Development and approbation of the improved CART algorithm version

Abstract This article considers the classification problems using the decision trees. It suggests the improved CART algorithm version called clean CART (CCART). The key feature of this algorithm is the reducing of the hardware memory for the tree storing. The main ideas of the CCART algorithm software implementation have been presented. The experimental results of comparison of the original and the presented algorithms for constructing the decision trees confirm that the proposed CCART algorithm has the stated advantage. Therefore, the proposed CCART algorithm is recommended for use in the ensembles of classifiers construction.
Packet fragmentation as data protection method in automated systems

Abstract The paper gives a detailed description of the information transfer covert channels and their main types. One of the most popular protection methods, the one with the software and the hardware applied to traffic encryption, against the information disclosure threat is considered. Experimental data obtained from the statistical analysis of the encrypted traffic and contributing into the identification of different modern info-communication services by the IP-package distribution and the time intervals between their arrival are collected and provided. A detailed classification of the information transfer covert channels is looked upon under the regulating documents in the in-formation protection sphere. An overall mechanism of a convert channel functioning in the automated systems is described. The areas to counteract the convert channels as an information disclosure threat are specified. The authors put forward a protection method employing IP fragmentation. A diagram of a pilot stand for the videoconference systems which was tested during the experiment is presented. The parameters and the characteristics of the obtained results are described. The results are analysed, and the possible applications of IP fragmentation as a method to counteract the information transfer convert channels in the videoconference systems are offered.
Methods for Efficient Deep Reinforcement Learning

Author(s): Green, Samuel Brooks | Advisor(s): Koc, Cetin K; Egecioglu, Omer | Abstract: Reinforcement learning (RL) is a broad family of algorithms for training autonomous agents to collect rewards in sequential decision-making tasks. Shortly after neural networks (DNNs) advanced, they were incorporated into RL algorithms as high-dimensional function approximators. Recently, deep RL algorithms have been used for many applications that were once only approachable by humans, e.g., expert-level performance at the game of Go and dexterous control of a high degree-of-freedom robotic hand. However, standard RL approaches are computationally, and often financially, expensive. High cost limits RL's real-world application, and it will slow research progress.In this dissertation, we introduce methods for developing efficient DNN-based RL agents. Our approaches for increasing efficiency draw upon recent developments for the optimization of DNN inference. Specifically, we present quantization, parameter pruning, parameter sharing, and model distillation algorithms that reduce the computational cost of DNN-based policy execution. We also introduce a new algorithm for the automatic design of DNNs which attain high performance while meeting specific resource constraints like latency and power. Intuition, which is backed by empirical results, states that a naive reduction in DNN model capacity should lead to a reduction in model performance. However, our results prove that by taking a principled approach, it is often possible to maintain high agent performance while simultaneously lowering the computational expense of decision-making.Finally, a policy must be evaluated on hardware, and currently, there is an explosion of non von Neumann architectures for the acceleration of neural algorithms. We analyze one such device, and we propose rigorous methods for the analysis of such devices for future applications.

Representation in incremental learning

Work focused on two areas in machine learning: representation for inductive learning and how to apply concept learning techniques to learning state preferences, which can represent search control knowledge for problem solving. Specifically, in the first area the issues of the effect of representation on learning, on how learning formalisms are biased, and how concept learning can benefit from the use of a hybrid formalism are addressed. In the second area, the issues of developing an agent to learn search control knowledge from the relative values of states, of the source of that qualitative information, and of the ability to use both quantitative and qualitative information in order to develop an effective problem-solving policy are examined.

Verbal Aggression as an Indicator of Xenophobic Attitudes in Greek Twitter during and after the Financial Crisis

We present a replication of a data-driven and linguistically inspired Verbal Aggression analysis framework that was designed to examine Twitter verbal attacks against predefined target groups of interest as an indicator of xenophobic attitudes during the financial crisis in Greece, in particular during the period 2013-2016. The research goal in this paper is to re-examine Verbal Aggression as an indicator of xenophobic attitudes in Greek Twitter three years later, in order to trace possible changes regarding the main targets, the types and the content of the verbal attacks against the same targets in the post crisis era, given also the ongoing refugee crisis and the political landscape in Greece as it was shaped after the elections in 2019. The results indicate an interesting rearrangement of the main targets of the verbal attacks, while the content and the types of the attacks provide valuable insights about the way these targets are being framed as compared to the respective dominant perceptions and stereotypes about them during the period 2013-2016.

