A total of 605 eligible respondents took part in this survey (population size 1630046161 and required sample size 591) with an age range of 18 to 100. A large proportion of the respondents are aged less than 50 (82%) and male (62.15%). The majority of the respondents live in urban areas (60.83%). A total of 61.16% (370/605) of the respondents were willing to accept/take the COVID-19 vaccine. Among the accepted group, only 35.14% showed the willingness to take the COVID-19 vaccine immediately, while 64.86% would delay the vaccination until they are confirmed about the vaccine s efficacy and safety or COVID-19 becomes deadlier in Bangladesh. The regression results showed age, gender, location (urban/rural), level of education, income, perceived risk of being infected with COVID-19 in the future, perceived severity of infection, having previous vaccination experience after age 18, having higher knowledge about COVID-19 and vaccination were significantly associated with the acceptance of COVID-19 vaccines. The research reported a high prevalence of COVID-19 vaccine refusal and hesitancy in Bangladesh.

To ensure proper knowledge representation of the kitchen environment, it is vital for kitchen robots to recognize the states of the food items that are being cooked. Although the domain of object detection and recognition has been extensively studied, the task of object state classification has remained relatively unexplored. The high intra-class similarity of ingredients during different states of cooking makes the task even more challenging. Researchers have proposed adopting Deep Learning based strategies in recent times, however, they are yet to achieve high performance. In this study, we utilized the self-attention mechanism of the Vision Transformer (ViT) architecture for the Cooking State Recognition task. The proposed approach encapsulates the globally salient features from images, while also exploiting the weights learned from a larger dataset. This global attention allows the model to withstand the similarities between samples of different cooking objects, while the employment of transfer learning helps to overcome the lack of inductive bias by utilizing pretrained weights. To improve recognition accuracy, several augmentation techniques have been employed as well. Evaluation of our proposed framework on the `Cooking State Recognition Challenge Dataset' has achieved an accuracy of 94.3%, which significantly outperforms the state-of-the-art.

Sparse matrix representations are ubiquitous in computational science and machine learning, leading to significant reductions in compute time, in comparison to dense representation, for problems that have local connectivity. The adoption of sparse representation in leading ML frameworks such as PyTorch is incomplete, however, with support for both automatic differentiation and GPU acceleration missing. In this work, we present an implementation of a CSR-based sparse matrix wrapper for PyTorch with CUDA acceleration for basic matrix operations, as well as automatic differentiability. We also present several applications of the resulting sparse kernels to optimization problems, demonstrating ease of implementation and performance measurements versus their dense counterparts.

我们研究了使用社交媒体数据预测加密货币未来表现的问题。我们提出了一个新模型，以根据与社交媒体帖子的互动来衡量用户与社交媒体讨论的主题的参与。该模型克服了以前的卷和基于情感的方法的局限性。我们使用此模型来估计2019年至2021年之间使用来自加密货币存在的第一个月的数据在2019年至2021年之间创建的48个加密货币的参与系数。我们发现加密货币的未来回报取决于参与系数。参与系数太低或太高的加密货币的回报较低。低参与系数表明缺乏兴趣，而高参与系数信号是人工活动，这可能来自自动化的bot。我们测量了加密货币的机器人柱数量，并发现通常，具有更多机器人柱的加密货币的未来回报较低。尽管未来的回报取决于机器人活动和参与系数，但依赖性对于参与系数最强，尤其是对于短期收益。我们显示，以超过固定阈值的参与系数选择加密货币的简单投资策略在几个月的固定时间内表现良好。

我们考虑在平均场比赛中在线加强学习。与现有作品相反，我们通过开发一种使用通用代理的单个样本路径来估算均值场和最佳策略的算法来减轻对均值甲骨文的需求。我们称此沙盒学习为其，因为它可以用作在多代理非合作环境中运行的任何代理商的温暖启动。我们采用了两种时间尺度的方法，在该方法中，平均场的在线固定点递归在较慢的时间表上运行，并与通用代理更快的时间范围内的控制策略更新同时进行。在足够的勘探条件下，我们提供有限的样本收敛保证，从平均场和控制策略融合到平均场平衡方面。沙盒学习算法的样本复杂性为$ \ Mathcal {o}（\ epsilon^{ - 4}）$。最后，我们从经验上证明了沙盒学习算法在交通拥堵游戏中的有效性。

