Research

Kweku Opoku-Agyemang has new research on combining randomized controlled trials with reinforcement learning from human feedback. Read the paper here.

This paper introduces an approach where a technique commonly used in modern video games and large language models, generates the candidate interventions and RCTs (randomized controlled trials) test them experimentally. The approach executes traditional RCTs, cluster trials and adaptive experiments.

Kweku Opoku-Agyemang has new research on causal inference. Read the paper here.

This paper introduces a treatment dummy variable concept for data contexts where the treatment status of an individual is not fully observed or determined by the researcher, but depends on how much the instrument affects the probability of receiving the treatment.

Kweku Opoku-Agyemang has new research on app platform economies. Read the paper here.

Economies of scope are a key economic result from the late 1970s. To introduce a novel generalization of economies of scope for the app market and virtual reality era, that also works for platforms of all kinds, the paper develops a new model of average cost reductions based on enabling products to have multiple features or functions.

Machine Learning X Doing Research Highlights.

MLXD WORKING PAPER 1

Livestream: Contextual Bandits Meet Regression Discontinuity Designs.

Kweku Opoku-Agyemang.

Technology firms of all kinds face an unwieldy overflow of data in the twenty-first century: a constant waterfall of information. Innovative research methods can help unlock their full potential. In this working paper, Kweku Opoku-Agyemang presents statistical causal inference techniques for such datastreams.

“From social media to streaming platforms and smartphones, the exciting thing about the data revolution is that it provides the opportunity for decision makers to be better-informed than ever before.” Kweku observes. The updated version of the paper is here.

PROPOSAL INVITED, NATURE MACHINE INTELLIGENCE | MLXD WORKING PAPER 2

The Economics of Human-Centered Artificial Intelligence.

Kweku Opoku-Agyemang.

The rise of machine learning and the need for algorithmic fairness offers new opportunities for engagement with economics. Kweku Opoku-Agyemang discusses his perspective in a working paper.

“The lines between AI and the economy are increasingly blurred”, Opoku-Agyemang notes.

Econometric Causal Inference for Computer Vision: Image Natural Experiments Inspired by the Social Sciences.

Kweku Opoku-Agyemang.

From facial recognition to self-driving cars, image data is an increasingly important part of our lives and we must better understand how it can be a force for good. Kweku Opoku-Agyemang presented at the CVPR 2021 Beyond Fairness Workshop on how computer vision can benefit from causal inference methods traditionally used in the economic and social sciences.

“The goal is for statistical context of image data required for better decisions.” Kweku notes. The paper is here.

MLXD WORKING PAPER 3

The Education Economics of the Future of Work.

Kweku Opoku-Agyemang.

The future of work is one of the most profound economic events of our times, with AI poised to impact productivity and innovation in every corner of society. In this working paper, Kweku Opoku-Agyemang sheds light on this critical issue.

“It’s encouraging to see the recent progress in AI, but the best is yet to come.” says Kweku. The paper is here.
