An Interdisciplinary Approach
HAI’s research efforts gained significant momentum in the 2021-22 academic year. The team was excited to return to in-person events and to establish the Ethics and Society Review process as part of HAI’s grant programs.
HAI Research Focus
HAI focuses its research initiatives around three main priorities, each with its own vision and mission:
To develop technology that is equitable, researchers must understand how AI interacts with humans, as well as how it interacts with vital social structures and institutions.
Civics Education for a Just and Sustainable Future
Understanding and changing textbook content is one important lever in the multifaceted process required to redesign history and civics education. Patricia Bromley in the Graduate School of Education has designed a study that uses Natural Language Processing (NLP) to assess textbook content and document depictions of diversity, equity, and sustainability.
Augmenting Human Capabilities
HAI believes that breakthroughs in human-centered design methods will further progress in healthcare, education, sustainability, automation, and countless other domains.
Rating Systems and the Future of Algorithmic Worker Evaluation
A team from the Schools of Engineering and Humanities and Sciences is developing a forward-looking digital resumé for workers in online labor platforms. The project brings together statistical methodology, algorithm design, human-computer interaction, and political economy to enable the same career pathways for online workers that society takes for granted in offline work.
To create a machine-assisted—yet human-centered—world, the AI community must develop the next generation of techniques that overcomes the limitations of current algorithms, expands the class of problems that can be addressed, and complements human cognitive and analytic styles.
Toward Machine Models of Structured Human Reasoning through Explanation-based Meta-learning
Some of the most impressive achievements of the human mind have led to deep scientific understanding and powerful technologies. Two researchers from the Schools of Engineering and Humanities and Sciences seek to combine human and machine learning research to build artificially intelligent systems that could potentially achieve these abilities.
Grant Programs for AI Research
Since its founding, HAI’s grant programs have supported 248 faculty members from all seven Stanford schools. Many of these projects span multiple departments, in keeping with the commitment to support interdisciplinary AI research.
How HAI Research Grants Connect Departments
HAI Seed Grants
HAI seed research grants are designed to bring faculty together across disciplines to share knowledge and pursue new ideas. Three projects received notable awards to continue their research:
Hoffman-Yee research grants are made possible by a gift from philanthropists Reid Hoffman and Michelle Yee. In August 2022, HAI announced its second cohort of Hoffman-Yee Grant recipients. Six research teams were each awarded a total of $2.75 million to solve some of the most challenging problems in the field of AI. Each of the proposals went through a rigorous review with faculty, as well as an Ethics and Society review.
- Tuning Our Algorithmic Amplifiers: Encoding Societal Values into Social Media Algorithms
- MARPLE: Explaining What Happened through Multi-modal Simulation
- Foundation Models: Integrating Technical Advances, Social Responsibility, and Applications
- EAE Scores: A Framework for Explainable, Actionable and Equitable Risk Scores for Healthcare Decisions
- Matching Newcomers to Places: Leveraging Human-Centered AI to Improve Immigrant Integration
- Dendritic Computation for Knowledge Systems
Cloud Credit Grants
HAI saw record demand for cloud credit grants during AY 2021-22. This program provides advanced computational resources that researchers need to conduct rigorous AI projects. HAI allocates these credits to studies showing promising, novel, or emerging ideas.
In the second year of the Google Cloud Credit Grants, HAI awarded a total of $2.5 million in GCP credits to 48 faculty across 59 projects. The institute also launched the Microsoft Azure Cloud Credit Grants and awarded $330,000 in Azure credits to 7 faculty across 11 projects.

Center for Research on Foundation Models
Center for Research on Foundation Models (CRFM) celebrated its one-year anniversary in August 2022 and now counts more than 300 students, faculty, and postdocs working on relevant research projects.
This center was founded to drive fundamental advances in the responsible study, development, and deployment of foundation models. Foundation models are resource-intensive AI systems, such as GPT-3, Codex, StableDiffusion, Imagen, and AlphaFold, which are trained on broad data at scale. Foundation models
provide valuable representations for many downstream applications; however, the technology is advancing at a rapid pace and there are unknown risks that must be considered.
Stanford established CRFM to focus on three pillars:
The center conducts interdisciplinary research that lays groundwork for how foundation models should be built to make them more efficient, robust, interpretable, multimodal, and just. During the past academic year, CRFM scholars authored dozens of papers, including:
- The Time Is Now to Develop Community Norms for the Release of Foundation Models
- FlashAttention: Fast and Memory-Efficient Exact Attention with IO-Awareness
- Large Language Models Can Be Strong Differentially Private Learners
- Meet CoAuthor, an Experiment in Human-AI Collaborative Writing
- Borrowing from the Law to Filter Training Data for Foundation Models
The center builds and releases foundation models, code, and tools to improve the ecosystem.
CRFM engages with universities, companies, policymakers, and civil society to develop professional norms that govern the responsible development and deployment of foundation models.
Percy Liang, Director of the Center for Research on Foundation Models
Percy Liang is an associate professor of computer science at Stanford University and the director of the Center for Research on Foundation Models. His research spans many topics in machine learning and natural language processing, including robustness, interpretability, semantics, and reasoning. Percy’s awards include the Presidential Early Career Award for Scientists and Engineers (2019), IJCAI Computers and Thought Award (2016), an NSF CAREER Award (2016), a Sloan Research Fellowship (2015), and a Microsoft Research Faculty Fellowship (2014).
As the director of CRFM, he is leading Stanford’s efforts to make fundamental advances in the study, development, and deployment of foundation models through an interdisciplinary group of faculty, students, postdocs, and researchers.
Stanford Digital Economy Lab
Over the last academic year, the Digital Economy Lab has been focused on conducting research and hosting major events. The lab currently has more than 50 research projects in its portfolio.

Community Engagement and Public Outreach
To gather high-level feedback on its research areas, the lab hosted two advisory group meetings, which pointed the organization toward some key directions for growth and the expansion of its work. To build community at Stanford, the lab hosted two Stanford faculty roundtable discussions as well as a summer community BBQ in collaboration with HAI, the Golub Capital Social Impact Lab, and Stanford’s RegLab.
Measuring trends in artificial intelligence.
HAI and the AI Index Steering Committee published the 2022 AI Index report in March 2022. The latest edition included data from a broad set of academic, private, and nonprofit organizations as well as more self-collected data and original analysis than any previous edition. The authors included a variety of new data points to cover technical performance in reinforcement learning, the pricing of robotic arms, and artificial intelligence legislation.
The AI Index received positive press coverage, both around the time of the launch and throughout the rest of the academic year: highlights included pieces from publishers like IEEE Spectrum, Fast Company and Morning Brew. A number of prominent publications cited information contained in the report—TechCrunch, Fortune, Forbes and the Harvard Business Review among them.
Chess Software Engines: Elo Score
Progress in reinforcement learning, an important AI skill capability, can be captured by the performance of the world’s top chess software engines. Computers surpassed human performance in chess a long time ago, and since then have not stopped improving.
