Our new #ICLR2024 paper shows how LLMs can successfully check their own change of thought reasoning without any fine-tuning or even examples, using an approach we call SelfCheck. Join me at poster 125 this afternoon to learn more Paper: openreview.net/forum?id=pTHf…

We propose alternative schemes that set the weights by optimizing a predictive objective, leveraging ideas from stacking and PAC-Bayes. They can be implemented as cheap post-processing steps on top of existing inferences and lead to more robust weights & better predictions. (5/5)

For probabilistic programs, one damning failure case is that the SLP weights tend to be overconfident, i.e. overly collapsing onto a single SLP. This means inferences might change drastically based on nominal changes in the data and will lead to sub-optimal predictions. (4/5)

Previous work showed that such programs can be decomposed into a mixture of straight-line programs (SLPs), each corresponding to a particular control flow path. The overall program posterior is then a weighted average over the local posteriors of the SLPs. (2/5)

The typical Bayesian NN setups treats all parameters stochastically. @MrinankSharma will shortly present our @aistats_conf "Notable Paper" on why this fundamental assumption is usually not justified and partially stochastic networks are often preferable proceedings.mlr.press/v206/s…

We've got really good at utilizing data. But methods for acquiring that data are often still rudimentary. Our new review paper shows how Bayesian experimental design has recently transformed to now provide a powerful mechanism to acquire data intelligently arxiv.org/abs/2302.14545
