Public Policy and Decision Science

''This page is about the intersection of policy-making and machine learning. For an overview of policy-making and decision science, please see the Wikipedia page on this topic.''

When creating policies, decision-makers must often negotiate fundamental uncertainties in the underlying data and construct mathematical models to help them assess or trade off between different policy alternatives (ex-ante policy analysis). ML can help alleviate some of this uncertainty by extracting information from satellite imagery, sensors, social media posts, policy documents, and other source and provide new techniques for working with models commonly used by decision-makers (e.g. integrated assessment models, multi-objective optimization, etc.). When deciding between different policy options, it is necessary to understand how effectively each strategy will reduce emissions, as well as how society may be affected. ML can also help retroactively, by analyzing the text of existing policies and by performing causal inference on historical data (ex-post policy analysis).

Gathering decision-relevant data

 * Data management, cleaning and imputation
 * Remote sensing
 * Computational text analysis:

Decision science

 * Decision science
 * Multi-criteria decision-making

Modeling and planning

 * Agent-based modeling: ABMs are used in simulating the actions and interactions of agents in their environment, and ML can help integrate data-driven insights into these models, for example by learning rules or models for agents based on observational data.
 * Energy system modeling
 * Urban planning: With new techniques such as surrogate modeling, ML can help with complex planning tasks.
 * Power System Planning: Algorithms for planning new low-carbon energy infrastructure are often large and slow. ML can help speed up or provide proxies for these algorithms.
 * Integrated assessment models: IAMs are large simulations used to explore future societal pathways that are consistent with climate goals, which can be improved with ML.

Ex-post policy analysis

 * Causal inference with machine learning
