However, due to the influence of the detection equipment and environment, there usually exist noise data which might have effects on the superheat adjustment. CNSMO(Class Noise based Sequential Minimal Optimization) [1] has a good performance in processing the data containing noise and prediction of superheat, which contains a large number of noise samples such that the generalizability of conventional SVMs deteriorates. The main reason is that the kernel mapping of the noise samples is likely to lead to overfitting in conventional SVMs [2]-[4]. However, ineffectiveness of CNSMO appears in asymmetric data. To deal with the problem, we optimize the relative density threshold and propose the IRDNF-SMO (Improved Relative Density Noise Filter based SMO algorithm). In the IRDNF-SMO, not only the relative density model is used for class noise detection, but the threshold of the relative density is optimized instead of setting to the fixed value such that the ineffectiveness is alleviated in asymmetric data. The experimental results on industry data sets and benchmark data sets demonstrated that the proposed algorithm has higher prediction accuracy in the data sets.","PeriodicalId":144958,"journal":{"name":"2018 IEEE International Conference on Big Knowledge (ICBK)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127561405","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}

There is a common problem in the existing methods, that is, quantization error at weak edges, noise or soft shadows may cause inaccurate blur estimates at some edge locations. In the proposed methods, L0 smoothing technology is employed to screen the effective edge which is advantageous to estimate defocus information and denoising. The guided image filter is applied to propagate the blur amount at edge locations to the entire image, a refined defocus map can be obtained. Then the recovery of the relative depth order on the image is achieved from the blur map. At last, T-junction is adopted to eliminate the ambiguity in the depth map over the focal plane. Experimental results demonstrate that compared with the previous approaches, the algorithm can effectively produces high quality depth maps.","PeriodicalId":144958,"journal":{"name":"2018 IEEE International Conference on Big Knowledge (ICBK)","volume":"97 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120885198","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}

Surprisingly, while supply chain optimization has been in the spotlight for many years, its crucial inventory management component has often been neglected. Companies that have invested in supply chain optimization have typically allowed inventory management policies to be determined by outdated textbook models or even “managerial guesswork,” without consideration of employing advanced analytics technology. Recent discoveries have shown, however, that many organizations can save millions of dollars annually by applying state-of-the-art analytics to optimize inventories. Moreover, substantial gains in profits over and above those obtained from “good” analytics approaches result by using special models from a meta-analytics framework, which combines metaheuristics with analytics. We demonstrate this finding by an integrated meta-analytics platform that combines network optimization, netform modeling and simulation optimization for inventory management. We report computational tests that compare our meta-analytics approach to the status quo methodology customarily used for inventory management and to a recent innovation in inventory management reported to save over $90 million for a major U.S. retail firm. The results show that our meta-analytics approach provides dramatic improvements over both of these alternative approaches, yielding appreciably better levels of service and greater cost savings, and having broad implications for modern inventory management policies.

Nodes are the actors, persons, etc, and edges are the interactions among the nodes. These interactions change frequently over a time in the social networks, make temporally evolving communities. This change over a time and interactions in the communities cause evolution patterns. These evolution patterns are called as events of the Social Networks. In our paper, we detect the patterns of the interactions between the nodes and then detect the events. To achieve that goal we need to detect community. Community detection provides only structural change but it is not finding the network changes that happen over a time period. So, community mining is required to identify both the structural change and network change. In this paper, we introduce a new community mining approach to identify the similar communities and their events evolution. To do this task, we need to find current time frame t_i community changes with respect to community change in past time frame t_(i-1). To achieve this goal we are using DBLP citation dataset. This DBLP dataset represents the author and co-author relationship. In the DBLP citation dataset, we identified the existing communities and the way these communities evolve over a time period.","PeriodicalId":144958,"journal":{"name":"2018 IEEE International Conference on Big Knowledge (ICBK)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130291805","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}

Traditional statistics methods focus on testing the correlation of variables pairwise. However, the correlation has rather limited performance on real causal influence. In this paper, we focus on an interpretable and visible approach to detect causal relationship networks in order to study risk factors of older adult falls. Learning the skeleton of the network is challenging since it is hard to mine indirect relationships. Variables could have dependence given other variables. Furthermore, orienting appropriate direction is tough because real-world data may include hidden information. Researchers cannot control it like a simulated data set. Here we propose a method based on the Bayesian causal relationship, which we call the Time Logic PC algorithm (TL-PC). We use the TL-PC on the older adults fall application and show the explainable and reliable time logical causal relationships.","PeriodicalId":144958,"journal":{"name":"2018 IEEE International Conference on Big Knowledge (ICBK)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130643629","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}

