Discovering Latent Concepts Learned in BERT

no code implementations ICLR 2022 Fahim Dalvi, Abdul Rafae Khan, Firoj Alam, Nadir Durrani, Jia Xu, Hassan Sajjad

We address this limitation by discovering and analyzing latent concepts learned in neural network models in an unsupervised fashion and provide interpretations from the model's perspective.

Interpreting Criminal Charge Prediction and Its Algorithmic Bias via Quantum-Inspired Complex Valued Networks

no code implementations25 Jun 2021 Abdul Rafae Khan, Jia Xu, Peter Varsanyi, Rachit Pabreja

Our analysis of the importance of each input feature shows the critical causal impact on decision-making, suggesting that criminal histories are statistically significant factors, while identifiers, such as race and age, are not.

Grouping Words with Semantic Diversity

1 code implementation NAACL 2021 Karine Chubarian, Abdul Rafae Khan, Anastasios Sidiropoulos, Jia Xu

Deep Learning-based NLP systems can be sensitive to unseen tokens and hard to learn with high-dimensional inputs, which critically hinder learning generalization.