The Role of Mother’s Communication Patterns on the Children’s Language Development

Children's language development is an important thing for early childhood development. One of the factors that can affect a child's language development is the communication of people who are closest to them, especially their mother. This study aim is to investigate the influence of the communication made by the mother of the child's language development. The research method conducted a quantitative approach. The subjects in this study were 126 mothers with kindergarten age children, who live in Surabaya. Data collection methods were done by using the scale of communication patterns and the scale of language development. The data analysis technique used in this study is a linear regression analysis using the SPSS program. The result of this study indicates that there is an influence of the mother's communication patterns on children's language development. This means that mothers who have active communication patterns with children will improve their child's language development. The results of this study are expected to provide input to parents to frequently make active and positive communication to stimulate children's language development.
Research on the Application of Fuzzy Logic to Systems Analysis and Control

Research conducted with the support of NASA Grant NCC2-275 has been focused in the main on the development of fuzzy logic and soft computing methodologies and their applications to systems analysis and control. with emphasis 011 problem areas which are of relevance to NASA's missions. One of the principal results of our research has been the development of a new methodology called Computing with Words (CW). Basically, in CW words drawn from a natural language are employed in place of numbers for computing and reasoning. There are two major imperatives for computing with words. First, computing with words is a necessity when the available information is too imprecise to justify the use of numbers, and second, when there is a tolerance for imprecision which can be exploited to achieve tractability, robustness, low solution cost, and better rapport with reality. Exploitation of the tolerance for imprecision is an issue of central importance in CW.

In this paper, we present the NUIG system at the TIAD shard task. This system includes graph-based metrics calculated using novel algorithms, with an unsupervised document embedding tool called ONETA and an unsupervised multi-way neural machine translation method. The results are an improvement over our previous system and produce the highest precision among all systems in the task as well as very competitive F-Measure results. Incorporating features from other systems should be easy in the framework we describe in this paper, suggesting this could very easily be extended to an even stronger result.
Where Are My Parents?: Information Needs of Hospitalized Children

We explore the information needs of hospitalized children by analyzing co-design prototypes created by children. We facilitated two simultaneous, yet separate co-design sessions with mixed groups including both children who had been hospitalized and siblings of children who had been hospitalized. The sessions focused on identifying information needs in the inpatient hospital setting. Our findings revealed that both hospitalized children and their siblings view information needs from multiple perspectives, including those of their parents, their physician, and of the hospitalized child themselves. Both co-design groups identified similar needs, including: communicating with people outside their room, tracking important people, and having entertainment for the hospitalized child.

Occurrence of fall and its influencing factors in elderly patients with knee osteoarthritis

ObjectiveTo investigate the occurrence and influencing factors of falls in elderly patients with knee osteoarthritis (KOA) , and provide scientific reference for the prevention of falls in elderly patients with KOA.MethodsUsing convenience sampling method, 104 elderly patients diagnosed as KOA in orthopaedic wards of four ClassⅢ Grade A hospitals in Hangzhou from November 2017 to August 2018 were selected as subjects. General Information Questionnaire, Morse Fall Scale (MFS) and the Barthel Index (BI) for Activities of Daily Living (ADL) were applied in the investigation. Single factor analysis and multiple factor Logistic regression were used to analyze the influencing factors of falls in elderly KOA patients.ResultsA total of 104 questionnaires were sent out in this study, and 95 valid questionnaires were recovered, yielding an effective recovery rate of 91.35%. The incidence of falls in elderly KOA patients was 45.26% (43/95) , of which 62.79% (27/43) had fallen twice or more. There were significant differences in knee injury history, staircase climbing and falls among elderly KOA patients (P< 0.05) . There were significant differences in the risk of falls between elderly KOA patients in whether taking drugs , whether using walking , status of self-care ability , and age (P< 0.05) . Logistic regression analysis showed that history of knee injury, frequent staircase climbing and use of walking aids were the influencing factors of falls in elderly KOA patients (OR=4.028, 25.569, 3.191; P< 0.05) .ConclusionsIn view of the influencing factors of falls in elderly KOA patients, individualized nursing measures should be taken to strengthen falls risk assessment, carry out fall prevention related education and improve patients' social support, which will help to reduce the incidence of falls and further improve patients' quality of life.Key words: Aged; Knee osteoarthritis; Falls; Influencing factors; Questionnaire survey; Morse Fall Scale; Barthel Index for Activities of Daily Living; Prevention
