An improved version of my joint work with @sabinasloman and @samikaski on Statistical Learning Theory in the presence of severe Epistemic Uncertainty is on the ArXiV now! Let un know what you think :)

In the presence of noisy data, the learner faces epistemic uncertainty (EU) at test time which, in many cases, cannot be resolved on the basis of training data alone. What to do then? @sabinasloman, @samikaski and I tried to answer this in arxiv.org/abs/2505.23496 1/3

Epistemic Errors of Imperfect Multitask Learners When Distributions Shift

Uncertainty-aware machine learners, such as Bayesian neural networks, output a quantification of uncertainty instead of a point prediction. We provide uncertainty-aware learners with a principled...

Ending the tweet with the wisdom from our friend Johnny (taken from the London International Award: Chinese Creativity), which captures the spirit of our workshop particularly well.

🚀Are you looking for an axiomatic, error-free, and VERY fast method for feature attribution in kernel methods? Check out PKEX-Shapley: Product-Kernel Exact Shapley algorithm. Computing Shapley now goes from O(2^d) to just O(d^2). ⚡️ Joint work with @MajidMo80592063 @krikamol
