Complex-valued Neurons Can Learn More but Slower than Real-valued Neurons via Gradient Descent

Neural Information Processing Systems

Complex-valued neural networks (CVNNs) utilize neuron models and operations in the complex-valued domain and are good at handling many complicated scenarios.






Open Visual Knowledge Extraction via Relation-Oriented Multimodality Model Prompting

Neural Information Processing Systems

Existing methods on visual knowledge extraction often rely on the predefined format (e.g., sub-verb-obj tuples) or vocabulary (e.g., relation types), restricting the expressiveness of the extracted knowledge. In this work, we take a first exploration to a new paradigm of open visual knowledge extraction.


Sample based Explanations via Generalized Representers

Neural Information Processing Systems

We propose a general class of sample based explanations of machine learning models, which we term generalized representers . To measure the effect of a training sample on a model's test prediction, generalized representers use two components: a global sample importance that quantifies the importance of the training point to the model and is invariant to test samples, and a local sample importance that measures similarity between the training sample and the test point with a kernel.