最近显示外部眼睛照片显示出糖尿病性视网膜疾病和HBA1C升高的迹象。在本文中，我们评估外部眼睛照片是否包含有关其他系统性医疗状况的信息。我们开发了一个深度学习系统（DLS），该系统将外部眼睛的照片作为输入，并预测多个全身参数，例如与肝脏有关的参数（白蛋白，AST）；肾脏（EGFR使用无种族的2021 CKD-EPI肌酐方程，尿液ACR）；骨与矿物质（钙）;甲状腺（TSH）;和血数（HGB，WBC，血小板）。开发利用了49,015例糖尿病患者的151,237张图像，在加利福尼亚州洛杉矶县的11个地点接受糖尿病眼镜筛查。评估重点是9个预先指定的全身参数，并利用了3个验证集（a，b，c），涵盖了28,869名患有和没有糖尿病的患者，在加利福尼亚州洛杉矶县和大亚特兰大地区的3个独立地点进行了眼睛筛查。我们将结合了可用临床人口统计学变量的基线模型（例如年龄，性别，种族/种族，糖尿病年）进行了比较。相对于基线，DLS在检测AST> 36，钙<8.6，egfr <60，HGB <11，血小板<150，ACR> = 300和WBC <4时，在检测AST> 36，钙<8.6，Egfr <60，HGB <60，HGB <60，calcium <8.6，Egfr <60，calcium <8.6和wbc <4时，达到了统计学上的显着性能，并且类似于开发集的人口），其中DLS的AUC超过基线的AUC，增长了5.2-19.4％。在验证集B和C方面，与开发集相比，患者人群的差异很大，DLS的表现优于ACR> = 300的基线，而HGB <11升至7.3-13.2％。我们的发现提供了进一步的证据，表明外部眼睛照片包含跨越多器官系统的全身健康生物标志物。需要进一步的工作来研究这些生物标志物是否以及如何转化为临床影响。

使用摄像机和计算算法的生理学（例如心脏和肺）生理学的非侵入性，低成本和可扩展性测量的生命体征非常有吸引力。但是，代表各种环境，身体运动，照明条件和生理状态的各种数据是费力的，耗时且昂贵的。合成数据已被证明是机器学习的几个领域的有价值工具，但并未广泛用于摄像机测量生理状态。合成数据提供“完美”标签（例如，没有噪声且具有精确的同步），可能无法获得其他标签（例如，精确的像素级分段图），并提供了对数据集中变化和多样性的高度控制。我们提供Scamps，这是一个合成学数据集，其中包含2,800个视频（168万帧），并带有对齐的心脏和呼吸信号以及面部动作强度。 RGB框架与分割图一起提供。我们提供有关潜在波形的精确描述性统计数据，包括beat间间隔，心率变异性和脉搏到达时间。最后，我们介绍了这些合成数据和对现实世界数据集测试的基线结果培训，以说明可推广性。

Insects are the most important global pollinator of crops and play a key role in maintaining the sustainability of natural ecosystems. Insect pollination monitoring and management are therefore essential for improving crop production and food security. Computer vision facilitated pollinator monitoring can intensify data collection over what is feasible using manual approaches. The new data it generates may provide a detailed understanding of insect distributions and facilitate fine-grained analysis sufficient to predict their pollination efficacy and underpin precision pollination. Current computer vision facilitated insect tracking in complex outdoor environments is restricted in spatial coverage and often constrained to a single insect species. This limits its relevance to agriculture. Therefore, in this article we introduce a novel system to facilitate markerless data capture for insect counting, insect motion tracking, behaviour analysis and pollination prediction across large agricultural areas. Our system is comprised of edge computing multi-point video recording, offline automated multispecies insect counting, tracking and behavioural analysis. We implement and test our system on a commercial berry farm to demonstrate its capabilities. Our system successfully tracked four insect varieties, at nine monitoring stations within polytunnels, obtaining an F-score above 0.8 for each variety. The system enabled calculation of key metrics to assess the relative pollination impact of each insect variety. With this technological advancement, detailed, ongoing data collection for precision pollination becomes achievable. This is important to inform growers and apiarists managing crop pollination, as it allows data-driven decisions to be made to improve food production and food security.
