The paper presents the results of regression analysis of specially designed dataset. The students from the second to fourth year of the Novosibirsk State Technical University have passed testing procedure, among them 123 men and 68 women at the age from 18 to 23 years. The presented dataset contains the results of eight different tests. We designed this set of psychometric tests for implementing "Learner model". The "Learner model" is an important component of personal educational environment of a university. For implementing the "Learner model", we preprocess testing data and create regression models. The method of regression analysis allows exploring the most significant predictors affecting academic performance. As a result, the most significant predictors are "conscientiousness" and "behavior inhibition system". The same predictors are significant for exploring interaction effects with categorical predictors "modality", "style of reaction on changes", "gender". We also explored combinations of psychometric characteristics for finding their influence on academic problems. For this reason, we divided students into two categories, considering their academic performance. Then, we build a logistic regression model.
本文介绍了对专门设计的数据集进行回归分析的结果。新西伯利亚国立技术大学二年级至四年级的学生已经通过了测试程序,其中123名男性和68名女性,年龄在18岁至23岁之间。所呈现的数据集包含八个不同测试的结果。我们为实施“学习者模式”而设计了这套心理测量测试。“学习者模式”是高校个人教育环境的重要组成部分。为了实现“学习者模型”,我们对测试数据进行预处理并创建回归模型。回归分析的方法可以探索影响学习成绩的最显著的预测因素。结果表明,“责任心”和“行为抑制系统”是最显著的预测因子。同样的预测因子在探索与分类预测因子“模态”、“对变化的反应方式”、“性别”的交互作用方面具有显著性。我们还探讨了心理测量特征的组合,以发现它们对学术问题的影响。因此,我们根据学生的学习成绩将他们分为两类。然后,我们建立了一个逻辑回归模型。

Plasmonic nanostructures with local temporal response: a platform for time-varying photonics 具有局部时间响应的等离子体纳米结构:时变光子学的平台

Time-varying media open up unprecedented abilities for controlling electromagnetic fields. This is due to novel forms of light-matter interactions that arise when one of the optical parameters of the medium is abruptly switched in time. The latter means that the switching time is shorter than the period of wave oscillations. This requirement makes it challenging to implement time-varying materials suitable for applications in the optical spectral range. This work is devoted to the development of an approach for implementing time-varying media with a large depth and speed of modulation of the refractive index. We exploit a system, consisting of plasmonic antennas coupled to nonlinear material with epsilon-near-zero (ENZ) properties. Hybrid plasmonic-ENZ structures modulated by pulsed laser excitation have been recently proposed as a promising platform for time-varying photonics. However, the optical response of plasmonic components is typically slow, on the order of 10-100 fs. This stems from the long lifetime of plasmonic excitations. Here, we propose a mechanism that allows one to achieve an ultrashort, less than 1 fs, plasmon lifetime. The mechanism is based on reducing of the spectral dispersion of the real part of permittivity. For this purpose, we used titanium oxynitride (TiOxNy), which represents a plasmonic material with tunable optical properties. We synthesized a series of TiOxNy thin films using various parameters of magnetron sputtering. This allowed us to achieve a unique behavior, such as broadband flat dispersion of the dielectric function in the near-infrared range. Under these conditions, the optical response becomes local in time. The results of this study provide novel opportunities for designing and practical implementation of photonic devices based on time-varying media.
时变介质为控制电磁场开辟了前所未有的能力。这是由于当介质的一个光学参数在时间上突然切换时,产生了新型的光-物质相互作用。后者意味着开关时间短于波的振荡周期。这一要求使得在光学光谱范围内实现适合应用的时变材料变得具有挑战性。这项工作致力于发展一种实现具有大深度和调制速度的折射率时变介质的方法。我们开发了一个系统,由等离子体天线耦合到具有epsilon-near-zero (ENZ)特性的非线性材料。由脉冲激光激发调制的等离子体- enz混合结构是时变光子学研究的一个很有前途的平台。然而,等离子体元件的光学响应通常很慢,在10-100 fs的数量级上。这源于等离子体激发的长寿命。在这里,我们提出了一种机制,允许人们实现超短,小于1秒,等离子体寿命。其机理是基于介电常数实部色散的减小。为此,我们使用了氧氮化钛(TiOxNy),这是一种具有可调谐光学特性的等离子体材料。我们利用不同的磁控溅射参数合成了一系列的TiOxNy薄膜。这使我们实现了一种独特的行为,如在近红外范围内宽带平色散的介电函数。在这些条件下,光响应在时间上变成局部的。本研究结果为时变介质光子器件的设计和实际实现提供了新的机会。

The paper is devoted to the short-term travel time prediction of individual connected vehicles in a regulated road network with adaptive control of traffic lights. The estimation of the total travel time combines both the travel time along road network links, obtained by a neural network model, and the waiting time at regulated intersections. At the first stage, it is proposed to use the model based on a neural network to estimate the travel time along the road links of the transportation network. At the second stage, the phase of the traffic light is predicted using the adaptive control method. Finally, the waiting time at the intersection is calculated based on the predicted arrival time of the vehicle at the intersection and the duration of the traffic light phase. Experimental results in a microscopic simulation environment allow us to conclude that the proposed approach outperforms baseline methods in terms of the mean absolute error criterion.

