This week has been an absolute joy for me as the leader of the Healthy AI Lab! Two of my students, Anton Matsson (3rd from right) and Lena Stempfle (2nd from right), defended their theses and became the first PhD graduates under my supervision 🎉 You will both be sorely missed!

Prediction Models That Learn to Avoid Missing Values

Going to ICML next week? Find Anton and talk to him about our work on prediction models that learn to avoid missing values!

In a tree, features are used depending on the values and availability of other features. By penalizing reliance on missing values in computing predictions, we can learn trees that are unlikely to ask for a feature unless it is available (and predictive)

Fredrik Johansson @frejohk.bsky.social · May 8

In this work, we show that you can fit interpretable models that are unlikely to even *ask for* features that are missing at test time by learning to avoid using them in the first place. For trees, this is contextual...

If you want to fit an interpretable ML model like a tree or a GLM, how can you make sure that it's still accurate and interpretable when input features are missing at test time? Standard methods like imputation or missingness indicators tend to break one or the other...

No argument there—I'm pretty sure that's a different question though.

Clearly not but I was surprised at how many orals at NeurIPS were missing speakers too. Any chance of having reserve speakers? Sure, there is an honor in being awarded an oral but, as a conference-goer, having a 20-min gap in the schedule due to a missing speaker seems like a missed opportunity.

The first paper by Herman Bergström, Emil Carlsson, Devdatt Dubhashi, and me, explores how important context is to active preference learning from pairwise feedback: arxiv.org/abs/2405.03059

In the second, I develop a benchmark for evaluating estimators of causal effects. arxiv.org/abs/2405.16069

IncomeSCM: From tabular data set to time-series simulator and causal estimation benchmark

Evaluating observational estimators of causal effects demands information that is rarely available: unconfounded interventions and outcomes from the population of interest, created either by randomiza...

I'm currently at NeurIPS eager to talk about the two papers from my group:
* Active Preference Learning for Ordering Items In-and Out-of-sample (arxiv.org/abs/2405.03059)
* IncomeSCM: From tabular data set to time-series simulator and causal estimation benchmark (arxiv.org/abs/2405.16069)

Open for work!

Unfortunately, I just found out that all funding and grants for my 2025 projects are canceled.

Would love the opportunity to continue the musical journey started with #Ultros. Comfortable with #GameMusic #GameAudio. Retweets appreciated linktr.ee/ratvader
