Our task is to build a model to make multi-label predictions for unknown examples that contain multiple views. 3.2 Extraction of Shared and Private Features The current MVML algorithms usually map the feature vectors from different views into a shared subspace when acquiring the features shared to...

Paper tables with annotated results for Interpretable Multi-task Learning with Shared Variable Embeddings
The framework consists of a cross-modal prediction task and a sentiment regression model. Two cross-modal prediction models, namely text-to-visual and text-to-acoustic models, are trained to explore shared and private semantics from non-text modalities. Considering that shared semantics contain more...
(CNNs) commonly used in visual neuroscience61,91. CNNs typically reduce dimensionality across layers92,93, putting pressure on the model to gradually discard task-irrelevant, low-level information and retain only high-level semantic content. In contrast, popular Transformer architectures maintain the ...
