Subject: ADIA Competition For Papers in Causal Research

The majority of journal articles in the investment literature make
associational claims, instead of proposing falsifiable causal
theories. As a result, the investment literature can be described as a
collection of anecdotal empirical evidence, undermined by p-hacking,
backtest overfitting, and reproducibility problems. To become a
science, investing must first embrace causal reasoning.

To help correct this, ADIA Lab has launched its Award for Causal
Research in Investments. ADIA Lab will award USD 100,000 to the
authors of three papers that help advance the use of causal inference
in investing.

Subject: PhD Position, Physics-informed ML, Germany

Within the project "Automated Simulation Abstraction Pipeline" in
cooperation with Schaeffler Technologies AG & Co. KG we offer a
Doctorate position (75 %, TV-L 13, for 3 years) at the Department of
Mathematics at the Friedrich-Alexander-Universitat Erlangen-Nurnberg,
chair for Applied Mathematics (Prof. Martin Burger), starting as soon
as possible.

The focus of the proposed PhD project is the development of physics-
informed machine learning approaches for the abstraction of simulation
tools for roller bearings. State-of-the-Art techniques from machine
learning, including deep neural networks, shall be made available to
learn the relation between various and input- and output-parameters
relevant for roller bearings, based on synthetic data from available
simulation tools. A key issue in method development is to develop
adaptive sampling strategies for the training data.

The project deals with the combination of machine learning techniques
and numerical schemes for partial differential equations. Therefore,
an above-average master's degree in mathematics, data science, or a
related discipline is required. We further expect sound knowledge in
numerical methods and machine learning, including experience with
programming and implementation of algorithms. A background in
continuum mechanics and finite element methods is useful.

your grades, and contact details of a reference, if possible)
