In order to obtain better feature representation and classification performance, this paper proposes a Hybrid Hierarchical Extreme Learning Machine (HH-ELM) on the hierarchical thought of Hierarchical Extreme Learning Machine(H-ELM). The feature extraction part uses ELM-Based Auto-Encoder(ELM-AE) based on L1-norm regularization to optimize the hidden layer weights, and the classification part adopts Improved Tow-hidden-layer Extreme Learning Machine(ITELM). Experimental results on UCI datasets and Mnist images datasets show that HH-ELM has better classification results and robustness.","PeriodicalId":211585,"journal":{"name":"Proceedings of 2018 International Conference on Mathematics and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134501333","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 explore non-stationary reward MAB problem with limited query budget.

In order to estimate the instantaneous expected reward-cost ratio, the DUCB-BF policy averages past rewards with a discount factor giving more weight to recent observations. Theoretical regret bound is established with proof to be over-performed than other MAB algorithms. A real application on maintenance recovery models refinement is explored.

Compared with traditional sports, the data of this industry is large in size and has the characteristics of easy-accessing and normalization. Based on these, data mining and machine learning methods can be applied to improve players' skills and help players make strategies. In this paper, a new approach predicting the outcome of an electronic sport DOTA2 was proposed. In earlier studies, the heroes' draft of a team was represented by unit vectors or its evolution, so the complex interactions among heroes were not captured. In our approach, the outcome prediction was performed in two steps. In the first step, Heroes in DOTA2 were quantified from 17 aspects in a more accurate way. In the second step, we proposed a new method to represent a heroes' draft. A priority table of 113 heroes was created based on the prior knowledge to support this method. The evaluation indexes of several machine learning methods on this task have been compared and analyzed in this paper. Experimental results demonstrate that our method was more effective and accurate than previous methods.","PeriodicalId":211585,"journal":{"name":"Proceedings of 2018 International Conference on Mathematics and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133281762","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 situation, it is minimizing misclassification costs rather than classification accuracy that is the primary goal of classification algorithms. To tackle this problem and improve the performance of classifiers, sampling is widely employed. In this paper, we propose a new diversity-based under-sampling technique for class-imbalanced datasets. The key idea is to balance a data set by choosing only the potential informative samples of the majority class according to diversity of class probability calculation. The experimental results on 5 class-imbalanced datasets show that our method performs better than two existing sampling techniques in terms of total misclassification costs.","PeriodicalId":211585,"journal":{"name":"Proceedings of 2018 International Conference on Mathematics and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114756515","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}

However, due to the consistency of multi-source information in emotional expression, emotion recognition based on single modal information is still unsatisfactory. Therefore, we proposed a feature fusion algorithm based on Discriminative Canonical correlation analysis, two modes are dealt with simultaneously, the correlation between the two classes of samples is taken as a similarity measure, introduced the class information of the sample, Fully consider the correlation between similar samples and the correlation between different samples. We use the DEAP database and use the DCCA method to fuse the physiological signals and the EEG signals, which greatly improves the classification effect. The classification of liking dimension is 68.21%, which is about 10% higher than other methods and about 2% higher than the CCA model.","PeriodicalId":211585,"journal":{"name":"Proceedings of 2018 International Conference on Mathematics and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125873426","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}
