Recurrent Neural Network for Text Classification with ...

Figure 2: Three architectures for modelling text with multi-task learning. Motivated by the success of multi-task learning [Caruana, 1997], we propose three multi-task models to leverage super-vised data from many related tasks. Deep neural model is well suited for multi-task learning since the features learned from a task may be useful for ...

Therefore, different scales are also needed at different time steps as the notes have different durations at different times [Hu et al., 2019]. Recently, some methods have been proposed to select ap-propriate scales corresponding to each sample ...

Skeleton-Based Action Recognition With Shift Graph ...

spatial graph convolution and temporal graph convolution. For spatial graph convolution, the neighbor set of joints is defined as an adjacent matrix A ∈ {0,1}N×N. To spec-ify the spatial location of graph convolution, the adjacent matrix is typically partitioned into 3 partitions: 1) the cen-tripetal group, which contains neighboring nodes ...
