Audio Sentiment Analysis by Heterogeneous Signal Features Learned from Utterance-Based Parallel Neural Network Abstract Audio Sentiment Analysis is an increasingly popular research area which extends the conventional text-based sentiment analysis to depend on the effectiveness of acoustic features extracted from speech. Graph-based. The complete graph is simple because of the homogeneity, while the star graph is heterogeneous, but also simple, because it has only one root (hub). 关注微信公众号：人工智能前沿讲习，公众号对话框回复"sffai27"获取讲者ppt。异质图在真实世界无处不在，异质图的分析也是数据挖掘的热门方向。. We provide a statistical framework to deal with heteroge-neous network data, proposing heterogeneous versions of the classical stochastic. Graph theoretical approaches. Similar toan entity-relationdiagram in a relational database, we use an abstract graph (i. Recently heterogeneous information network (HIN) has gained wide attention in recommender systems due to its flexibility in modeling rich objects and complex relationships. Formally, it is defined as follows. Linmei Hu, Tianchi Yang, Chuan Shi, Houye Ji, Xiaoli Li. Association for Computing Machinery, 2014.
