In this paper, we proposes a man-machine interface design for fault diagnosis system with inter-node search method in a Petri net model. First, complicated fault cases are modeled as the Petri net graph expressions. Next, to find out causes of the faults on which we focus, a Petri net model is analyzed using the backward reasoning of transition-invariance in the Petri net. In this step, the inter-node search method algorithm is applied to the Petri net model for reducing the range of sources in faults. Finally, the proposed method is applied to a fault diagnosis of a refrigeration system to confirm the validity of the proposed method.

본 논문에서는 최근 대두되고 있는 심층신경망 압축 연구에서 가중치 공유와 관련하여 심층신경망 모델 압축방법 Inter-Layer Kernel Prediction을 제안한다. 제안 방법은 영상 압축에서 사용되는 프레임 간 prediction 방법을 응용한 컨볼루션 신경망 가중치 공유 및 모델 압축 방법이다. 본 논문은 레이어 간 유사한 kernel들이 존재한다는 것을 발견하고 이를 기반으로 Inter-Layer Kernel Prediction을 사용하여 기존 모델 가중치를 보다 더 적은 비트로 표현하여 저장하는 방법을 제안한다. 제안 방법은 CIFAR10/100으로 학습된 ResNet에서 약 4.1 배의 압축률을 달성했으며 CIFAR10으로 학습된 ResNet110에서는 오히려 기존 Baseline 모델에 비해 0.04%의 성능 향상을 기록했다.

Visual object tracking is one of the key tasks in computer vision. Robust trackers should address challenging issues such as fast motion, deformation, occlusion and so on. In this paper, we therefore propose a visual object tracking method that exploits inter-frame correlations of convolutional feature maps in Convolutional Neural Net (ConvNet). The proposed method predicts the location of a target by considering inter-frame spatial correlation between target location proposals in the present frame and its location in the previous frame. The experimental results show that the proposed algorithm outperforms the state-of-the-art work especially in hard-to-track sequences.

Today, Web Services is very well-known as a middle-ware that can inter-communicate between many different program languages. This paper test web services by implementing two different web services platforms which are MS .NET based server and Apache AXIS based client. Those platforms have different data structure/process, and they could not give the developer seamless data compatibility through web services. However we confirmed that handling data, by some data transforming rules, web services can successfully inter-communicate between MS .NET based server and Apache AXIS based client.

"최근 InterNet(국제학술정보망)에 대한 관심이 크게 증가하고 있다. 인터넷은 UNIX를 기본으로 PC를 통한 온라인 이용자들을 DIALOG와 같은 정보서비스망에 연결시켜 주는 국제적인 정보통신 네트워크이다. 국제전화료보다 훨씬 저렴한 비용으로 전세계의 다양한 기관 및 개인들과 정보이용ㆍ교환 등을 할 수 있어 국내에서도 전문연구자들 뿐만 아니라 일반 개인들에게도 커다란 관심을 모으고 있다. 이에 인터넷의 일반적인 개요와 국내에서의 이용방법 등을 자세히 알아본다."

EuroNet ist eine multilinguale Datenbasis mit WordNets $f\"{u}r\;einige\;europ\"{a}ische$ Sprachen ($holl\"{a}ndisch$, italienisch, spanisch, deutsch, $franz\"{o}sisch$, tschechisch und estnisch). Die WordNets werden genauso wie das amerikanische WordNet $f\"{u}r$ Englisch (Princeton WordNet, Miller et al. 1990) in Synsets (Zusammensetzen der synonymen $W\"{o}rter$) mit grundlegenden lexikalisch-semantischen Relationen zwischen ihnen $ausgedr\"{u}ckt$ strukturiert. Jedes WordNet stellt also ein einzigartiges innersprachliches System $f\"{u}r$ die lexikalischen und konzeptuellen Relationen dar. $Zus\"{a}tzlich$ werden diese auf dem Princeton WordNet basierten WordNets (z.B. GermaNet) mit einem Inter-Linguale-Index (kurz, ILI) verbunden. $\"{U}ber$ diesem Index werden die Sprachen zusammengeschaltet, damit zu gehen ist $m\"{o}glich$, von den $W\"{o}rtern$ in einer Sprache zu den $\"{a}hnlichen\;W\"{o}rtern$ in jeder $m\"{o}glicher$ anderen Sprache. Der Index gibt auch Zugang zu einer geteilten Top-Ontologie von 63 semantischen Unterscheidungen. Diese Top-Ontologie stellt einen allgemeinen semantischen Rahmen $f\"{u}r$ aile Sprachen zur $Verf\"{u}gung,\;w\"{a}hrend$ sprachspezifische Eigenschaften in den einzelnen WordNets beibehalten werden. Die Datenbasis kann, unter anderen, $f\"{u}r$ einsprachige und multilinguale Informationsretrieval benutzt werden. In der vorliegenden Arbeit handelt sich also um eine methodologische Untersuchung der koreanisch-deutschen ILI-Verbindung zur Anwendung der auf dem EuroNet basierten lexikalischen, semantischen Datenbasis. Dabei werden einzelnen Lexeme in koreanischen, deutschen WordNets $zun\"{a}chst$ mit Hilfe der Sense-Analyse semantisch differenziert, und dann durch lexikalische und konzeptuelle Relationen(ILI) miteinander verbunden. Die Equivalezverbindungen dienen, sprachspezifische Konzepte zum ILI abzubilden. Sie werden von einem anderen Synset der moglichen Relationen aus der Euronet-Spezifikation genommen. Wenn es keinen ILI-Rekord gibt, der ein direktes Equivalenz zu einem gegebenen Konzept darstellt, kann das Konzept in der Frage $\"{u}ber$ EQ-Near-Synonymie, EQ-Hyperonymie oder EQ-Hyponymie Relationen verbunden werden.

This paper describes a fault diagnosis method by a T-invariance of Petri Net (PN). First, a complicated fault system with some failure is modeled into a PN graphic expressions. Next, the PN model is analyzed by using the backward chaining of T-invariance to find out causes of the faults. In this step, an inter-node search technique which is suggested in this paper is applied for reducing searching area in the fault system. Also, a novel idea to compose incidence matrices which have different dimension each other in PN model is proposed. As the new knowledges which is discovered newly about faults can be added easily to conventional systems, the diagnosis system will be very flexible. Finally, the proposed method is applied to the automobile fault diagnosis system to confirm the validity of the method.

Homomorphic Encryption (HE) schemes have been recently growing as a reliable solution to preserve users' information owe to maintaining and operating the user data in the encrypted state. In addition to that, several Neural Networks models merged with HE schemes have been developed as a prospective tool for privacy-preserving machine learning. Those mentioned works demonstrated that it is possible to match the accuracy of non-encrypted models but there is always a trade-off in the computation time. In this work, we evaluate the implementation of CKKS HE scheme operations over the layers of a LeNet5 convolutional inference model, however, owing to the limitations of the evaluation environment, the scope of this work is not to develop a complete LeNet5 encrypted model. The evaluation was performed using the MNIST dataset with Microsoft SEAL (MSEAL) open-source homomorphic encryption library ported version on Python (PyFhel). The behavior of the encrypted model, the limitations faced and a small description of related and future work is also provided.
