Data-Efficient and Interpretable Tabular Anomaly Detection

no code implementations3 Mar 2022 Chun-Hao Chang, Jinsung Yoon, Sercan Arik, Madeleine Udell, Tomas Pfister

In addition, the proposed framework, DIAD, can incorporate a small amount of labeled data to further boost anomaly detection performances in semi-supervised settings.

Extracting Expert's Goals by What-if Interpretable Modeling

no code implementations28 Oct 2021 Chun-Hao Chang, George Alexandru Adam, Rich Caruana, Anna Goldenberg

Although reinforcement learning (RL) has tremendous success in many fields, applying RL to real-world settings such as healthcare is challenging when the reward is hard to specify and no exploration is allowed.

NODE-GAM: Neural Generalized Additive Model for Interpretable Deep Learning

2 code implementations ICLR 2022 Chun-Hao Chang, Rich Caruana, Anna Goldenberg

Deployment of machine learning models in real high-risk settings (e. g. healthcare) often depends not only on the model's accuracy but also on its fairness, robustness, and interpretability.

Towards Robust Classification Model by Counterfactual and Invariant Data Generation

1 code implementation CVPR 2021 Chun-Hao Chang, George Alexandru Adam, Anna Goldenberg

Despite the success of machine learning applications in science, industry, and society in general, many approaches are known to be non-robust, often relying on spurious correlations to make predictions.

Purifying Interaction Effects with the Functional ANOVA: An Efficient Algorithm for Recovering Identifiable Additive Models

1 code implementation12 Nov 2019 Benjamin Lengerich, Sarah Tan, Chun-Hao Chang, Giles Hooker, Rich Caruana

Models which estimate main effects of individual variables alongside interaction effects have an identifiability challenge: effects can be freely moved between main effects and interaction effects without changing the model prediction.

Dynamic Measurement Scheduling for Event Forecasting using Deep RL

1 code implementation24 Jan 2019 Chun-Hao Chang, Mingjie Mai, Anna Goldenberg

We answer this question by deep reinforcement learning (RL) that jointly minimizes the measurement cost and maximizes predictive gain, by scheduling strategically-timed measurements.

Dynamic Measurement Scheduling for Adverse Event Forecasting using Deep RL

no code implementations1 Dec 2018 Chun-Hao Chang, Mingjie Mai, Anna Goldenberg

We address the scheduling problem using deep reinforcement learning (RL) to achieve high predictive gain and low measurement cost, by scheduling fewer, but strategically timed tests.

Explaining Image Classifiers by Counterfactual Generation

1 code implementation ICLR 2019 Chun-Hao Chang, Elliot Creager, Anna Goldenberg, David Duvenaud

We can rephrase this question to ask: which parts of the image, if they were not seen by the classifier, would most change its decision?
