Beyond sparsity: Tree regularization of deep models for interpretability

M Wu, M Hughes, S Parbhoo, M Zazzi, V Roth… - Proceedings of the …, 2018 - ojs.aaai.org
The lack of interpretability remains a key barrier to the adoption of deep models in many
applications. In this work, we explicitly regularize deep models so human users might step …

Addressing leakage in concept bottleneck models

M Havasi, S Parbhoo… - Advances in Neural …, 2022 - proceedings.neurips.cc
Abstract Concept bottleneck models (CBMs) enhance the interpretability of their predictions
by first predicting high-level concepts given features, and subsequently predicting outcomes …

[HTML][HTML] Determinants of HIV-1 reservoir size and long-term dynamics during suppressive ART

N Bachmann, C Von Siebenthal, V Vongrad… - Nature …, 2019 - nature.com
The HIV-1 reservoir is the major hurdle to a cure. We here evaluate viral and host
characteristics associated with reservoir size and long-term dynamics in 1,057 individuals …

[HTML][HTML] Real-time prediction of COVID-19 related mortality using electronic health records

P Schwab, A Mehrjou, S Parbhoo, LA Celi… - Nature …, 2021 - nature.com
Abstract Coronavirus disease 2019 (COVID-19) is a respiratory disease with rapid human-to-
human transmission caused by the severe acute respiratory syndrome coronavirus 2 (SARS …

[HTML][HTML] Combining kernel and model based learning for HIV therapy selection

S Parbhoo, J Bogojeska, M Zazzi, V Roth… - AMIA Summits on …, 2017 - ncbi.nlm.nih.gov
We present a mixture-of-experts approach for HIV therapy selection. The heterogeneity in
patient data makes it difficult for one particular model to succeed at providing suitable …

Interpretable off-policy evaluation in reinforcement learning by highlighting influential transitions

O Gottesman, J Futoma, Y Liu… - International …, 2020 - proceedings.mlr.press
Off-policy evaluation in reinforcement learning offers the chance of using observational data
to improve future outcomes in domains such as healthcare and education, but safe …

The unintended consequences of discount regularization: Improving regularization in certainty equivalence reinforcement learning

S Rathnam, S Parbhoo, W Pan… - International …, 2023 - proceedings.mlr.press
Discount regularization, using a shorter planning horizon when calculating the optimal
policy, is a popular choice to restrict planning to a less complex set of policies when …

Regional tree regularization for interpretability in deep neural networks

M Wu, S Parbhoo, M Hughes, R Kindle, L Celi… - Proceedings of the AAAI …, 2020 - aaai.org
The lack of interpretability remains a barrier to adopting deep neural networks across many
safety-critical domains. Tree regularization was recently proposed to encourage a deep …

Optimizing for interpretability in deep neural networks with tree regularization

M Wu, S Parbhoo, MC Hughes, V Roth… - Journal of Artificial …, 2021 - jair.org
Deep models have advanced prediction in many domains, but their lack of interpretability
remains a key barrier to the adoption in many real world applications. There exists a large …