A method is proposed for passive protection of a surveillance camera video from a video fragment deletion attack. The method is based on the construction of local features for the samples of two consecutive frames, followed by a multilayer neural network classification. Post-processing and calculation of statistics based on the results of the classification make it possible to decide whether a given pair of frames is sequential or a number of frames were cut between them. Experiments show the efficiency of detecting the fact of a fragment removal even from stationary scenes, when such a deletion is visually imperceptible.
提出了一种被动保护监控摄像机视频免受视频片段删除攻击的方法。该方法基于对连续两帧的样本进行局部特征构建,然后进行多层神经网络分类。基于分类结果的后处理和统计计算使得确定给定的一对帧是连续的还是在它们之间剪切了许多帧成为可能。实验表明,即使从静止的场景中检测到片段删除的事实,当这种删除在视觉上是不可察觉的。

Automatic selection of keyphrases (keywords) is a major challenge to finding and systematizing scholarly documents. This paper investigates the efficiency of using titles of scientific papers as additional information for keyphrase generation. We propose an approach to multi-task fine-tuning the BART model using control codes1. It is shown that the suggested approach can improve the performance of BART for the task of keyphrase generation. In some cases, the presented model outperforms state-of-the-art models for keyphrase extraction. Moreover, the results have demonstrated that multitask fine-tuning also increases the performance of title generation.

Classification of plant component on image histological sections is critical for determining non-compliance type of undeclared additiveand further action for technologist, or other responsible person. However, this task is often challenging due to the absence of professional histologists or non-compliance with the conditions of microstructural analysis and also the subjective criteria for evaluation. In this study, we propose a machine learning model that automatically classifies the plant component on images histological sections. Our model uses a convolutional neural network to identify regions of plant components, then aggregates those classifications to infer predominant and minor plant components on histological sections image. We evaluated our model on an independent set of 95 images histological sections. It achieved a kappa score of 0.525 and an agreement of 66.6% with three histologists for classifying the predominant plant component, slightly higher than the inter-histologists kappa score of 0.485 and agreement of 62.7% on this test set. All evaluation metrics for our model and the three histologists were within 95% confidence intervals of agreement.
图像组织学切片上植物成分的分类对于确定未申报添加剂的不合规类型以及技术人员或其他负责人的进一步行动至关重要。然而,由于缺乏专业的历史学家或不符合微观结构分析的条件和主观评价标准,这项任务往往具有挑战性。在这项研究中,我们提出了一种机器学习模型,可以自动对图像组织切片上的植物成分进行分类。我们的模型使用卷积神经网络来识别植物成分的区域,然后汇总这些分类来推断组织学切片图像上的主要和次要植物成分。我们在一组独立的95张图像组织学切片上评估了我们的模型。kappa评分为0.525,与3位组织学家对植物主要成分分类的一致性为66.6%,略高于该测试集的组织学家间kappa评分0.485,一致性为62.7%。我们的模型和三位历史学家的所有评价指标都在95%的置信区间内一致。

One of the trends in the development of information technologies and artificial intelligence is intelligent assistants in the form of chatbots or voice assistants, which are actively beginning to be implemented in various domains. In this paper, the modeling and software implementation of a chatbot to support technical personnel in diagnosing aircraft malfunctions are considered. The models of the dialog, elements of the knowledge base implementation, as well as an example of its operation, are described. The constructed models are considered as content ontological patterns and describe the object of the study, the malfunction, and the relationships between the signs of the malfunction and its causes. These templates are used in the design of a knowledge base, containing logical rules presented in the form of decision tables of a special type. The novelty of the proposed solution is the use as a methodological basis of the principles of model-driven development in the context of creating problem-specific virtual assistants.

Colorization task consists of acquiring a full-color RGB image from grayscale image or a sketch. Article is concerned with the task of colorizing grayscale cartoon images and image sequences using neural networks. Efficiency of an existing prototype algorithm is reviewed with different modifications, as well as different combinations of loss functions. A new neural network loss function is proposed. It is based on a hypothesis that specifics of cartoons, such as clear object boundaries and color consistency within those boundaries can be used to improve colorization quality. Proposed loss function uses segmentation of cartoon images in the bilateral space, and minimizes difference between closest found segments and inside each segment, thus bringing closer predicted colors within the segment and between neighboring segments. Quantitative and qualitative experiments are conducted on efficiency as well as generalization ability of modified prototype algorithm with proposed loss function. Quantitative experiments consisted of measuring PSNR, LPIPS, MSE in Lab color space and CC, while qualitative focused on comparing temporal consistency, quality of colorization and quality of generalization.
着色任务包括从灰度图像或草图中获取全彩色RGB图像。本文研究了利用神经网络对灰度卡通图像和图像序列进行着色的问题。通过不同的修改以及不同的损失函数组合,对现有原型算法的效率进行了评价。提出了一种新的神经网络损失函数。它基于一个假设,即卡通的特定特征,如清晰的对象边界和这些边界内的颜色一致性,可以用来提高着色质量。所提出的损失函数在双边空间中对卡通图像进行分割,并将最接近的发现段之间和每个段内的差异最小化,从而使段内和相邻段之间的预测颜色更接近。采用所提出的损失函数对改进的原型算法进行了效率和泛化能力的定量和定性实验。定量实验包括测量Lab色彩空间的PSNR、LPIPS、MSE和CC,定性实验主要比较时间一致性、着色质量和泛化质量。
