Adaptive Moments are Surprisingly Effective for Plug-and-Play Diffusion Sampling

ICLR 2026poster

Guided diffusion sampling relies on approximating intractable likelihood scores, which introduces significant noise into the sampling dynamics. We propose using adaptive moment estimation to stabilize these noisy likelihood scores during sampling. Despite its simplicity, our approach achieves state-…

Pre-training Limited Memory Language Models with Internal and External Knowledge

ICLR 2026poster

Neural language models are black-boxes--both linguistic patterns and factual knowledge are distributed across billions of opaque parameters. This entangled encoding makes it difficult to reliably inspect, verify, or update specific facts. We introduce Limited Memory Language Models (LMLM), a new cla…

Self-Augmenting Retrieval for Diffusion Language Models

ICML 2026poster

Diffusion language models offer fast, parallel decoding via non-autoregressive generation and uncertainty-aware denoising, yet these properties remain underexplored for retrieval. We propose *Self-Augmenting Retrieval for Diffusion Language Models*, a dynamic framework that uses intermediate diffusi…

SpeechOp: Inference-Time Task Composition for Generative Speech Processing

ICLR 2026poster

While generative Text-to-Speech (TTS) systems leverage vast "in-the-wild" data to achieve remarkable success, speech-to-speech processing tasks like enhancement face data limitations, which lead data-hungry generative approaches to distort speech content and speaker identity. To bridge this gap, we…

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…

A Framework for Adapting Pre-Trained Language Models to Knowledge Graph Completion

EMNLP 2022main

Recent work has demonstrated that entity representations can be extracted from pre-trained language models to develop knowledge graph completion models that are more robust to the naturally occurring sparsity found in knowledge graphs. In this work, we conduct a comprehensive exploration of how to b…

Robust Knowledge Graph Completion with Stacked Convolutions and a Student Re-Ranking Network

ACL 2021long

Knowledge Graph (KG) completion research usually focuses on densely connected benchmark datasets that are not representative of real KGs. We curate two KG datasets that include biomedical and encyclopedic knowledge and use an existing commonsense KG dataset to explore KG completion in the more reali…
