Recently, psychologist has experienced drastic development using statistical methods to analyze the interactions of humans. The intention of past decades of psychological studies is to model how individuals learn elements and types. The scientific validation of such studies is often based on straightforward illustrations of artificial stimuli. Recently, in activities such as recognizing items in natural pictures, strong neural networks have reached or exceeded human precision. In this paper, we present Relevance Networks (RNs) as a basic plug-and-play application with Covolutionary Neural Network (CNN) to address issues that are essentially related to reasoning. Thus our proposed network performs visual answering the questions, superhuman performance and text based answering. All of these have been accomplished by complex reasoning on diverse physical systems. Thus, by simply increasing convolutions, (Long Short Term Memory) LSTMs, and (Multi-Layer Perceptron) MLPs with RNs, we can remove the computational burden from network components that are unsuitable for handling relational reasoning, reduce the overall complexity of the network, and gain a general ability to reason about the relationships between entities and their properties.
近年来,心理学家利用统计方法来分析人与人之间的相互作用有了很大的发展。过去几十年心理学研究的目的是建立个体如何学习元素和类型的模型。这类研究的科学验证往往基于人工刺激的直接例证。最近,在识别自然图片中的物品等活动中,强大的神经网络已经达到或超过了人类的精度。在本文中,我们将相关网络(RNs)作为一种基本的即插即用应用,与进化神经网络(CNN)一起解决本质上与推理相关的问题。因此,我们提出的网络可以实现视觉回答问题、超人的表现和基于文本的回答。所有这些都是通过在不同物理系统上的复杂推理完成的。因此,通过简单地增加卷积、(长短期记忆)lstm和(多层感知器)mlp与RNs,我们可以从不适合处理关系推理的网络组件中消除计算负担,降低网络的整体复杂性,并获得对实体及其属性之间关系进行推理的一般能力。

The energy consumption is becoming a constraint on all computer devices, from smartphones to supercomputers. Consequently, the focus has moved from performance to energy and power consumption. Design metrics are not only based solely on performance, as the energy performance of application executions is becoming the main aspect of architecture. Also, Design metrics depend on, the manufacturers of semiconductor chips which, have implemented multicore processors to boost the level of energy efficiency by using verified techniques for voltage and frequency scaling. To utilize the maximum potential of such architectures, we need to make the right decisions because parameters such as core type, frequency, and utilization typically affect power dissipation and performance. This paper proposes a new algorithm to achieve energy-efficient by monitoring core energy and level utilization control such as: Increasing the number of cores to execute the task, scaling voltage, and frequency. Based on the built model, we analyze the energy efficiency variations for different platform configurations providing the same level of performance. We show that trading the number and type of core with frequency and voltage level and core utilization rate can lead to substantial energy efficiency gains.
从智能手机到超级计算机,能源消耗正成为所有计算机设备的制约因素。因此,重点已经从性能转移到能源和功耗。设计度量不仅仅基于性能,因为应用程序执行的能源性能正在成为体系结构的主要方面。此外,设计指标取决于半导体芯片制造商,他们已经实施了多核处理器,通过使用经过验证的电压和频率缩放技术来提高能效水平。为了最大限度地利用这种架构的潜力,我们需要做出正确的决策,因为内核类型、频率和利用率等参数通常会影响功耗和性能。本文提出了一种新的算法,通过增加执行任务的核数、缩放电压和频率来监测核能量和电平利用控制,从而实现节能。基于构建的模型,我们分析了提供相同性能水平的不同平台配置的能效变化。我们表明,将核心的数量和类型与频率和电压水平以及核心利用率进行交易可以导致大量的能源效率收益。

Lossless Compression of Medical Images based on the Differential Probability of Images 基于图像差分概率的医学图像无损压缩
Pub Date : 2020-04-30 DOI: 10.46300/9108.2020.14.1
Lossless compression is crucial in the remote transmission of large-scale medical image and the retainment of complete medical diagnostic information. The lossless compression method of medical image based on differential probability of image is proposed in this study. The medical image with DICOM format was decorrelated by the differential method, and the difference matrix was optimally coded by the Huffman coding method to obtain the optimal compression effect. Experimental results obtained using the new method were compared with those using Lempel–Ziv–Welch, modified run–length encoding, and block–bit allocation methods to verify its effectiveness. For 2-D medical images, the lossless compression effect of the proposed method is the best when the object region is more than 20% of the image. For 3-D medical images, the proposed method has the highest compression ratio among the control methods. The proposed method can be directly used for lossless compression of DICOM images.
无损压缩对于远程传输大规模医学图像和保留完整的医学诊断信息至关重要。提出了一种基于图像差分概率的医学图像无损压缩方法。采用差分方法对DICOM格式的医学图像进行去相关处理,并采用霍夫曼编码方法对差分矩阵进行优化编码,以获得最佳压缩效果。实验结果与Lempel-Ziv-Welch、改进的行长编码和块比特分配方法进行了比较,验证了新方法的有效性。对于二维医学图像,当目标区域占图像的20%以上时,所提方法的无损压缩效果最好。对于三维医学图像,该方法在控制方法中具有最高的压缩比。该方法可直接用于DICOM图像的无损压缩。

Physiologic regulation of extracellular matrix (ECM) in articular cartilage tissue is controlled by cellular and molecular mechanisms which are not fully understood. It has been observed that the synthesis of the ECM structural molecules, glycosaminoglycan and collagen are promoted by growth factors such as IGF-1 and TGF-β. Concomitant ECM degradation is promoted by a variety of cytokines such as IL-1. The clinical need for reparative therapies of articular cartilage is linked with its poor intrinsic healing capacity. The following modelling approach was applied to engineered cartilage as a platform for exploring cartilage biology and to introduce a predictive tool as a bioinformatic support system supporting regenerative therapies. Systems biology was adapted through a mathematical framework producing a computational intelligence paradigm to explore a controlled phasic regulatory influence of the inhibition and production of ECM biomolecules. Model outcomes describe a steady synthesis of ECM as a dependence on a cyclic influence of the catabolic action of proteases and anabolic action of growth factors. This relationship is shown quantitatively in a governing harmonic equation representing the simplified biological mechanisms of biomolecule homeostasis.

关节软骨组织细胞外基质(ECM)的生理调控是由细胞和分子机制控制的,但目前尚不完全清楚。研究发现,生长因子如IGF-1和TGF-β促进了ECM结构分子、糖胺聚糖和胶原蛋白的合成。伴随的ECM降解由多种细胞因子如IL-1促进。临床对关节软骨修复治疗的需求与关节软骨较差的内在愈合能力有关。以下建模方法应用于工程软骨,作为探索软骨生物学的平台,并引入预测工具作为支持再生治疗的生物信息学支持系统。系统生物学通过产生计算智能范式的数学框架进行了调整,以探索ECM生物分子的抑制和产生的受控相位调节影响。模型结果描述了ECM的稳定合成依赖于蛋白酶的分解代谢作用和生长因子的合成代谢作用的循环影响。这种关系在代表生物分子稳态的简化生物学机制的控制调和方程中定量地显示出来。
