Uncertainty Propagation through Trained Deep Neural Networks Using Factor Graphs

no code implementations10 Dec 2023 Angel Daruna, Yunye Gong, Abhinav Rajvanshi, Han-Pang Chiu, Yi Yao

Our implementation balances the benefits of sampling and analytical propagation techniques, which we believe, is a key factor in achieving performance improvements.

Explainable Knowledge Graph Embedding: Inference Reconciliation for Knowledge Inferences Supporting Robot Actions

1 code implementation4 May 2022 Angel Daruna, Devleena Das, Sonia Chernova

Results from our algorithmic evaluation affirm our model design choices, and the results of our user studies with non-experts support the need for the proposed inference reconciliation framework.

Towards Robust One-shot Task Execution using Knowledge Graph Embeddings

no code implementations10 May 2021 Angel Daruna, Lakshmi Nair, Weiyu Liu, Sonia Chernova

We validated the approach on a physical platform, which resulted in the successful generalization of initial task plans to 38 of 50 execution environments with errors resulting from autonomous robot operation included.

RoboCSE: Robot Common Sense Embedding

no code implementations24 Mar 2019 Angel Daruna, Weiyu Liu, Zsolt Kira, Sonia Chernova

Autonomous service robots require computational frameworks that allow them to generalize knowledge to new situations in a manner that models uncertainty while scaling to real-world problem sizes.
