Diagnostic Cue

Could a simple rule of thumb help to find the truth? People struggle with integrating many putative cues to deception into an accurate veracity judgement. Heuristics simplify difficult decisions by ignoring most of the information and relying instead only on a few but highly diagnostic cues (’Use the best, ignore the rest’). We examined whether people would be able to tell lie from truth when instructed to make decisions based on a single, diagnostic cue (verifiability and richness in detail). We show that these simple judgements by lay people allowed to discriminate dishonest from honest statements. These judgements performed at or above state-of-the-art, resource-intensive content analysis by trained coders. For a tech- and training-free approach, heuristics were surprisingly accurate, and hold promise for practice.

With recent advances in technologies, deep learning is being applied more and more to different tasks. In particular, point cloud processing and classification have been studied for a while now, with various methods developed. Some of the available classification approaches are based on specific data source, like LiDAR, while others are focused on specific scenarios, like indoor. A general major issue is the computational efficiency (in terms of power consumption, memory requirement, and training/inference time). In this study, we propose an efficient framework (named TONIC) that can work with any kind of aerial data source (LiDAR or photogrammetry) and does not require high computational power while achieving accuracy on par with the current state of the art methods. We also test our framework for its generalization ability, showing capabilities to learn from one dataset and predict on unseen aerial scenarios.

This article builds a mapping in order to analyze the theses and dissertations about body, health, curriculum and training of health professionals. For this, theses and dissertations were mapped in the period from 2010 to 2020 through a state-of-the-art study. The composition of the data is given by the presentation and discussion of the listed texts. As for research, these concern the production of bodies based on biotechnological discourses; professional training in health; others point to the curricula of health courses after the National Curriculum Guidelines (DCN); the performance of health professionals in relation to the Unified Health System (SUS); teaching strategies for health training; corporeidity in the curricula, especially in the curricula of the Physical Education course; the anatomoclinical body and educational health practices. In this perspective, some contributions, limits and possibilities of this academic production were observed.

Abstract. The Met Office Unified Model (UM) is a state-of-the-art weather and climate model that is used operationally worldwide. UKCA is the chemistry and aerosol sub model of the UM that enables interactive composition and physical atmosphere interactions, but which adds an additional 120 000 lines of code to the model. Ensuring that the UM code and UM-UKCA (the UM running with interactive chemistry and aerosols) is well tested is thus essential. While a comprehensive test harness is in place at the Met Office and partner sites to aid in development, this is not available to many UM users. Recently, the Met Office have made available a virtual machine environment that can be used to run the UM on a desktop or laptop PC. Here we describe the development of a UM-UKCA configuration that is able to run within this virtual machine while only needing 6 GB of memory, before discussing the applications of this system for model development, testing, and training.

In the pursuit of identify ways for a better understanding the barriers of the dairy production system, we sought to diagnose them from the perspective of the business ecosystem concept, through a systematic literature review. Thus, we use content analysis to serve as the basis for analysis and discussion of the barriers of dairy production. Resulting a total of fifteen barriers, properly presented and discussed. In addition, we provide some insights to mitigate these barriers. The study presents contribution to the development of dairy production by providing assistance to develop strategies for producers’ cooperatives, government agencies, milk producers, hulling industries products from milk. Based on the perspective of the business ecosystem is possible to have a broader view of the scenario where dairy production occurs and recognize the barriers of dairy production system. And once identified these barriers, it is possible to devise strategies to eliminate or mitigate these barriers.

Machine Learning Models

Missing data is a problem often found in real-world datasets and it can degrade the performance of most machine learning models. Several deep learning techniques have been used to address this issue, and one of them is the Autoencoder and its Denoising and Variational variants. These models are able to learn a representation of the data with missing values and generate plausible new ones to replace them. This study surveys the use of Autoencoders for the imputation of tabular data and considers 26 works published between 2014 and 2020. The analysis is mainly focused on discussing patterns and recommendations for the architecture, hyperparameters and training settings of the network, while providing a detailed discussion of the results obtained by Autoencoders when compared to other state-of-the-art methods, and of the data contexts where they have been applied. The conclusions include a set of recommendations for the technical settings of the network, and show that Denoising Autoencoders outperform their competitors, particularly the often used statistical methods.

Construction chemistry is underdeveloped compared to other chemical branches. Innovation is realized by new products, improved pro¬cesses or / and more efficient organization. Innovation becomes evident when a noticeable progress is achieved by implementing changes. There are seven fundamental hindrances or flaws possible which are briefly considered. The state-of-the-art must be known. Innovation is measured in comparison to this state-of-the-art. If this level is not yet attained, progress is easily realized by introducing the actual knowledge. The realization is measured according to qualitative or preferably quantitative bench¬marks. Unfortunately, this is not currently done in the field of construction chemistry. Before benchmarking starts, communication based on truth and trust must be effective. The available scientific me¬tho¬dology must be known. Benchmarking will possibly show deficiencies in education and training. This will stress the need for adequate trans¬parency to improve efficiency. Hope¬ful¬ly, a self-regulating process improving pro-ducts and processes will be created in this way.

Emotion recognition in user-generated videos plays an important role in human-centered computing. Existing methods mainly employ traditional two-stage shallow pipeline, i.e. extracting visual and/or audio features and training classifiers. In this paper, we propose to recognize video emotions in an end-to-end manner based on convolutional neural networks (CNNs). Specifically, we develop a deep Visual-Audio Attention Network (VAANet), a novel architecture that integrates spatial, channel-wise, and temporal attentions into a visual 3D CNN and temporal attentions into an audio 2D CNN. Further, we design a special classification loss, i.e. polarity-consistent cross-entropy loss, based on the polarity-emotion hierarchy constraint to guide the attention generation. Extensive experiments conducted on the challenging VideoEmotion-8 and Ekman-6 datasets demonstrate that the proposed VAANet outperforms the state-of-the-art approaches for video emotion recognition. Our source code is released at: https://github.com/maysonma/VAANet.
