I really liked Maytal Saar-Tsechansky’s perspective that we should not try to have the “best” AI to help guiding human decisions, but instead focus on developing AI that has complementary strengths and awareness of when to make recommendations to create value.

Interesting paper on estimating bond returns using graph neural networks at #informs2023. It turns the institutional bond holding into a network and develops a Temporal Bipartite Graph Neural Network (TBGNN) model to capture valuable information from connections for bond pricing.
