Indonesia still used diesel engine to produce electricity in isolated area because of its efficiency. Many attempts were made to keep it efficient, one of them by monitor and fix the problem quickly. Current monitoring system can inform if the engine get any problem, the expert then analyze and give advice to fix the problem. In the other side, lack of expert inhibit decision making process. A frame-based expert system for diesel engine fault diagnosis has been proposed since its flexibility to accommodate various problem based on its structure. This paper discusses inference process, overall structure and knowledge representation to resolve the problem. This system is utilizing CLIPS as the back-end to inference the knowledge.
印度尼西亚在偏远地区仍然使用柴油发电,因为它的效率很高。为了保持它的效率,人们做了许多尝试,其中之一是通过监控和快速解决问题。现有的监测系统可以在发动机出现任何问题时通知专家,然后进行分析并给出解决问题的建议。另一方面,专家的缺乏抑制了决策过程。提出了一种基于框架的柴油机故障诊断专家系统,由于其结构灵活,可适应各种问题。本文从推理过程、总体结构和知识表示等方面进行了探讨。本系统利用CLIPS作为后端对知识进行推理。

Pushing regularity constraint on high utility itemsets mining 高效用项集挖掘的推规则约束
Komate Amphawan, A. Surarerks
High utility itemsets mining (HUIM) is an interesting topic in data mining which can be applied in a wide range of applications, for example, on retail marketing-finding sets of sold products giving high profit, low cost, etc. However, HUIM only considers utility values of items/itemsets which may be insufficient to observe buying behavior of customers. To address this issue, we here introduce an approach to add regularity constraint into high utility itemsets mining. Based on this approach, sets of cooccurrence items with high utility values and regular occurrence, called high utility-regular itemsets (HURIs), are regarded as interesting itemsets. To mine HURIs, an efficient single-pass algorithm, called HURI-UL, is proposed. HURI-UL applies concept of remaining and overestimated utilities of itemsets to early prune search space (uninteresting itemsets) and also utilizes utility list structure to efficiently maintain utility values and occurrence information of itemsets. Experimental results on real dataseis show that our proposed HURI-UL is efficient to discover high utility itemsets with regular occurrence.
高效用项集挖掘(High utility itemsets mining, HUIM)是数据挖掘领域的一个有趣的研究课题,具有广泛的应用前景,如在零售营销中寻找高利润、低成本的已售产品集等。然而,HUIM只考虑物品/物品集的效用值,可能不足以观察顾客的购买行为。为了解决这个问题,我们在这里引入了一种在高效用项集挖掘中添加规则约束的方法。基于这种方法,具有高实用价值且经常出现的协同项集(称为高实用-规则项集)被视为感兴趣的项集。为了挖掘huri,提出了一种高效的单遍算法——HURI-UL。HURI-UL将项目集剩余效用和高估效用的概念应用于早期修剪搜索空间(无兴趣项目集),并利用效用列表结构有效地维护项目集的效用值和出现信息。在实际数据上的实验结果表明,本文提出的HURI-UL算法能够有效地发现具有规律性的高效用项集。

English to Japanese spoken lecture translation system by using DNN-HMM and phrase-based SMT 基于DNN-HMM和基于短语的SMT的英语到日语口语讲座翻译系统
Norioki Goto, Kazumasa Yamamoto, S. Nakagawa
This paper presents our scheme to translate spoken English lectures into Japanese that consists of an English automatic speech recognition system (ASR) that utilizes a deep neural network (DNN) and an English to Japanese phrase-based statistical machine translation system (SMT). We utilized an existing Wall Street Journal corpus for our acoustic model and adapted it with MIT OpenCourseWare lectures whose transcriptions we also utilized to create our language model. For the parallel corpus of our SMT system, we used TED Talks and Japanese News Article Alignment Data. Our ASR system achieved a word error rate (WER) of 21.0%, and our SMT system achieved a 3-gram base bilingual evaluation understudy (BLEU) of 16.8 for text input and 14.6 for speech input, respectively. These scores outperformed our previous system : WER = 32.1% and BLEU = 11.0.

Relation between EMG signal activation and time lags using feature analysis during dynamic contraction 动态收缩过程中肌电信号激活与时间滞后的关系
N. Ahamed, O. Altwijri, S. A. M. Matiur Rahaman, N. Ahmed, M. Alqahtani, K. Sundaraj
This study examined the effects of electromyographic (EMG) signals from Biceps Brachii (BB) muscle on the root mean square (RMS)-time relationships during dynamic contraction. Ten healthy and right hand dominated male subjects were volunteered for the experiments. The RMS features were extracted from the corresponding EMG signals (amplitude of the full wave EMG) for 10 seconds in 5 minutes intervals between each trial. Ten seconds (or 10000 ms) were divided into 4 time lags to identify the muscle activity and relationship between EMG and time using different statistical analysing techniques, such as mean, regression analysis, correlation, ANOVA, and coefficient of variation (CoV) for muscle activity variation. The results shows that large positive linear association between EMG and endurance time where the points are close to the linear trend line (R squared = 0.93 and F-ratio = 453.1). Signal steadiness is better during last time lags (1.66% during 7501-10000 ms) compared to initial time duration (10.35% during 0-2500 ms).
本研究检测了肱二头肌(BB)肌电图(EMG)信号对动态收缩时均方根时间关系的影响。10名健康且以右手为主的男性受试者自愿参加实验。每隔5分钟从相应的肌电信号(全波肌电信号振幅)中提取10秒的均方根特征。将10秒(或10000毫秒)分为4个时间滞后,使用不同的统计分析技术,如肌肉活动变化的均值、回归分析、相关分析、方差分析和变异系数(CoV),识别肌肉活动以及肌电图与时间的关系。结果表明,肌电图与耐力时间之间存在较大的线性正相关关系(R方= 0.93,f比= 453.1)。与初始时间间隔(0-2500 ms期间的10.35%)相比,最后时间滞后期间的信号稳定性更好(7501-10000 ms期间的1.66%)。

