Attended an inspiring talk about new metrics for hockey players from Niklas Carlsson @research4fun and Patrick Lambrix @LiuPatla at #LINHAC 2022. Results indicate that some players overperform in high-pressure situations. Very interesting contrast to clutch hitting in baseball.

Honored to receive the Alexey Chervonenkis award for best paper at COPA 2021 together with @LofstromTuve and Henrik Boström from KTH for our paper "Calibrating multi-class models". #conformalprediction #machinelearning @JonkopingAI

Tonight at 6:30 I will give a public presentation (in Swedish) about AI. With inspiration from the epic and timeless music of @kraftwerk, I will discuss super intelligence, data as the new oil, ethics in AI and sports analytics. @JonkopingAI @JTHjkpg youtu.be/Pj6sFhHlO_g

On Wednesday, 11.15-12.30 I will give a tutorial about #VennPrediction at #COPA2020. It's free for everyone to attend on youtube.com/channel/UCu4dXkM… I can't help feeling that presenting VP at COPA is like giving Physics 101 with Einstein in the audience. @JonkopingAI @JTHjkpg

Listening to great presentations by @jibs_sweden students in the course Data analysis for decison making. The task here is churn prediction. @JonkopingAI

Gave a presentation about #AI for Jönköping Chamber of commerce. Promised #superintelligence and #eternalLife within 50 years...Also discussed more immediate matters; e.g., how companies should start their cognitive journey. @JonkopingAI @JTHjkpg

Yesterday, I gave a talk called “Getting the probabilities right” at #Ellos. Modern machine learning really should have learned more from the ES-era. Confidences should be based on probabilities, and the probabilities need to be well calibrated. #conformalPrediction @JonkopingAI

Attending the network conference of the #insidr graduate school at @hogskolaniboras Here phd-student Helena Löfström is talking about churn. @JonkopingAI

Acted as faculty opponent at Shiraz Farouq lic. defense at @HogskolanHstd Well done Shiraz, and nice to see #conformalPrediction being used in practice. @JonkopingAI

Dr @berilsirmacek explaining explainability at today’s #ai seminar. @JonkopingAI

Just presented our paper combining oracle coaching and #conformalPrediction at #dsaa2019 in #washingtonDc @JonkopingAI

Fantastic idea to co-locate #dsaa2019 with #Nats playoff games. This Swedish baseball fan really appreciating it. Tonight we trust in Max sending the series back to #LA. @JonkopingAI

Attending an interesting presentation at #dsaa2019 in Washington D.C. My colleague @ProfLavesson in @JonkopingAI is one of the co-authors.

Today I will give a tutorial about #conformalPrediction and #VennPredictors at #ICDATA19 in fabulous #LasVegas. @JonkopingAI

“No, #conformalPrediction is not magic, only mathematics.” @JonkopingAI #AI #ML #Sais2019

Explaining #conformalPrediction to an interested but sceptical fellow researcher at #Sais2019. @JonkopingAI

At #Sais2019 in beautiful #Ume. Just listened to presentations from SAIS award-winning master students. Interesting stuff in the areas of automated theorem proving and image transformation. @JonkopingAI #AI #ML

Presenting the paper Calibrating Probability Estimation Trees Using Venn-Abers Predictors at #SIAMSDM19 in Calgary today. @JonkopingAI

Gave a presentation at @pdbse about #AI. Talking about the singularity and eternal life, but also analyzing golf and Poker data. @JonkopingAI

Learning about @Upptech Jönköping Science Center. Keep up the good work so we get many talented science students in the future. @JonkopingAI
