A Method for Navigation of Autonomous Vehicles in Outdoor Environment through Stereo Correspondence

The authors have discussed a methodology of using stereo matching (stereo correspondence) to generate a disparity map of a scene whose images were taken through two cameras which are setup in a stereo vision configuration. Some of the algorithms which can be used to for this purpose are discussed. The generated disparity map is segmented to identify closest obstacles. Based on this data a kalman filter based path planning algorithm is suggested to facilitate the movement of the robot from a source point to a destination
Adversarial Validation Approach to Concept Drift Problem in Automated Machine Learning Systems

In user targeting automation systems, concept drift in input data is one of the main challenges. It deteriorates model performance on new data over time. Previous research on concept drift mostly proposed model retraining after observing performance decreases. However, this approach is suboptimal because the system fixes the problem only after suffering from poor performance on new data. Here, we introduce an adversarial validation approach to concept drift problems in user targeting automation systems. With our approach, the system detects concept drift in new data before making inference, trains a model, and produces predictions adapted to the new data. We show that our approach addresses concept drift effectively with the AutoML3 Lifelong Machine Learning challenge data as well as in Uber's internal user targeting automation system, MaLTA.
Question Asking During Tutoring and in the Design of Educational Software

Question asking has had a rather controversial status in the fields of cognitive science and education. Intelligent tutoring systems have imported models in artificial intelligence that formally specify the knowledge representations, problem-solving methods, reasoning heuristics, question-answering procedures, and cognitive mechanisms that underlie effective teaching. An ideal interface would minimize communication barriers between computer systems and human users. Human–computer interfaces can be designed in a manner that minimizes reliance on the computer interpreting or producing lengthy text in natural language. Successful communication between a computer and user would require a “mixed initiative dialogue”. The designer of a mixed initiative dialogue facility would benefit from a psychological theory of question asking that is grounded in empirical data.
Extent and barriers of Collaboration among Administrators in Teachers’ Professional Development Program

The study aims to determine the extent of collaboration among school administrators in the Teachers’ Professional Development Program in terms of sense of belonging; networks, feelings of trust and safety; reciprocity; participation; citizen power/proactivity; values;, norms, outlook in life; and diversity. It also aims to determine any significant difference between the extent of collaboration of the school administrators when grouped according to their profile and to determine the barriers to collaboration in the Teachers’ Professional Development Program. The study utilized descriptive qualitative design and quota sampling wherein 60 administrators from 3 schools of district 5 of Quezon City participated. For public secondary schools In-Service Training got the highest percentage (100%) in terms of Teachers’ Professional Development Program. For the factors on the extent of collaboration among school administrators, only citizen power/proactivity got a weighted mean of 2.96 which is below 3.50 and interpreted as “High Extent” while all other factors got a weighted mean higher than 3.50 and interpreted as “Very High Extent”. There was also no significant difference between the extent of collaboration of school administrators when they are grouped according to their length of service (p-value=0.248); educational attainment (p-value=0.088); and position/rank (p-value=0.265). Meanwhile, the first three in rank in barriers to collaboration in the Teachers’ Professional Development Program are dissemination of information and proper coordination, resources/finances and time management, and lastly, commitment and decision making.
Code Refactoring from OpenMP to MapReduce Model for Big Data Processing

In the multi-core era, much software has been developed using parallel programming technology, such as OpenMP, to take full advantage of the CPU cores. Nevertheless, in the era of big data, ubiquitous systems have enabled data collection on an unprecedented scale, the existing computing power and storage capacity can no longer effectively satisfy the needs of big data processing. MapReduce is a parallel programming model in cloud computing, which provides a new way to cope with the problem of OpenMP program's resource limitations for processing big data. In order to enable the legacy OpenMP-based program to take advantage of the virtue of cloud computing for processing big data, it is worth studying how to refactor it into MapReduce model. A detailed approach for refactoring OpenMP to MapReduce is proposed, and a prototype tool O2MR was developed in this paper. Two experiments show that the refactoring approach is efficient and the tool is helpful to refactoring process. In addition, the program execution times before and after refactoring were compared by five data sets, and the results demonstrate that the refactored program has better performance than the original in the face of big data, and the performance of the refactored program will be better as the amount of data increases.
ATHWEL: Gamification Supportive Tool for Special Educational Centers in Sri Lanka

