To be more practical, the communication topologies are assumed to switch arbitrarily among a finite set of directed topologies, and each of which is only required to have a directed spanning tree. Moreover, we assume that the impulsive effects are taken into account only during the process of signal exchange. Some sufficient synchronization criteria are obtained based on an impulsive differential inequality and the average impulsive interval. We also show that these dynamical networks can attain exponential synchronization only by single impulsive control. A simple example is proposed to show the efficiency of the criteria that obtained from the theory result.","PeriodicalId":211040,"journal":{"name":"2016 Eighth International Conference on Advanced Computational Intelligence (ICACI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129274296","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}

Three key techniques are mainly discussed including the ensemble empirical mode decomposition (EEMD), the sparse multinomial logistic regression algorithm with Bayesian regularization (SBMLR) and the fuzzy least squares support vector machine (FLS-SVM). All of the features based on the EEMD are extracted from sensor data. Then, the features vectors are processed by an embedded feature selection algorithm - SBMLR, which may remarkably reduce the dimension and maintain the most discriminative information. The FLS-SVM technique is employed to deal with the reduced features and identify human activities. Experimental results show that our approach achieves an overall mean classification rate of 93.43%, which exhibits the remarkable recognition performance compared with other approaches. We conclude that the proposed approach could play an important role in human activity recognition (HAR) using wearable sensors, especially in real-time applications and large-scale dataset processing.","PeriodicalId":211040,"journal":{"name":"2016 Eighth International Conference on Advanced Computational Intelligence (ICACI)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114266232","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 purpose of the research aims to construct an Opening-Book system of Connect6 game. In this study, it develops a real system that can apply Opening-Book system of Connect6 to Kavalan. However, the method in which constructed the system is not by profession's domain knowledge, and it is constructed by numerous end games. The study collects various end games to construct positions of opening book from public competitions, including self-games. The study incorporates the previous results into the design of the tree structure of Connect6 opening: the research of Bitboard design and bitwise computing of Connect6, revised algorithm of MCTS to fit the property of sudden-death, and the experience of software development of Connect6 game. It plays an important role of developing Connect6 opening to combine the building of Opening-Book system and the search algorithm of Connect6. In addition, it can show the overall efficiency only if the search algorithm and Connect6 opening are perfect match. Hence, two methods balance the advantage and disadvantage to achieve the greatest accomplishment. The study has finished the analysis of Connect6 board and the design of Connect6 opening. Besides, it also finished the development of the Opening-Book system of Connect6 game, and attached it to the MCTS of Connect6. With the increasing of positions saving in the Connect6 opening, Kavalan already greatly reducing the time spent on opening-game.

However, due to the inherent nonlinearities and model uncertainties, motion control of such manipulators becomes extremely challenging. In this work, a hybrid framework combining Programming by Demonstration (PbD) and reinforcement learning is proposed to solve this problem. Gaussian Mixture Models (GMM), Gaussian Mixture Regression (GMR) and linear regression are used to learn the inverse kinematic model of the manipulator from human demonstrations. The learned model is used as nominal model to calculate the output end-effector trajectories of the manipulator. Two surgical tasks are performed to demonstrate the effectiveness of reinforcement learning: tube insertion and circle following. Gaussian noise is introduced to the standard model and the disturbed models are fed to the manipulator to calculate the actuator input with respect to the task specific end-effector trajectories. An expectation maximization (E-M) based reinforcement learning algorithm is used to update the disturbed model with returns from rollouts. Simulation results have verified that the disturbed model can be converged to the standard one and the tracking accuracy is enhanced.","PeriodicalId":211040,"journal":{"name":"2016 Eighth International Conference on Advanced Computational Intelligence (ICACI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129276109","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}

For these reasons, many neural network algorithms have been proposed to solve kWTA. Compared with software simulations, the hardware implementation is capable of a high degree of parallelism. There are many hardware implementations that have been proposed, such as digital chips, analog chips, hybrids chips, FPGA based chips, and (non-electronic) optical chips implementation.

Motivated by the fact that the total cost of smart grid will achieve its minimal value if the state consensus among incremental costs for all generating units can be ensured, a new kind of adaptive consensus protocol is proposed to make the incremental costs of all generating units in the smart grid subject to communication uncertainties achieve consensus. It is proven that the power demand and supply of the considered power system will be balanced during the dispatch process as long as the initial power outputs of generating units are appropriately selected. This indicates that the present adaptive consensus-based dispatch strategy is applicable to solve the economic dispatch problem of smart grid subject to communication uncertainties.","PeriodicalId":211040,"journal":{"name":"2016 Eighth International Conference on Advanced Computational Intelligence (ICACI)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115085657","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 technique proceeds by replacing fully-connected layers with so-called Kronecker fully-connected layers, where the weight matrices of the fully-connected layers are approximated by linear combinations of multiple Kronecker products of smaller matrices. Just as the Kronecker product is a generalization of the outer product from vectors to matrices, our method is a generalization of the low rank approximation method for fully-connected layers. We also use combinations of different shapes of Kronecker product to increase modelling capacity. Experiments on SVHN, scene text recognition and ImageNet dataset demonstrate that we can achieve 10x reduction of number of parameters with less than 1% drop in accuracy, showing the effectiveness and efficiency of our method.","PeriodicalId":211040,"journal":{"name":"2016 Eighth International Conference on Advanced Computational Intelligence (ICACI)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117167531","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}
