Provably Efficient Representation Learning with Tractable Planning in Low-Rank POMDP

2023 · arXiv (Cornell University)

In this paper, we study representation learning in partially observable Markov Decision Processes (POMDPs), where the agent learns a decoder function that maps a series of high-dimensional raw observations to a compact representation and uses …

Exploring Hierachical Neighbor Information Interaction for Few-Shot Knowledge Graph Completion

2024

Few-shot knowledge graph completion (FKGC) aims to use a few-shot reference entity pairs to infer unknown facts and complete triple information. Typically, existing methods solely learn entity embeddings from their respective neighborhoods, resulting in inadequately …
