General non-linear imitation leads to limit cycles in eco-evolutionary dynamics
We extrapolate from the linear imitation function to general imitation function, which can be non-linear.
MDAN: Multi-level Dependent Attention Network for Visual Emotion Analysis
Existing deep approaches try to bridge the gap by directly learning discrimination among emotions globally in one shot without considering the hierarchical relationship among emotions at different affective levels and the affective level of emotions to be classified.
Prediction of Depression Severity Based on the Prosodic and Semantic Features with Bidirectional LSTM and Time Distributed CNN
For the text modality, we use global vectors for word representation (GloVe) to perform word embeddings and the embeddings are fed into the Bi-LSTM network.