Learning Disability is a neurologically-based problem which involves in learning basic skills such as reading, writing and math. Intellectual Disability is characterized by below-average intelligence. Children with Intellectual Disability can do and learn new skills, but they learn them more slowly than average children of their age. Game-based learning is an effective way of getting learners actively involved in educational activities. Educating children with Intellectual Disability is a challenging process. They usually learn and progress more slowly than average children. Such children may have issues with motivation and interest in education; the use of Gamification approach becomes important as a motivational and interested affordance. A prototype desktop Gamification Supportive Tool called “ATHWELA” is proposed which operates through Assistive Technology. Assistive technology can be a device or a service that is used to increase, maintain, or improve functional capabilities of individuals with disabilities. Children with Intellectual Disability can be less interested in Mathematics, some can be not good in reading and some can be not good in writing. ATHWELA is targeting at increasing, maintaining, or improving these three points and ATHWELA can be used in special education classrooms as a tool of gratification and extrinsic motivation. Points and rewards will be presented as the motivational technique. The main objective of our research is to help children with Intellectual Disability with their primary educational skills with less effort and in an interactive way and this prototype desktop application is developed in the Sinhala language because the Sinhala is the mother-tongue of Sri Lanka. In addition, it has used Machine Learning and Image Processing techniques to improve the educational skills of children with Intellectual Disability.
A Study on The Effect of Middle-aged Women’s Choir Experiences on Resilience

본 논문은 중년여성의 합창활동 경험이 닥쳐진 어려움을 다시 극복하려는 회복탄력성에 미치는 영향에 대한 연구이다. 연구는 문헌연구와 더불어 설문을 통해 이루어졌고 연구대상은 서울시 25개 구에 위치한 구립합창단에서 활동하는 중년여성으로 만 40세부터 만 64세까지의 연령을 대상으로 제한하였다. 서울시 25개 구의 구립합창단 전수를 조사하여 총 429개의 설문지를 수거하였으며, 그 중 중년의 나이에 해당하는 설문지 404개에 대하여 SPSS 21.0을 사용하여 분석하였다. 본 논문의 연구결과를 바탕으로 볼 때 중년여성의 합창단에 대한 만족도는 회복탄력성에 가장 큰 영향을 미치며, 만족도가 높을수록 다른 영역에도 긍정적인 결과가 있음을 확인할 수 있었다. 따라서 합창단에 대한 만족도가 매우 중요하며 이를 향상시키기 위해 합창단에 대한 자부심과 단원과 반주자, 지휘자의 관계 향상에도 다각적인 노력과 관심이 필요함을 알 수 있다. 본 연구에서 실시한 합창활동을 하는 중년여성에 대한 연구를 통해 회복탄력성 긍정적인 영향을 주고 나아가 중년여성 뿐 아니라 우리사회 삶의 만족도가 향상되는 것에 기여하기를 바란다.This paper was a study on the effect of middle-aged women’s choir experiences on resilience and the ability to overcome adversity. The research was conducted through questionnaires, along with a study of the related literature. The subjects of the study were middle-aged women who were active in municipal choirs located in 25 districts of Seoul. A total of 429 questionnaires were collected after surveying the total number of municipal choirs across 25 districts of Seoul. Among these, 404 questionnaires from middle-aged women were analyzed using SPSS 21.0. Based on the results of this study, the satisfaction derived from choir experiences in middle-aged women had the greatest impact on resilience, and it was further shown that the higher the satisfaction, the more positive the results in other areas. Thus, satisfaction from choir experiences was highly important to members, and improving the shared pride of the choir and the relationship between members, accompanists, and conductors therefore requires attention and various efforts to be made. We hope that this study’s research on middle-aged women’s choral activities will have a positive impact on resilience, and contribute to improving not only the satisfaction of middle-aged women, but also of our society.

Planning a Domain-specific Electronic Dictionary for the Mathematical Field of Graph Theory: Definitional Patterns and Term Variation

We plan to create an electronic dictionary for the mathematical field of graph theory. The dictionary should help students to improve their usage of the mathematical terminology. Besides the alphabetical access, the dictionary will also provide thematic, onomasiological access; it will contain lemmas in German and English, related terms and equivalence statements. Presently, such a dictionary does not exist. The dictionary basis is formed by two corpora composed of textbooks, scientific papers and lecture notes, containing all the texts the students use in their graph theory course in German and English. In the current pre- lexicographic stage, our focus is on relations between terms and on patterns used in the corpus to express them. We collect the definition patterns in the corpus and plan to use them for term extraction. Thereby, we can extract the semantic relations at the same time. In this paper we explore in particular the synonymy relations from an orthographical, morphological and syntactic perspective and draw conclusions for data acquisition. It might be possible to apply our extraction methods later for creating dictionaries in other mathematical domains.

Critical Discourse Analysis on “We are the World 25 for Haiti” Song Lyrics

This research aims in analyzing a song entitled “We are the World 25 for Haiti”. This song was first introduced by Michael Jackson in 1985 named “We are the World 1985” when he made collaboration with other musicians for USA for Africa (United Support of Artists for Africa). The single was intended as a charity single to raise funds for famine relief efforts in Ethiopia who have suffered political instability and disaster drought in 1984-1985. Then, this song was chosen to be used for collecting funds in rehabilitating Haiti after the enormous earthquake. This paper focuses on the composer’s attitudes, the social relation among the participants, the context of the situation, and the power relation in the discourse. Theories used in this research were based on Van Dijk (2004), and Martin and Rose (2013). The lyrics are taken as the object of the research. The data were initially analyzed based on Martin and Rose (2003). The findings showed that the all types of attitude were found, they were expressing feelings, judging people’s character, and appreciating things. But one parts of judging people’s character was not found in the song lyrics. The result of the study is hoped to be beneficial for readers to have a better understanding about the Critical Discourse Analysis
Clinical outcome of 100 total knee replacements using Persona posterior stabilized knee implant- A prospective observational study

