BioTimnit Gebru is the founder and executive director of the Distributed Artificial Intelligence Research Institute (DAIR). Prior to that she was fired by Google in December 2020 for raising issues of discrimination in the workplace, where she was serving as co-lead of the Ethical AI research team. She received her PhD from Stanford University, and did a postdoc at Microsoft Research, New York City in the FATE (Fairness Accountability Transparency and Ethics in AI) group, where she studied algorithmic bias and the ethical implications underlying projects aiming to gain insights from data. Timnit also co-founded Black in AI, a nonprofit that works to increase the presence, inclusion, visibility and health of Black people in the field of AI, and is on the board of AddisCoder, a nonprofit dedicated to teaching algorithms and computer programming to Ethiopian highschool students, free of charge.
Community rooted, independent AI researchThe Distributed Artificial Intelligence Research Institute (DAIR) was launched in December 2021 by Timnit Gebru as a space for independent, community-rooted AI research, free from Big Tech’s pervasive influence. Gebru believes that the harms embedded in AI technology are preventable and that when its production and deployment include diverse perspectives and deliberate processes, it can be put to work for people, rather than against them. With DAIR, Gebru aims to create an environment that is independent from the structures and systems that incentivize profit over ethics and individual well-being. In this talk, Gebru will discuss why she founded DAIR and what she hopes this interdisciplinary, community-based, global network of AI researchers can accomplish. She will discuss the incentive structures that make it difficult to perform ethical AI research, and give examples of how DAIR is hoping to forge a different path.

AI to explore molecular space and fight pandemics and climate changeMachine learning research is expanding its reach, beyond the traditional realm of the tech industry and into the activities of other scientists, opening the door to truly transformative advances in these disciplines. In this lecture I will focus on two aspects, modeling and experimental design, that are intertwined in the theory-experiment-analysis active learning loop that constitutes a core element of the scientific methodology. Computers will be necessary to go beyond the currently purely manual research loop and take advantage of high-throughput experimental setups and large-scale experimental datasets. I will discuss methods related to active learning, reinforcement learning, generative modeling, Bayesian ML, amortized variational learning and causal discovery. I will discuss the notion of epistemic uncertainty and how to estimate it. I will motivate generative policies that can sample a diverse set of candidate solutions to a problem, be it for proposing new experiments or causal hypotheses. Finally, I will describe current research to help us with these questions based on a new deep learning probabilistic framework called GFlowNets and how we plan to apply these in areas of great societal need like the unmet challenge of antimicrobial resistance or the discovery of new materials to help fight climate change.

Computational psychology and psychological computation: How AI and Brain Sciences can help each otherThe rapidly developing field of computational psychology/psychiatry aims to bridge the gap between the “legacy” approaches still prevalent in mental health care that rely on primarily subjective self-reports and subjective evaluations by doctors - in a stark contrast to other scientific and medical fields where objective tests (e.g. blood work, X-ray, MRI) are typically used to provide an objective basis for diagnosis and prognosis. The promise of computational psychiatry is to bring psychological diagnosis to a more solid ground based on objective measurements, potentially including brain imaging, wearable sensor data, as well as statistical analysis of speech and text data - the are where modern AI techniques can prove highly useful, I will briefly mention some past and ongoing work by our group and collaborators in this directions, from developing more robust statistical models across brain imaging datasets, aiming at learning invariant features of a mental state or a person across varying setting, to transferring knowledge extracted across different data modalities, following recent advances in large-scale pretrained deep neural network models whose transfer capabilities appear to go far beyond what was previously considered possible. However, the road between AI and brain sciences is bidirectional: among many ways in which neuroscience, psychiatry and psychology can inspire novel AI approaches, the ability of an AI system to maintain “meaningful” dialog with a person, and reaching certain objectives of the dialog (e.g., application of AI in semi-automated therapy), can be considerably improved by importing certain practices and ideas from the therapeutic dialog into AI language models (I will briefly summarize our prior work on depression therapy dialogues). Finally, given the rapid advances in the capabilities of large scale models in the past 1-2 years, sometimes called a “scaling revolution” these days, also increase the importance of developing AI systems that are aligned with human values and can avoid harming humans while remaining useful to them - the blossoming field of AI Alignment (as a subfield of AI Safety, which, beyond alignment problem, includes robustness and interpretability of AI systems). The vast amount of practical knowledge from the fields of psychology and neuroscience, and from psychiatric therapy practice, can be clearly very advancing the AI Alignment field.

Visual self-supervision in the Post-Dataset EraStarting in the early 2000s, datasets have revolutionized computer vision, arguably turning it from an art form into a science. But now, 20 years later, is our infatuation with fixed visual datasets and their training/test splits starting to cause harm? In this talk, I will describe some of our efforts to go past the fixed dataset paradigm and toward a more natural continuous online learning regime, where the distinction between training and test data is more blurred. I will present some of our latest work on test-time training, as well as a comically simple approach to test-time visual prompting / visual analogies.

BioSara Beery will join MIT as an assistant professor in the Faculty of Artificial Intelligence and Decision-Making in EECS in September 2023 and is currently a visiting researcher at Google working on urban tree mapping across North America. She received her PhD in computing and mathematical sciences at Caltech in 2022, where she was advised by Pietro Perona. Her research focuses on building computer vision methods that enable global-scale environmental and biodiversity monitoring across data modalities, tackling real-world challenges including strong spatiotemporal correlations, imperfect data quality, fine-grained categories, and long-tailed distributions. She partners with nongovernmental organizations and government agencies to deploy her methods in the wild worldwide and works toward increasing the diversity and accessibility of academic research in artificial intelligence through interdisciplinary capacity building and education.
Mapping urban trees across North America with the Auto Arborist DatasetGeneralization to novel domains is a fundamental challenge for computer vision. Near-perfect accuracy on benchmarks is common, but these models do not work as expected when deployed outside of the training distribution. To build computer vision systems that solve real-world problems at global scale, we need benchmarks that fully capture real-world complexity, including geographic domain shift, long-tailed distributions, and data noise. We propose urban forest monitoring as an ideal testbed for studying and improving upon these computer vision challenges, while working towards filling a crucial environmental and societal need. Urban forests provide significant benefits to urban societies. However, planning and maintaining these forests is expensive. One particularly costly aspect of urban forest management is monitoring the existing trees in a city: e.g., tracking tree locations, species, and health. We introduce a new large-scale dataset that joins public tree censuses from 23 cities with a large collection of street level and aerial imagery, containing over 2.5M trees and 300 genera. This benchmark enables the exploration of automated urban forest monitoring across modalities and with respect to geographic distribution shifts, vital for such a system to be deployed at-scale.

Uncertainty-Aware Machine Learning for a Sustainable Food Supply ChainIn the United States, 30–50% of all the food produced is wasted, representing a massive environmental problem—food waste contributes to up to 25% of all greenhouse gas emissions. One of the main drivers of food waste is supply chain inefficiency. This talk describes (1) novel machine learning methods for reasoning under uncertainty and (2) their application to a real-world supply chain control system that significantly improves efficiency and reduces waste. Specifically, I will present improved methods for calibrated uncertainty estimation and planning algorithms that benefit from accurate model uncertainties. This research extends widely used uncertainty quantification methods and demonstrates that most existing planning algorithms can be improved via these methods. I will also describe how these algorithms are deployed in a real-world supply chain control system. This system is currently deployed across hundreds of supermarkets in the US (handling ~10% of US produce volume) and has led to waste reductions of up to 50%.
