Dr. Alex Best, of Harmonic discusses AI's struggles with technical
and ethical limitations like uninterpretable methods and a lack of
diverse datasets make facial recognition and medical software
dangerously biased. If algorithms output answers without little
explanation, how can one trust those results? Interpretability is a
prerequisite to replace the work of human researchers. But using AI
for formalizing mathematics offers some mitigation, Alex Best says.
"Instead of asking for an answer, you ask for an answer and a
machine-checkable proof that that answer is correct."

Dr. Kristen Lauter, director of FAIR (Fundamental AI Research)
Labs, Meta, North America, discusses how cryptographers are using
AI. Online, private information is secured using difficult-to-solve
math problems. Researchers must test those problems thoroughly to
be sure they are truly difficult - if hackers can solve the
problem, they'll have access to your information.

Dr. Po-Shen Loh of Carnegie Mellon University, discusses how AI is
changing the landscape of mathematics and looks ahead at what might
come. As algorithms have matured, mathematicians have embraced
computation as means to accelerate math discoveries. Researchers
integrate AI with "proof checking" tools, like the software Lean,
to avoid errors more quickly. According to Loh, this makes it
easier for large teams to collaborate and for peers to check each
other's discoveries for accuracy. According to a study in the
journal Nature, mathematicians anticipate that AI will guide human
intuition, and help to prove unsolved conjectures.

Dr. Abiy Tasissa of Tufts University, discusses the mathematics he
and colleagues used to study particle collider data, including
optimal transport and optimization. Collider physics often result
in distributions referred to as jets. Dr. Tasissa and his team used
"Earth Mover's Distance" and other mathematical tools to study the
shape of jets. "It is interesting for me to see how mathematics can
be applied to study these fundamental problems answering
fundamental equations in physics, not only at the level of
formulating new ideas, which is, in this particular case, a notion
of distance, but also how the importance of designing fast
optimization algorithms to be able to actually compute these
distances," says Dr. Tasissa.

Dr. Outi Tervo of Greenland Institute for Natural Resources, shares
how mathematics helps recommend speed limits for marine vessels,
which benefits narwhals and Inuit culture. Narwhals "can only be
found in the Arctic," said Outi Tervo, a senior scientist at GINR.
"These species are going to be threatened by climate change more
than other species that can live in a bigger geographical area."
The collaboration has already lobbied on behalf of the narwhals to
reduce the level of sea traffic in their habitat, after using
mathematical analysis to identify how noise from passing boats
changes the narwhals' foraging behavior.
