The work addresses an important gap in the recent computer vision based artificial intelligence techniques to build smart parking systems. Our results show that our approach decreases the human effort needed by upto a compelling 86%. We show that the percentage of the available parking spots that are automatically detected through our approach accumulates over time and, in theory, can approach a 100%, on a day when all the parking spots are fully occupied. In other words, the approach is designed to have its highest performance over a busy parking lot during the busiest time.","PeriodicalId":202857,"journal":{"name":"Proceedings of the 2020 3rd International Conference on Machine Learning and Machine Intelligence","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128254377","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 knowledge is used for estimating a braking command to improve the learning efficiency, and DDQN determines the execution time of the command to avoid frequent switching of commands and ultimately reach better stopping decisions.

On the one hand, the 2D CNNs have difficulty in modeling the long-term temporal dependencies though they are computationally cheap. On the other hand, 3D CNNs have the ability to perceive temporal cues however lead to a high computational cost. In this paper, we propose a generic building block named Split and Attentive-aggregated Learnable Shift Module (SALSM) which has capacity of modeling spatiotemporal representations while maintain the complexity of the 2D CNN. Specifically, we split the input tensor into multiple groups, and conduct adaptive shift operations by applying the learnable shift kernels for different channels of each group along time dimension, so that the spatiotemporal information from neighboring frames can be mingled with 2D convolutions. The output feature maps of each group are integrated together with attention mechanism. With SALSM plugged in, the 2D CNN is enhanced to handle temporal information and become a highly efficient spatiotemporal feature extractor with little parameters and computational cost. We conduct ablation experiments to verify the effectiveness of our method, and our proposed SALSM achieves competitive or even better results over the state-of-the-art methods on several benchmark datasets.","PeriodicalId":202857,"journal":{"name":"Proceedings of the 2020 3rd International Conference on Machine Learning and Machine Intelligence","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130561954","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 experiment results suggest that the CC-CMA-ES is a fast and accurate approach for large-scale DED problems in terms of computation time, solution quality and convergence speed. Integrating CMA-ES into CC the framework can reduce the computation time by 97.5%, compared with basic CMA-ES, revealing the great potential of CC-CMA-ES for solving more difficult large-scale DED problems.","PeriodicalId":202857,"journal":{"name":"Proceedings of the 2020 3rd International Conference on Machine Learning and Machine Intelligence","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129798871","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}

Recently, powered Chinese Restaurant Process (pCRP) is purposed to eliminate the counterfactual small clusters. However, it violates the usual and indispensable exchangeability assumption of DPM. In this paper, we propose a new method called proportional Chinese Restaurant Process (pro-CRP) that keeps the property of exchangeability while reduces the number of unnecessary small clusters.
