Graduated! Very grateful for my advisors, Mike Jordan and Ryan Tibshirani, who set the Pareto frontier for brilliance and kindness 🧠🩷 Next stop: MIT for a postdoc with @stats_stephen!

Come say hi at my @iclr_conf poster (Friday 10:30am, Pavilion 3 #316) to chat about prediction sets or why @PlantNetProject is my favorite plant identification app!

New paper: Conformal prediction for long-tailed classification🐒 arxiv.org/abs/2507.06867 🧑‍🌾 (plant enthusiast): Help me identify plants! 🤖 (existing conformal algs): Do you want sets that never include rare plants or sets that contain 100s of labels? 🧑‍🌾: Uhh… neither? A🧵(1/n)

My collaborator Joseph Salmon made a beautiful blog post about our paper, featuring an *interactive* recreation of a figure from Sadinle, Lei & Wasserman's iconic 2019 conformal prediction paper. Go check it out! Blog post: josephsalmon.eu/blog/long-ta…

All of these tools lead to strong empirical performance on PlantNet and iNaturalist. Check out the looooong tail; this is a tough setting! Some classes are left with 0 holdout examples for calibration (4/n)

This is joint work with Jean-Baptiste Fermanian & Joseph Salmon and inspired by discussions with the rest of the @PlantNetProject team (p.s. Check out their awesome plant identification app if you haven’t yet!🌱) (n/n)

📯 New work! Conformal Prediction Sets with Improved Conditional Coverage using Trust Scores. arxiv.org/abs/2501.10139 How useful are prediction sets that achieve 90% marginal coverage by failing on 10% cases that are challenging? Not very useful for clinicians who require uncertainty estimates for critical cases in diagnosis! Can we improve coverage where it matters most? 🧵 (1/n)

The greatest accomplishment of my statistics career has been winning this year’s @UCBStatistics T-shirt design competition with a @SFBART-inspired shirt designed w/ @aashen12! {stats nerds} ∩ {public transit nerds} ≠ ∅ 📉🚅

Sorry in advance if we missed topics! We tried to be as comprehensive as possible given the space constraints

📢New paper! Class-conditional conformal prediction with many classes arxiv.org/abs/2306.09335 👩‍⚕️ (doctor): “Give me uncertainty on the patient diagnosis.” 🤖(conformal): “The 95% prediction set is {normal}.” 👨🏻(patient): ☠️ How do you avoid this negative outcome? A 🧵(1/4)

A naive strategy is to split the data classwise and run conformal once per class. But with many classes/limited data, this gives bad results (big sets, etc.) In clustered conformal prediction, we cluster classes that have similar score distributions and pool their data! (3/4)
