Causally Learning an Optimal Rework Policy

no code implementations7 Jun 2023 Oliver Schacht, Sven Klaassen, Philipp Schwarz, Martin Spindler, Daniel Grünbaum, Sebastian Imhof

In this paper, we apply double/debiased machine learning (DML) to estimate the conditional treatment effect of a rework step during the color conversion process in opto-electronic semiconductor manufacturing on the final product yield.

DoubleML -- An Object-Oriented Implementation of Double Machine Learning in Python

3 code implementations7 Apr 2021 Philipp Bach, Victor Chernozhukov, Malte S. Kurz, Martin Spindler

Uniform Inference in High-Dimensional Generalized Additive Models

no code implementations3 Apr 2020 Philipp Bach, Sven Klaassen, Jannis Kueck, Martin Spindler

We develop a method for uniform valid confidence bands of a nonparametric component $f_1$ in the general additive model $Y=f_1(X_1)+\ldots + f_p(X_p) + \varepsilon$ in a high-dimensional setting.