Incorporating text information on presentation slides for spoken lecture retrieval 结合演讲幻灯片的文本信息,用于口语讲座检索
Kosuke Yamauchi, Tomoyoshi Akiba
In recent years, multimedia contents, such as audio and video data, have been increasing, and the search techniques for them are needed. Spoken content retrieval (SCR), which retrieves speech data using their transcription generated by an automatic speech recognition (ASR) system, has been widely studied. One of the challenges in SCR is how to deal with ASR errors found in the transcription. To alleviate the error effects, we propose to use the presentation slides along with the ASR results in the case of the retrieval targeting presentations taken place in an academic conference. We present three methods of using the presentation slides. We performed experiments on NTCIR-11 slide segmentation data set. In the results, we observed the significant improvement on the all proposed methods.

Objective assessment and quantification of pearl quality by spectral-spatial features 利用光谱空间特征客观评价和定量珍珠质量
Yuki Ota, Hiroshi Higashi, S. Nakauchi
Quality of pearl is subjectively and visually assessed by experts. The experts assess pearls from various factors such as size, shape, gloss, color, and so on. Among these factors, body color, interference color, glossiness and thickness of nacre of pearl are the most important for the quality of pearls. This study proposes a method that assesses and quantifies each factor of the pearl quality by using optical measurement. The spectral and spatial features were extracted from spectral imaging measurements. Quantitative values for each factor are estimated from the spectral and spatial features. We compared the estimated quantitative values with experts' evaluations. The result shows that the proposed method can accurately predict the experts' evaluations.

Automated detection of spiculated masses using integrated method based on active contour 基于活动轮廓综合方法的毛刺体自动检测
Piyatragoon Boonthong, Suwanna Rasmequan, Annupan Rodtook, K. Chinnasarn
Medical image processing techniques have been used for breast cancer diagnosis research in the last few years. The spiculated mass is a factors that indicates underlying malignancy. This proposes an automatic algorithm for speculated mass detection. The algorithm comprises efficient image processing steps. Removing the pectoral muscles and digital mammography background leaves only the fatty tissue and breast masses that are early priorities of this algorithm. Then automatic extraction of ROI is required. The proposed polynomial improves the quality of the ROI in term of intensity contrast. The initial models of active contour based on GGVF are constructed using Radon transform and the hierarchical clustering. The final shape of active model represents the irregular shape of spiculation. The numerical tests employing images from the digital database for screening mammography show good accuracy of our proposed algorithm for detecting spiculated masses.
在过去的几年里,医学图像处理技术已经被用于乳腺癌的诊断研究。棘状肿块是提示潜在恶性肿瘤的一个因素。提出了一种推测质量检测的自动算法。该算法包含高效的图像处理步骤。去除胸肌和数字乳房x光背景,只留下脂肪组织和乳房肿块,这是该算法的早期优先事项。然后需要自动提取ROI。所提出的多项式在强度对比方面提高了ROI的质量。利用Radon变换和分层聚类方法,建立了基于GGVF的活动轮廓初始模型。活动模式的最终形状代表了不规则的毛刺形状。数值试验表明,本文提出的算法对乳腺肿块的检测具有良好的准确性。

A study on the efficiency of creating stories by the use of templates 使用模板创建故事的效率研究
Seiya Kawagoe, Miki Ueno, H. Isahara
The efficiency of creating stories by writers is very important for publishing a plentiful supply of products in the market. Although there are only a handful of matured writers, little research has been reported regarding a computational approach to support the creation of stories. In order to help amateur writers with creating well organized stories, we propose a newly developed system based on the four templates. In this paper, we constructed a system referring to the previous study and presented the outline of the novel system by utilizing templates. To confirm the efficiency of templates, user experiments were performed.

作者创作故事的效率对于在市场上出版大量产品非常重要。尽管成熟的作家屈指可数,但关于用计算方法来支持故事创作的研究却很少。为了帮助业余作家创作出组织良好的故事,我们在这四个模板的基础上提出了一个新的开发系统。在本文中,我们参考前人的研究构建了一个系统,并利用模板给出了新系统的轮廓。为了验证模板的有效性,进行了用户实验。从实验中,我们发现人物的背景是创造有吸引力的故事的最重要因素。最后,讨论了开发本系统的需求。

Although there are only a handful of matured writers, little research has been reported regarding a computational approach to support the creation of stories. In order to help amateur writers with creating well organized stories, we propose a newly developed system based on the four templates. In this paper, we constructed a system referring to the previous study and presented the outline of the novel system by utilizing templates. To confirm the efficiency of templates, user experiments were performed. From the experiments, we found that the backgrounds of characters are the most significant ingredient for the creation of attractive stories.
