In this paper, we propose a temporal-frequential attention model for sound event detection (SED). Our network learns how to listen with two attention models: a temporal attention model and a frequential attention model. Proposed system learns when to listen using the temporal attention model while it learns where to listen on the frequency axis using the frequential attention model. With these two models, we attempt to make our system pay more attention to important frames or segments and important frequency components for sound event detection. Our proposed method is demonstrated on the task 2 of Detection and Classification of Acoustic Scenes and Events (DCASE) 2017 Challenge and achieves competitive performance.
Sound event detection with weakly labeled data is considered as a problem of multi-instance learning. And the choice of pooling function is the key to solving this problem. In this paper, we proposed a hierarchical pooling structure to improve the performance of weakly labeled sound event detection system. Proposed pooling structure has made remarkable improvements on three types of pooling function without adding any parameters. Moreover, our system has achieved competitive performance on Task 4 of Detection and Classification of Acoustic Scenes and Events (DCASE) 2017 Challenge using hierarchical pooling structure.
Purpose: Taking into account previous research on the role that the parenting styles to which individuals are exposed during childhood have in shaping prosocial behaviors, attitudes and personality and so on, this study aims to investigate the relationship between parenting styles of parents and creativity. Design/Methodology/Approach: The creativity and the parenting style questionnaires were completed by 239 undergraduate student participants. Pearson correlation coefficients were extracted and regression analysis was performed. Findings: The results indicate that undergraduate students with democratic parents tend to show stronger creative thinking and open the way to further study what parental characteristics may be responsible for the development of creativity in undergraduate students. Research Limitations/Implications: Participants retrospectively assessed their parents' style. Future research may recruit both the actual parents of participants to collect more accurate data on parenting practices or use observational methods. Social Implications: This work seems to suggest that to achieve a more creative society, the ability of parents to raise their children by adopting a democratic style should be taken into account and-if needed-enhanced. Originality/Value: To the best of authors' knowledge, this is the first study to investigate the relationship between parenting styles of parents and creativity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
