Automated Inference and the Future of Econometrics: A comment
This note discusses the (dis-)similarities between automated inference and computer-aided decisions, at the interface of econometrics and economics. It is argued that computer-aided decisions are best suited for scienti?c communication. For the future, the topic of learning is singled out as one of the most promising area of integration of econometric techniques and economics.
Assigned responsibility for remote robot operation
The remote control of robots, known as teleoperation, is a non-trivial task, requiring the operator to make decisions based on the information relayed by the robot about its own status as well as its surroundings. This places the operator under significant cognitive load. A solution to this involves sharing this load between the human operator and automated operators. This paper builds on the idea of adjustable autonomy, proposing Assigned Responsibility, a way of clearly delimiting control responsibility over one or more robots between human and automated operators. An architecture for implementing Assigned Responsibility is presented
Liable, but Not in Control? Ensuring Meaningful Human Agency in Automated Decision-Making Systems
Automated decision making is becoming the norm across large parts of society, which raises
interesting liability challenges when human control over technical systems becomes increasingly
limited. This article defines "quasi-automation" as inclusion of humans as a basic rubber-stamping
mechanism in an otherwise completely automated decision-making system. Three cases of quasi-
automation are examined, where human agency in decision making is currently debatable: self-
driving cars, border searches based on passenger name records, and content moderation on social
media. While there are specific regulatory mechanisms for purely automated decision making, these
regulatory mechanisms do not apply if human beings are (rubber-stamping) automated decisions.
More broadly, most regulatory mechanisms follow a pattern of binary liability in attempting to
regulate human or machine agency, rather than looking to regulate both. This results in regulatory
gray areas where the regulatory mechanisms do not apply, harming human rights by preventing
meaningful liability for socio-technical decision making. The article concludes by proposing criteria
to ensure meaningful agency when humans are included in automated decision-making systems,
and relates this to the ongoing debate on enabling human rights in Internet infrastructure
An ontology-based approach to relax traffic regulation for autonomous vehicle assistance
Traffic regulation must be respected by all vehicles, either human- or
computer- driven. However, extreme traffic situations might exhibit practical
cases in which a vehicle should safely and reasonably relax traffic regulation,
e.g., in order not to be indefinitely blocked and to keep circulating. In this
paper, we propose a high-level representation of an automated vehicle, other
vehicles and their environment, which can assist drivers in taking such
"illegal" but practical relaxation decisions. This high-level representation
(an ontology) includes topological knowledge and inference rules, in order to
compute the next high-level motion an automated vehicle should take, as
assistance to a driver. Results on practical cases are presented
Learning a Partitioning Advisor with Deep Reinforcement Learning
Commercial data analytics products such as Microsoft Azure SQL Data Warehouse
or Amazon Redshift provide ready-to-use scale-out database solutions for
OLAP-style workloads in the cloud. While the provisioning of a database cluster
is usually fully automated by cloud providers, customers typically still have
to make important design decisions which were traditionally made by the
database administrator such as selecting the partitioning schemes.
In this paper we introduce a learned partitioning advisor for analytical
OLAP-style workloads based on Deep Reinforcement Learning (DRL). The main idea
is that a DRL agent learns its decisions based on experience by monitoring the
rewards for different workloads and partitioning schemes. We evaluate our
learned partitioning advisor in an experimental evaluation with different
databases schemata and workloads of varying complexity. In the evaluation, we
show that our advisor is not only able to find partitionings that outperform
existing approaches for automated partitioning design but that it also can
easily adjust to different deployments. This is especially important in cloud
setups where customers can easily migrate their cluster to a new set of
(virtual) machines
MRI-based Surgical Planning for Lumbar Spinal Stenosis
The most common reason for spinal surgery in elderly patients is lumbar
spinal stenosis(LSS). For LSS, treatment decisions based on clinical and
radiological information as well as personal experience of the surgeon shows
large variance. Thus a standardized support system is of high value for a more
objective and reproducible decision. In this work, we develop an automated
algorithm to localize the stenosis causing the symptoms of the patient in
magnetic resonance imaging (MRI). With 22 MRI features of each of five spinal
levels of 321 patients, we show it is possible to predict the location of
lesion triggering the symptoms. To support this hypothesis, we conduct an
automated analysis of labeled and unlabeled MRI scans extracted from 788
patients. We confirm quantitatively the importance of radiological information
and provide an algorithmic pipeline for working with raw MRI scans
