saw the value in exclusively engaging multidisciplinary provider teams without involving the patient. Several barriers to effectively partnering with the patient in the decision-making process were identified, such as the lack of time and the need to concentrate on making medical teams work smoothly. Discussion: Our investigation underlines how only a minority of trauma and emergency surgeons understand SDM, and perhaps, the value of SDM is not fully accepted in trauma and emergency situations. The inclusion of SDM practices in clinical guidelines may represent the most feasible and advocated solutions

Neuroanatomy-based matrix-guided trimming protocol for the rat brain

Brain trimming through defined neuroanatomical landmarks is recommended to obtain consistent sections in rat toxicity studies. In this article, we describe a matrix-guided trimming protocol that uses channels to reproduce coronal levels of anatomical landmarks. Both setup phase and validation study were performed on Han Wistar male rats (Crl:WI(Han)), 10-week-old, with bodyweight of 298 \ub1 29 (SD) g, using a matrix (ASI-Instruments(\uae), Houston, TX) fitted for brains of rats with 200 to 400 g bodyweight. In the setup phase, we identified eight channels, that is, 6, 8, 10, 12, 14, 16, 19, and 21, matching the recommended landmarks midway to the optic chiasm, frontal pole, optic chiasm, infundibulum, mamillary bodies, midbrain, middle cerebellum, and posterior cerebellum, respectively. In the validation study, we trimmed the immersion-fixed brains of 60 rats using the selected channels to determine how consistently the channels reproduced anatomical landmarks. Percentage of success (i.e., presence of expected targets for each level) ranged from 89 to 100%. Where 100% success was not achieved, it was noted that the shift in brain trimming was toward the caudal pole. In conclusion, we developed and validated a trimming protocol for the rat brain that allow comparable extensiveness, homology, and relevance of coronal sections as the landmark-guided trimming with the advantage of being quickly learned by technicians
