In conversation using binaural hearing aids, continuous tracking of sound sources with acoustics signals are sometimes complicated because sound sources move dynamically. In order to make the tracking of sound sources simple, it is considered to be helpful to use non-verbal information in communication. Since user's body movement, including a head, corresponds to speakers' positions, it is possible to estimate communication zone where sound sources locate by the head direction. In this paper, a head movement in conversation, as non-verbal information in communication, is focused, and two zone detection methods are discussed. A rotational angle of head movement is estimated by both acceleration by an accelerometer and angular velocity by angular velocity sensor which is attached to left ear position. The classification of spatial communication zone is performed by two methods, the threshold method and the support vector machine (SVM). As the results, performance on estimation of the target direction by the threshold-based method was slightly better than that by the SVM-based method.","PeriodicalId":154359,"journal":{"name":"2013 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131319928","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}

Many studies about CRE have used a common bias value among all user equipments (UEs), while the optimal bias values that minimize the number of UE outages vary from one UE to another. The optimal bias value that minimizes the number of UE outages depends on several factors such as the dividing ratio of radio resources between macro base stations (MBSs) and PBSs, it is given only by the trial and error method. In this paper, we propose a scheme to select a cell by using Q-learning algorithm where each UE learns which cell to select to minimize the number of UE outages from its past experience independently. Simulation results show that, compared to the practical common bias value setting, the proposed scheme reduces the number of UE outages and improves network throughput in the most cases. Moreover, instead of the degradation of the performances, it also solves the storage problem of our previous work.","PeriodicalId":154359,"journal":{"name":"2013 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131252943","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}

Existing cooperative relaying schemes primarily focus on single-source cooperative networks and aim to maximize diversity gain exploitation, yet ignore the extra energy consumption used by relay nodes and fairness between source nodes. Instead, our object is to minimize relay power consumption and maintain network-wide fairness without throughput penalty. The considered problem includes two parts, namely source scheduling and relay assignment that are addressed separately. We derive the feasible condition for the green source-relay assignment problem and show that it is NP-hard. We propose a heuristic algorithm that deliver good performance with low complexity. Simulation results are presented to evaluate the efficacy of the proposed scheme in terms of average throughput, throughput fairness, average relay power consumption, and average outage probability, as compared to two related schemes, under both independent and identically distributed (i.i.d.) and independent and non-identically distributed (i.n.d.) channel configurations.","PeriodicalId":154359,"journal":{"name":"2013 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130507720","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}

To achieve this goal, the input utterance is decoded as the affective state by an emotion recognizer and a word sequence by an imperfect speech recognizer separately. Besides, four types of evidences are employed to grade the score of each recognized word. The recognized word sequence is used to derive the candidate sentences to alleviate the problem of unexpected language usage for the cognitive state predicted by the vector space-based dialogue act detection. The Boltzmann selection based method is then employed to predict the next possible act in the spoken dialogue system according to the affective-cognitive states. A model of affective anticipatory reward that is assumed to arise from the emotional seeking system is adopted for enhancing the efficacy of dialogue act detection. Finally, the evaluation data are collected and the experimental results confirm the improved performance of the proposed approach compared to the baseline system on the task completion rate.","PeriodicalId":154359,"journal":{"name":"2013 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115869053","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 each DIBR-synthesized image, however, there remain disocclusion holes with missing pixels corresponding to spatial regions occluded from view in the reference images. To complete these holes, unlike previous schemes that rely heavily (and unrealistically) on the availability of a high-quality depth map in the virtual view for inpainting of the corresponding texture map, in this paper a new Joint Texture-Depth Inpainting (JTDI) algorithm is proposed that simultaneously fill in missing texture and depth pixels. Specifically, we first use available partial depth information to compute priority terms to identify the next target pixel patch in a disocclusion hole for inpainting. Then, after identifying the best-matched texture patch in the known pixel region via template matching for texture inpainting, the variance of the corresponding depth patch is copied to the target depth patch for depth inpainting. Experimental results show that JTDI outperforms two previous inpainting schemes that either does not use available depth information during inpainting, or depends on the availability of a good depth map at the virtual view for good inpainting performance.","PeriodicalId":154359,"journal":{"name":"2013 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133995464","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}