A reinforcement learning approach to decision tree building seems more suitable as it aims at maximizing the long-term return rather than optimizing a short-term goal. In this paper, a reinforcement learning approach is used to train a Markov Decision Process (MDP), which enables the creation of a short and highly accurate decision tree. Moreover, the use of reinforcement learning naturally enables additional functionality such as learning under concept drifts, feature importance weighting, inclusion of new features and forgetting of obsolete ones as well as classification with incomplete data. To deal with concept drifts, a reset operation is proposed that allows for local re-learning of outdated parts of the tree. Preliminary experiments show that such an approach allows for better adaptation to concept drifts and changing feature spaces, while still producing a short and highly accurate decision tree.","PeriodicalId":144958,"journal":{"name":"2018 IEEE International Conference on Big Knowledge (ICBK)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130666080","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}

Yet there is no standardized framework which would allow for a straightforward and repeatable comparison of different investment strategies, leading to a lack of clarity on the state of the art and thereby limiting progress in understanding the field. In the present work we introduce a novel, open-source framework which aims at addressing the crucial limitation. In particular, as our first contribution we describe a highly flexible and readily extensible framework which through its modularity and 'agnosticism', is capable of dealing with diverse types of data and research questions. We summarize its design and functionalities, and as an additional contribution present a number of baseline experiments on examples of publicly available financial data sets. We hope that the two contributions will serve to provide a degree of standardization of experimental analyses in the field, increase our understanding of the state of the art, as well as drive future efforts in increasing the repeatability and transparency of research efforts. Lastly, we also described several examples of experiments which demonstrate the use of the framework, and will include the full corresponding source code in the release.","PeriodicalId":144958,"journal":{"name":"2018 IEEE International Conference on Big Knowledge (ICBK)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134465188","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}

Our proposed Sampling-A-Posterior (SAP) framework publishes a noisy posterior distribution which is guaranteed to be differentially private. This is different from traditional private approaches which publish a point estimate of the model. In the proposed SAP framework, we represent the likelihood function as a linear combination of basis functions and use the K-norm mechanism to publish the coordinate vector of the total likelihood function. The proposed framework can be applied to design differentially private mechanisms for parametric models and flexible parametric models in survival analysis. The experimental results have shown the effectiveness of the proposed framework on real survival datasets.","PeriodicalId":144958,"journal":{"name":"2018 IEEE International Conference on Big Knowledge (ICBK)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123924914","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, to the best of our knowledge, only a few ERE works have been done for Chinese corpus. Because the syntactic features of Chinese sentences and English sentences are very different, existing algorithms for English corpus cannot be directly applied to Chinese corpus. Thus, in this paper, we propose a novel Chinese entity extraction system based on syntactic features (named SF-CERE). The basic idea of SF-CERE is given as follows. Firstly, we extract candidate relation triples based on verbs and verb-nouns as relation keywords to avoid pre-defining relation types. Secondly, the triples are filtered using the positional constraints between relation keywords and entity pairs. Thirdly, we summarize four major Chinese syntactic features to expand the identified relation triples and improve accuracy. Finally, we use the method of relation transfer to mine and infer implicit relation triples. The experimental results on two real-world dataset (i.e., the encyclopedia dataset and the news dataset) show that SF-CERE effectively improves the quality of the relation triples and obtains good extraction performance.","PeriodicalId":144958,"journal":{"name":"2018 IEEE International Conference on Big Knowledge (ICBK)","volume":"225 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130615969","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}

Among all algorithms detecting overlapping communities, Speaker-listener Label Propagation Algorithm (SPLA) represents one of the state-of-the-art approaches due to its high accuracy. However, in the face of overlapping communities with instability and unbalanced partitions, the performance of SLPA drastically degrades. To fill such a gap, we propose a novel community detection algorithm based on density optimization. The proposed algorithm leverages Jaccard similarity coefficient to quantify the similarity between two nodes, and then propagate the label of a node to its neighboring node with the highest similarity. In this way, the initial community is obtained. Due to the existence of an oversized community in the initial community, we argue that a good community structure should have a higher density within the community than outside the community. Therefore, the initial community should be divided again. If the density of the new community is larger than that of the original community, the node's label information is updated; otherwise not. Finally, extensive experiments are carried out on both artificial networks and real networks. The results show that the proposed approach can achieve higher NMI index and overlapping modularity, hence outperforming existing methods.","PeriodicalId":144958,"journal":{"name":"2018 IEEE International Conference on Big Knowledge (ICBK)","volume":"167 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120882479","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}
