Examples of an HMS include an automobile, an airplane, and a wearable power-assist robot. The most important point related to the development of such an operational HMS is how the machine could move and cooperate with a human operator while executing a target task without adversely affecting not only the performance of the task but also the human operator's comfort. Despite the fact that the hardware systems of recent machines are well-developed, there remain many issues affecting the realization of an ideal HMS that could fully harmonize its behavior with a human because of the difficulty in treating uncertain human properties and individuals. Therefore, recent studies on HMS have addressed many related aspects, including control theory, robotics, biomechanics, human factors/ergonomics, and neuroscience as the need arises. Recent trends in the field of HMS research include a human-centric methodology and a shared control methodology, for which better computational models for task-related human motor function and/or perceptual functions are formulated based on experimental data and embodied into the control systems of automated machines. This talk provides an outline of an HMS, describes some state-of-the-art research, and invites open questions with the aim of identifying what we should/could do to achieve further innovation in the HMS field.","PeriodicalId":262942,"journal":{"name":"2016 IEEE 9th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129842488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we propose canonical representations, which are representations having the structure of rooted and ordered trees, of block tree patterns in acquiring characteristic block preserving outerplanar graph patterns. Then we give an algorithm for calculating canonical representations of block tree patterns.

Protein structure alignment, which is similar to sequence alignment, can detect the structural homology between two proteins according to their three-dimensional structures. One of the simplest yet most robust techniques for finding optimal protein structure alignment is to maximize the contact map overlap (CMO). This optimization is known as the CMO problem. We have been developing bio-inspired heuristic models using distributed modified extremal optimization (DMEO) for the CMO problem. DMEO is inspired by distributed genetic algorithms, which are known as island models. DMEO is a hybrid of population-based modified extremal optimization (PMEO) and the island model. In our previous work, we proposed a novel bio-inspired heuristic model, i.e., DMEO with different evolutionary strategies (DMEODES) to maintain population diversity. DMEODES is based on the island model; however, some of the islands, called hot-spot islands, have a different evolutionary strategy. In this paper, we propose a state-of-art heuristic model to improve the DMEO's ability to prevent evolution stagnation. The new model integrates an adaptive generation alternation mechanism in DMEO called ADMEO. To evaluate ADMEO, we used actual protein structures. Experimental results show that ADMEO outperforms DMEODES.","PeriodicalId":262942,"journal":{"name":"2016 IEEE 9th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117252854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The success of these specialized algorithms in generating music, however, depends heavily on the fitness function that is used to score the generated music and equally as important is how the fitness function is designed. Artificial intelligence in the computational composition can use certain feature set values derived from melodic analysis to serve as criteria for these fitness functions. This study explores two methods in defining the key features to be used as fitness criteria for algorithmic music generation of music that can be considered under a mix of two musical genres or hybrid-genre music. The jSymbolic tool was used to extract 101 features from musical pieces that fall under two genres. This was then reduced to a smaller feature set for use as fitness criteria. Two methods for feature reduction was explored; a decision-tree-based technique and a high-correlation-filtering technique. The study was able to confirm that each technique can be used to compose hybrid-genre music with 86% success-rate as confirmed by SVM when validated under the same dataset used in the study. This study does not claim to consistently result in a high success rate for all existing datasets.","PeriodicalId":262942,"journal":{"name":"2016 IEEE 9th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122183358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The \"portfolio\" comprises two correction methods based on a Wiener process: one uses history data for the current day and the other uses data for previous days. The error between the predicted and actual time is assumed to have a normal distribution. Portfolio theory is used to determine the optimal application of the two methods to the correction process. Simulation using actual data showed that the average error in the predicted arrival time was reduced to 4 s from 12 s when the timetable was dense. This error reduction will, for example, improve the efficiency of regenerative braking systems, in which the kinetic energy of an arriving (braking) train is electrically transmitted to a departing (accelerating) train.","PeriodicalId":262942,"journal":{"name":"2016 IEEE 9th International Workshop on Computational Intelligence and Applications (IWCIA)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126752529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
