In “AI for modelling infectious disease epidemics”, we discuss how AI can help us in future pandemics. This is joint work with many colleagues, led by Moritz U G Kraemer and Samir Bhatt! nature.com/articles/s4158… Read it for free here: rdcu.be/eaxEw

Together with Manuel Gomez-Rodriguez, adishs, Krishna Gummadi, Goran Radanovic and Nina Grgić-Hlača, we have multiple open positions postdocs in AI, Computing, and Society at the MPI for Software Systems! Apply by May 13 via the new Max Planck Postdoc Program! mpg.de/en/max-planck-…

In Singapore for #ICLR2025! I'll be presenting our work on a causal methodology for evaluating LLMs (arxiv.org/abs/2502.01754) at the "Building Trust in LLMs" workshop on Monday. If you are working on causality, game theory and/or LLMs, let's grab a ☕️ during the conference!

The LLM API you use returns (and charges you for) 5 tokens. Did the LLM actually generate 5 tokens? Or is the provider overcharging you? 🤔 In arxiv.org/abs/2505.21627, led by Ander Artola Velasco, we argue (game-theoretically) for a change from pay-per-token to pay-per-character.

Giving this one a boost, since it was treated poorly by the algorithm. TL;DR: if you're using an LLM API, you could be getting overcharged and there's no way for you to know. See arxiv.org/abs/2505.21627 for more.

Explainable AI has long frustrated me by lacking a clear theory of what explanations should do. Improve use of a model for what? How? Given a task what's max effect explanation can have? It's complicated bc most methods are functions of features & prediction but not true state 1/

In Athens 🇬🇷 for the Greeks in AI symposium. Super excited to present our work on "Counterfactual Token Generation in LLMs" (bit.ly/4nMibs2) and see all the amazing work Greek people all over the world are doing on AI! If you are in Athens, let's meet! Next, heading to👇

Heading to Rio de Janeiro 🇧🇷 for UAI 2025 (UAI 2025) to present our tutorial with Tobias Gerstenberg and Manuel Gomez-Rodriguez on "Counterfactuals in Minds and Machines" on Monday. Looking forward to this! If you are in Rio, let's meet!

Life update: I’m excited to share that I’ll be starting as faculty at the Max Planck Institute for Software Systems(Max Planck Institute for Software Systems) this Fall!🎉 I’ll be recruiting PhD students in the upcoming cycle, as well as research interns throughout the year: lasharavichander.github.io/contact.html

Last week I had the pleasure of presenting a 2.5-hour tutorial on "Counterfactuals in Minds and Machines" at UAI 2025 in Rio 🇧🇷, prepared together with Manuel Gomez-Rodriguez and Tobias Gerstenberg . We've made all materials and references available here: learning.mpi-sws.org/counterfactual…
