Context Matters: Graph-based Self-supervised Representation Learning for Medical Images [article]

Li Sun, Ke Yu, Kayhan Batmanghelich
2020 arXiv   pre-print
We introduce a novel approach with two levels of self-supervised representation learning objectives: one on the regional anatomical level and another on the patient-level.  ...  In addition, the graph representation has the advantage of handling any arbitrarily sized image in full resolution.  ...  Importantly, the unsupervised approach has the capability of learning robust representation since the features are not optimized towards solving a single supervised task.  ...

2022 arXiv   pre-print
Recently, there has been a lot of focus on building XAI models, especially to provide explanations for understanding and interpreting the predictions made by deep learning models.  ...  An explainable AI (XAI) model aims to provide transparency (in the form of justification, explanation, etc) for its predictions or actions made by it.  ...  We are trying to learn the mapping from videos to its corresponding discourse representation (i.e. discourse tree) using end-to-end learning models.  ...

Graph Representation Learning Beyond Node and Homophily

You Li, Bei Lin, Binli Luo, Ning Gui
2022 IEEE Transactions on Knowledge and Data Engineering  
Unsupervised graph representation learning aims to distill various graph information into a downstream task-agnostic dense vector embedding.  ...  However, existing graph representation learning approaches are designed mainly under the node homophily assumption: connected nodes tend to have similar labels and optimize performance on node-centric  ...  The most important thing is to discover the interesting and challenging problem of representing graphs from the perspective of local assortativity. This will guide our next steps.  ...

Darius Afchar, Romain Hennequin, Vincent Guigue
2022 arXiv   pre-print
In computer vision, concept learning was therein proposed to adjust explanations to the right abstraction level (e.g. detect clinical concepts from radiographs).  ...  These methods have yet to be used for MIR. In this paper, we adapt concept learning to the realm of music, with its particularities.  ...  Unsupervised Hierarchy Mining Using knowledge graphs and taxonomies is frequent leverage in MIR [25] .

Unsupervised Keyphrase Extraction via Interpretable Neural Networks [article]

Rishabh Joshi and Vidhisha Balachandran and Emily Saldanha and Maria Glenski and Svitlana Volkova and Yulia Tsvetkov
2022 arXiv   pre-print
Prior approaches for unsupervised keyphrase extraction resort to heuristic notions of phrase importance via embedding similarities or graph centrality, requiring extensive domain expertise to develop them  ...  We show that this novel approach not only alleviates the need for ad-hoc heuristics but also achieves state-of-the-art results in unsupervised keyphrase extraction across four diverse datasets in two domains  ...  by computing an average over all the phrase-level label distributions such that l e = mean(l i ): L e = − T t=1 y t log(l e ) and computes a joint explanation and classification loss for the model as:  ...
