Overview

Welcome! My name is Philipp Geiger, on this web page I give an overview over my work in research and software development, and general background.

I'm an industry research scientist at Bosch Center for Artificial Intelligence. Before, I did my doctorate in computer science and a postdoc at Max Planck Institute for Intelligent Systems and University of Stuttgart, including a stay at Microsoft Research Cambridge, and my diplom in mathematics with philosophy as side subject at Heidelberg University and Humboldt University of Berlin.

Generally, I conduct research and development in a broad range of topics in machine learning (core part of artificial intelligence) and multiagent systems (analysis and optimization of multiple intelligent decision makers' interaction behavior). Often, this combines project-driven software engineering and experimental aspects with statistical/mathematical analysis, and aims at innovative solutions for problems important to business and society as a whole. Recently, I've been focusing on deep generative multiagent imitation learning, deep model-based reinforcement learning and game theory, and I'm also exploring foundation models, in particular fine-tuning of vision language models. Applications I work on include energy-efficient building control and autonomous driving and its safety validation (see also further background).

I'm also increasingly interested in the political aspects of artificial intelligence.

Selected publications (see also all publications and further material):

1. Fail-Safe Adversarial Generative Imitation Learning. (2022). TMLR.
2. Learning game-theoretic models of multiagent trajectories using implicit layers. (2021). AAAI.
3. Causal inference by identification of vector autoregressive processes with hidden components. (2015). ICML. [Slides.]

News

• AI-based modeling for energy-efficient buildings:

  Energy-efficient buildings are a high-dimensional, complex modeling and optimization problem. We launched a Kaggle modeling competition on this problem: with a big dataset consisting of 1.5 years and hundreds of sensor time series, of a Bosch campus with multiple buildings. This is part of the EU-funded ELIAS project.

• Analyzing Closed-loop Training Techniques for Realistic Traffic Agent Models in Autonomous Highway Driving Simulations:

  At Bosch Research, we conducted an extensive comparison of different approaches for (generative) imitation learning of realistic traffic agents from real-world human driving data, for driving behavior simulations, check out our preprint.

• On Learning the Tail Quantiles of Driving Behavior Distributions via Quantile Regression and Flows:

  In our recent ITSC workshop paper, we investigate two approaches for estimating the (tail) quantiles of driver action distributions (policies), including a version of conditional normalizing flows.
