PhantomWiki: On-Demand Datasets for Reasoning and Retrieval Evaluation

ICML 2025poster

High-quality benchmarks are essential for evaluating reasoning and retrieval capabilities of large language models (LLMs). However, curating datasets for this purpose is not a permanent solution as they are prone to data leakage and inflated performance results. To address these challenges, we prop…

IncDSI: Incrementally Updatable Document Retrieval

ICML 2023poster

Differentiable Search Index is a recently proposed paradigm for document retrieval, that encodes information about a corpus of documents within the parameters of a neural network and directly maps queries to corresponding documents. These models have achieved state-of-the-art performances for docume…

Latent Diffusion for Language Generation

NeurIPS 2023poster

Diffusion models have achieved great success in modeling continuous data modalities such as images, audio, and video, but have seen limited use in discrete domains such as language. Recent attempts to adapt diffusion to language have presented diffusion as an alternative to existing pretrained langu…
