Investigation and analysis of patient outcomes, including in-hospital mortality and length of stay, are crucial for assisting clinicians in determining a patient's result at the outset of their hospitalization and for assisting hospitals in allocating their resources. This paper proposes an approach based on combining the well-known gray wolf algorithm with frequent items extracted by association rule mining algorithms. First, original features are combined with the discriminative extracted frequent items. The best subset of these features is then chosen, and the parameters of the used classification algorithms are also adjusted, using the gray wolf algorithm. This framework was evaluated using a real dataset made up of 2816 patients from the Imam Ali Kermanshah Hospital in Iran. The study's findings indicate that low Ejection Fraction, old age, high CPK values, and high Creatinine levels are the main contributors to patients' mortality. Several significant and interesting rules related to mortality in hospitals and length of stay have also been extracted and presented. Additionally, the accuracy, sensitivity, specificity, and auroc of the proposed framework for the diagnosis of mortality in the hospital using the SVM classifier were 0.9961, 0.9477, 0.9992, and 0.9734, respectively. According to the framework's findings, adding frequent items as features considerably improves classification accuracy.

Computing systems are tightly integrated today into our professional, social, and private lives. An important consequence of this growing ubiquity of computing is that it can have significant ethical implications of which computing professionals should take account. In most real-world scenarios, it is not immediately obvious how particular technical choices during the design and use of computing systems could be viewed from an ethical perspective. This article provides a perspective on the ethical challenges within semiconductor chip design, IoT applications, and the increasing use of artificial intelligence in the design processes, tools, and hardware-software stacks of these systems.

A master face is a face image that passes face-based identity authentication for a high percentage of the population. These faces can be used to impersonate, with a high probability of success, any user, without having access to any user information. We optimize these faces for 2D and 3D face verification models, by using an evolutionary algorithm in the latent embedding space of the StyleGAN face generator. For 2D face verification, multiple evolutionary strategies are compared, and we propose a novel approach that employs a neural network to direct the search toward promising samples, without adding fitness evaluations. The results we present demonstrate that it is possible to obtain a considerable coverage of the identities in the LFW or RFW datasets with less than 10 master faces, for six leading deep face recognition systems. In 3D, we generate faces using the 2D StyleGAN2 generator and predict a 3D structure using a deep 3D face reconstruction network. When employing two different 3D face recognition systems, we are able to obtain a coverage of 40%-50%. Additionally, we present the generation of paired 2D RGB and 3D master faces, which simultaneously match 2D and 3D models with high impersonation rates.

Large language models (LLMs) have been shown to be able to perform new tasks based on a few demonstrations or natural language instructions. While these capabilities have led to widespread adoption, most LLMs are developed by resource-rich organizations and are frequently kept from the public. As a step towards democratizing this powerful technology, we present BLOOM, a 176B-parameter open-access language model designed and built thanks to a collaboration of hundreds of researchers. BLOOM is a decoder-only Transformer language model that was trained on the ROOTS corpus, a dataset comprising hundreds of sources in 46 natural and 13 programming languages (59 in total). We find that BLOOM achieves competitive performance on a wide variety of benchmarks, with stronger results after undergoing multitask prompted finetuning. To facilitate future research and applications using LLMs, we publicly release our models and code under the Responsible AI License.

ICECUBE是一种用于检测1 GEV和1 PEV之间大气和天体中微子的光学传感器的立方公斤阵列,该阵列已部署1.45 km至2.45 km的南极的冰盖表面以下1.45 km至2.45 km。来自ICE探测器的事件的分类和重建在ICeCube数据分析中起着核心作用。重建和分类事件是一个挑战,这是由于探测器的几何形状,不均匀的散射和冰中光的吸收,并且低于100 GEV的光,每个事件产生的信号光子数量相对较少。为了应对这一挑战,可以将ICECUBE事件表示为点云图形,并将图形神经网络(GNN)作为分类和重建方法。 GNN能够将中微子事件与宇宙射线背景区分开,对不同的中微子事件类型进行分类,并重建沉积的能量,方向和相互作用顶点。基于仿真,我们提供了1-100 GEV能量范围的比较与当前ICECUBE分析中使用的当前最新最大似然技术,包括已知系统不确定性的影响。对于中微子事件分类,与当前的IceCube方法相比,GNN以固定的假阳性速率(FPR)提高了信号效率的18%。另外,GNN在固定信号效率下将FPR的降低超过8(低于半百分比)。对于能源,方向和相互作用顶点的重建,与当前最大似然技术相比,分辨率平均提高了13%-20%。当在GPU上运行时,GNN能够以几乎是2.7 kHz的中位数ICECUBE触发速率的速率处理ICECUBE事件,这打开了在在线搜索瞬态事件中使用低能量中微子的可能性。

在恶性原发性脑肿瘤中,癌细胞浸润到周围的脑结构中,导致不可避免的复发。对周围区域的浸润性异质性(活检或切除可能是危险的区域)的定量评估对于临床决策很重要。以前关于表征周围区域浸润性异质性的工作使用了各种成像方式,但是已经探索了细胞外无水运动限制的信息。在这里,我们通过使用基于扩散的张量成像(DTI)的自由水量分数图来表征一组独特的人工智能(AI)标记,从而捕获肿瘤浸润的异质性,从而捕获肿瘤的异质性。首先通过利用胶质母细胞瘤和脑转移的广泛不同的水扩散性能作为在周围肿瘤组织中有和没有浸润的区域的区域,首先提取了一种新型的基于体素的深度学习周围微环境指数(PMI)。均匀高PMI值的局部枢纽的描述性特征被提取为基于AI的标记,以捕获渗透性异质性的不同方面。提出的标记物应用于两个临床用例,对275个成人型弥漫性神经胶质瘤的独立人群(4级)分析,分析异氯酸盐 - 脱水酶1(IDH1) - wildtypes之间的生存持续时间以及带有IDH1-杀剂的差异。我们的发现提供了一系列标记物作为浸润的替代物,可捕获有关周围微观结构异质性生物学潜在生物学的独特见解,使其成为与生存和分子分层有关的预后生物标志物,并具有潜在的适用性在临床决策中。

我们提出了一个新的图神经网络(GNN)模块,该模块基于最近提出的几何散射变换的松弛,该变换由图形小波滤波器组成。我们可学习的几何散射(腿)模块可以使小波的自适应调整能够鼓励乐队通道特征在学习的表示中出现。与许多流行的GNN相比,我们的腿部模块在GNN中的结合能够学习长期图形关系,这些GNN通常依赖于邻居之间的平滑度或相似性来编码图形结构。此外,与竞争性GNN相比,其小波先验会导致简化的架构,学到的参数明显少得多。我们证明了基于腿的网络在图形分类基准上的预测性能,以及在生化图数据探索任务中学到的功能的描述性质量。我们的结果表明,基于腿部的网络匹配或匹配流行的GNN,以及在许多数据集上,尤其是在生化域中的原始几何散射结构,同时保留了手工制作的(非学习)几何散射的某些数学特性。