Background: Total knee arthroplasty is a well accepted treatment for managing end-stage symptomatic osteoarthritis of knee.Many designs of prostheses have evolved over a period of time with almost similar clinical outcomes.The aim of this study was to evaluate the functional outcome of total knee arthroplasty using persona posteriorly stabilized knee implant (Zimmer, Warsaw, Indiana) and to investigate the effect of pre operative range of motion of involved knee on final range of motion and to observe the trends in the post op range of motion of the knee after total knee Arthroplasty.Methods: This was a prospective, observational study involving 100 total knee replacements in 60 patients using Persona Posterior Stabilised Knee Implant system.All patients were assessed clinically and radiologically with respect to the improvement of function and range of motion of knee joint, grading of pain, daily routine activity modification and generalized wellbeing after surgery and Knee society score was calculated.Results: During the study period, 3 patients died on follow up (due to multiple comorbidities) and one patient underwent revision surgery for late infection, all of them had underwent unilateral knee replacement.Knee Society Score, and knee range of motion of 96 knees in 56 patients was assessed preoperatively and postoperatively at 3 months, 6 months, 1 year, 2 years and 3 years.There was a significant improvement in mean KSS, FS and Pain score post operatively upto 1 yr with no significant improvement thereafter.Range of motion reduced significantly 3 months post op with a significant improvement thereafter at 6 months and 1 year.Furthermore patients with less pre op ROM gained significantly more ROM than the patients with better pre op ROM.Conclusion: Persona posteriorly stabilized knee show good functional outcome at 3 years follow up period and post operative range of motion of the knee, functional score and knee society score show improving trend with significant improvement upto 1 yr.
Video Game Design and Performance Analysis Based on Reinforcement Learning

The Reinforcement Learning (RL) implement real-time decision-making behavior in uncertain environment in order to optimize overall target. RL is considered to be the paradigm of future general artificial intelligence (AI) because it is very similar to the way human thinks, which is expected to be widely used in game designing. In order to make RL algorithm perform better in video games, the model-free algorithm is used and convolutional neural network (CNN) is used in the pre-processing. In this paper, the performance of Deep Q Network (DQN) and Double Deep Q Network (DDQN) algorithms were tested and compared in the Arkanoid Game. The experiment shows that the DQN algorithm has a problem of overestimating the Q value and the DDQN algorithm can solve it well. In addition, the two algorithms are similar in terms of loss changes, but the learning effect of DDQN performs better.
Resolution Limits of Non-Adaptive Querying for Noisy 20 Questions Estimation

We study fundamental limits of estimation accuracy for the noisy 20 questions problem with measurement-dependent noise and introduce optimal non-adaptive procedures that achieve these limits. The minimal achievable resolution is defined as the absolute difference between the estimated and the true values of the target random variable, given a finite number of queries constrained by the excess-resolution probability. Inspired by the relationship between the 20 questions problem and the channel coding problem, we derive non-asymptotic bounds on the minimal achievable resolution. Furthermore, applying the Berry--Esseen theorem to our non-asymptotic bounds, we obtain a second-order asymptotic approximation to finite blocklength performance, specifically the achievable resolution of optimal non-adaptive query procedures with a finite number of queries subject to the excess-resolution probability constraint.
Identification of Patterns of Fatal Injuries in Humans through Big Data

External cause injuries are defined as intentionally or unintentionally harm or injury to a person, which may be caused by trauma, poisoning, assault, accidents, etc., being fatal (fatal injury) or not leading to death (non-fatal injury). External injuries have been considered a global health problem for two decades. This work aims to determine criminal patterns using data mining techniques to a sample of patients from Mumbai city in India.
An Adaptive Background Modelling Method Based on Modified Running Averages

Background modelling plays an important role in detecting foreground objects for video analysis. Many background subtraction methods have been proposed in the past two decades, such as Gaussian Mixture Models (GMM) and Running Averages. Since these per-pixel approaches update the background at the pixel level, they are prone to false foreground and background classifications which may results in foreground detection problems. For example, a slow moving object or one with intermittent motion may be erroneously incorporated into the background model. Also, these models typically assume a clean background image at initialization, which is difficult to achieve in real world scenario, leading to the 'bootstrapping' challenge. These issues can be addressed by using high level object tracking information as an analysis operation, and feeding back into a per-pixel model. This paper describes a method to model backgrounds using higher level knowledge of object movements derived from a robust tracker. Experimental results reveal that our method works well and outperforms state of the art background subtraction methods such as GMM and running averages in a scene with bootstrapping and intermittent object motion background modelling challenges.
