On Leveraging Variational Graph Embeddings for Open World Compositional Zero-Shot Learning

no code implementations23 Apr 2022 Muhammad Umer Anwaar, Zhihui Pan, Martin Kleinsteuber

The task in Compositional Zero-Shot learning (CZSL) is to learn composition of primitive concepts, i. e. objects and states, in such a way that even their novel compositions can be zero-shot classified.

Metapath- and Entity-aware Graph Neural Network for Recommendation

1 code implementation22 Oct 2020 Muhammad Umer Anwaar, Zhiwei Han, Shyam Arumugaswamy, Rayyan Ahmad Khan, Thomas Weber, Tianming Qiu, Hao Shen, Yuanting Liu, Martin Kleinsteuber

In this paper, we employ collaborative subgraphs (CSGs) and metapaths to form metapath-aware subgraphs, which explicitly capture sequential semantics in graph structures.

Mend The Learning Approach, Not the Data: Insights for Ranking E-Commerce Products

1 code implementation24 Jul 2019 Muhammad Umer Anwaar, Dmytro Rybalko, Martin Kleinsteuber

In the literature, it is proposed to employ user feedback (such as clicks, add-to-basket (AtB) clicks and orders) to generate relevance judgments.
