If you know me, perhaps the fact that even ICML recognised my reviewing skills should not surprise you. I'd like to take a moment, however, to rant that our reviews were of questionable quality #ICML #Reviewing

📢New Paper on Reward Modelling📢 Ever wondered how to choose the best comparisons when building a preference dataset for LLMs? Our latest paper revives classic statistical methods to do it optimally! Here’s a 🧵on how it works 👇 arxiv.org/abs/2502.04354

📢 Interested in LLM debating to come up with better solutions?📢 Our latest paper, “ACC-DEBATE: An Actor-Critic Approach to multi-agent Debate,” introduces new and simple framework for training a team of LLMs to debate. arxiv.org/pdf/2411.00053 See thread 🧵below👇

🌟 It’s a great honour that our work has been selected as a spotlight paper for #ICML2024 ! This work offers a new perspective on Domain Generalisation so check it out! Many thanks to collaborators @_anurags14 @shbouabid @krikamol!
😵‍💫What does it mean to generalise a model? Perhaps this should be defined by the model user rather than the model developer. In our latest #icml paper we study this fundamental problem and propose an imprecise learning framework for domain generalisation.

Happy to share that "A Kernel Test for Causal Association via Noise Contrastive Backdoor Adjustment" has just been published in JMLR! paper: jmlr.org/papers/v25/21-1409.… with @sejDino and @ItsAStatLife tl;dr New hypothesis test for causal effect under the backdoor criterion 1/6

such as post-double selection, a lasso-based method, tend to completely fail at detecting non-linear dependencies between treatment and control under confounding. In the binary setting, existing kernel tests tend to have incorrect size. 5/6

I’ve skipped probably 75% of the paper which includes insights on permutation tests, consistency of our test statistic, weight estimation and the appendix of course ;) Happy reading and feel free to drop me a line if you got any Qs! 6/6

Happy to be presenting Faster Fast and Free Memory Method (F^3M) at #NeurIPS2022 Hall J #1034. We take on kernel matrix vector multiplication (KMVM) at scale for tall and skinny data (n<=10^9, D<=7) on GPU in linear time and memory. neurips.cc/virtual/2022/post… #GPs #KeOps

Happy to be presenting Pref-SHAP with @Chau9991 at #NeurIPS2022 Hall J #905. We develop Shapley values for generalised preference models (GPM), which are preference models without the transitivity assumption (no rock paper scissor relationships). nips.cc/virtual/2022/poster/…

Moving on from explaining RKHS functions, tomorrow morning me and @robhu92 will be presenting our work on explaining preference models using Pref-SHAP at Hall J #905! nips.cc/virtual/2022/poster/… Come visit to know what insights we have learnt from explaining Pokémon battle data!

Interested in explaining kernel methods (or GP) with Shapley values? Or in using SVs as attribution priors in ERM? I’ve got you covered! Check out my poster on RKHS-SHAP at Hall J #433 tmrw from 4-6pm CST! nips.cc/virtual/2022/poster/… #NeurIPS2022 #ExplainableAI #KernelMethods

Me and @vdwild will be presenting GWI-net tmrw at poster session 1 #509 at #NeurIPS2022! We bridge VI in infinite-dimensional spaces with BDL, where GWI-net allows us to equip deep nets with uncertainty quantification analogous to that of GPs neurips.cc/virtual/2022/post…

Successfully defended my PhD thesis today! A heartfelt thanks to @tom_rainforth and Ricardo Silva for examining me! Feeling blessed to have had @sejDino, @ItsAStatLife and @nicholls_geoff as my supervisors. Thankful to all my colleagues and collaborators for their support!

Happy to share that both RKHS-SHAP (arxiv.org/abs/2110.09167) and Pref-SHAP (arxiv.org/abs/2205.13662) are now accepted at #NeurIPS2022! In RKHS-SHAP we utilise mean embeddings to explain kernel methods, while in Pref-SHAP we utilise RKHS-SHAP to explain preference models !
