| 1 | Multimodal Sentiment Analysis Using BiGRU and Attention-Based Hybrid Fusion Strategy显示文摘Recently,multimodal sentiment analysis has increasingly attracted attention with the popularity of complementary data streams,which has great potential to surpass unimodal sentiment analysis.One challenge of multimodal sentiment analysis is how to design an efficient multimodal feature fusion strategy.Unfortunately,existing work always considers feature-level fusion or decision-level fusion,and few research works focus on hybrid fusion strategies that contain feature-level fusion and decision-level fusion.To improve the performance of multimodal sentiment analysis,we present a novel multimodal sentiment analysis model using BiGRU and attention-based hybrid fusion strategy(BAHFS).Firstly,we apply BiGRU to learn the unimodal features of text,audio and video.Then we fuse the unimodal features into bimodal features using the bimodal attention fusion module.Next,BAHFS feeds the unimodal features and bimodal features into the trimodal attention fusion module and the trimodal concatenation fusion module simultaneously to get two sets of trimodal features.Finally,BAHFS makes a classification with the two sets of trimodal features respectively and gets the final analysis results with decision-level fusion.Based on the CMU-MOSI and CMU-MOSEI datasets,extensive experiments have been carried out to verify BAHFS’s superiority. | Zhizhong Liu Bin Zhou Lingqiang Meng Guangyu Huang | 2023 | Intelligent Automation & Soft Computing2023，37，8： | 1 |
| 2 | Novel thioxanthone host material with thermally activated delayed fluorescence for reduced efficiency roll-off of phosphorescent OLEDs显示文摘2,7-Di(9,9-dimethyl-9 H-fluoren-1-yl)-9 H-thioxanthen-9-one(DMBFTX) with thermally activated delayed fluorescence(TADF) was well designed and synthesized. The phosphorescent organic lightemitting device(PHOLED) based on this novel TADF host material displays a stable red phosphorescence region, a peak external quantum efficiency(EQE) value of 12.9% and a low EQE roll-off of 38.8% at a luminance of 10000 cd/m^2, which is benefited from the reverse intersystem crossing(RISC) of TADF host and less populated triplet exitons. Notably, the red device based on the TADF host DMBFTX exhibits superior electroluminescence performance and reduced efficiency roll-off compared with the one hosted by commercially available host 1,3-bis(9-carbazolyl)benzene(mCP), illustrating the high potential of employing the TADF host material with small energy gap to reduce efficiency roll-off in PHOLED. | Hui Wang Xiaopeng Lv Lingqiang Meng Xiaofang Wei Ying Wang Pengfei Wang | 2018 | Chinese Chemical Letters2018，29，3： | 1 |
