Deep learning based wideband (16kHz) acoustic echo cancellation (AEC) approaches have surpassed traditional methods. This work proposes a deep hierarchical fusion (DHF) network with intra-network and inter-network to further improve the AEC performance. Meanwhile, this extends existing systems enable fullband (48kHz) while simultaneously ensuring automatic speech recognition compatibility by incorporating an ASR loss. The proposed system has ranked 2nd place in ICASSP 2022's Challenge.

Purpose Turnover intention is a critical predictor of an employee’s turnover behaviour. A high level rate significantly affects the productivity and morale enterprise. Previous research has indicated that job satisfaction plays role in influencing employee's intention, but underlying factors related to remain under-explored, which impedes development effective strategies for reducing intention. In addition, little examined context COVID-19 pandemic, specifically Chinese construction...

Multinomial logit bandit is a sequential subset selection problem which arises in many applications. In each round, the player selects K-cardinality from N candidate items, and receives reward governed by multinomial (MNL) choice model considering both item utility substitution property among items. The player's objective to dynamically learn parameters of MNL maximize cumulative over finite horizon T. This faces exploration-exploitation dilemma, involved combinatorial nature makes it...

In Semantic Web, modeling knowledge graph based on RDF becomes more and popular. There is quite a lot of spatiotemporal information in recent works focus not only general data but also data. Existing efforts are mainly to add labels RDF, which expand triple into quad or quintuple. However, extra often cause additional overhead for the system lead inefficient organization management. order overcome this limitation, we propose an stRDFS model by labeling properties with features corresponding...
