Abstract
COVID-19 is the tip of the iceberg with many other unsolved biomedical problems, such as cancer early identification and finding side effects of new drugs. These problems seem to be independent of each other and have so far been tackled by different biologists. In this talk, I will argue that behind these different biomedical problems is the same computational challenge, that is, how to understand and predict in never-before-seen situations. In addition to powerful predictive models, what is really needed are tools that generalize well to new drugs, new diseases, and new cohorts. My talk will discuss novel machine learning methods developed to tackle two kinds of never-before-seen situations: never-before-seen class and never-before-seen cohort. I will first introduce how we classify samples into never-before-seen classes by embedding noisy and large-scale biomedical ontologies, resulting in new discoveries in protein functions, cell types, and rare diseases. Next, I will introduce our solution to understand and characterize a never-before-seen cohort. Instead of finding which features are important, we answer the question of why these features are important using a novel multiscale biomedical knowledge graph. This multiscale knowledge graph is constructed using millions of scientific papers and millions of experimental associations, providing up-to-date and scalable evidence for observations in our multiscale biomedical world.

![Open AI: considering the ethical upsides and downsides of Open AI development
Abstract:
In this talk, I will discuss the ethical upsides and downsides of releasing AI openly.
I will first present our FAccT’22 paper [1], where we interview contributors to an open source Deepfake tool about their sense of responsibility and agency to prevent harm. We show that open source licenses and norms combine with notions of technological inevitability and neutrality to lead contributors to disavow responsibility for harmful ways their tool is used.
I will then broaden to discuss other work examining AI openness, situated in the context of “Open”AI’s U-turn on openness. I will discuss benefits of AI openness, such as supporting open science, and enabling wider scrutiny for harms such as bias, and downsides, such as enabling the proliferation of powerful tools which can be used to harm.
I will then conclude by enumerating and advocating for a variety of “middle ground” approaches to AI openness, including methods of norm setting, ethical licenses, release gating, or hard technical restrictions, before opening up discussion for other ways of tackling this thorny problem.
