Leo Du (JHU) “Discrete Gradient-based Sampling with applications to Language Models”

October 21, 2024
When: October 21, 2024 @ 12:00 pm – 1:15 pm
Where: Hackerman Hall B17, 3400 N CHARLES ST, Baltimore, MD 21218

Abstract Gradient-based sampling algorithms are a cornerstone of modern Bayesian computation, widely used in applications ranging from probabilistic programming to diffusion models.  While these methods perform exceptionally well in continuous domains, extending them to discrete[…]

Roger Grosse (University of Toronto) “Probabilistic Inference in Language Models via Twisted Sequential Monte Carlo”

October 4, 2024
When: October 11, 2024 @ 12:00 pm – 1:15 pm
Where: Hackerman Hall B17, 3400 N CHARLES ST, Baltimore, MD 21218

Abstract Numerous capability and safety techniques of Large Language Models (LLMs), including RLHF, automated red-teaming, prompt engineering, and infilling, can be cast as sampling from an unnormalized target distribution defined by a given reward or[…]

Nate Robinson (JHU) “NLP for Related Languages”

September 30, 2024
When: October 7, 2024 @ 12:00 pm – 1:15 pm
Where: Hackerman Hall B17, 3400 N CHARLES ST, Baltimore, MD 21218

Abstract In the age of data- and capital-driven machine learning, the gap between technological advancements for high- and low-resource language varieties keeps growing, leaving many with the greatest need for language technologies without access to[…]

Helin Wang (JHU) “Solo Audio: Target Sound Extraction with Language-oriented Audio Diffusion Transformer”

September 23, 2024
When: September 27, 2024 @ 12:00 pm – 1:15 pm
Where: Hackerman Hall B17, 3400 N CHARLES ST, Baltimore, MD 21218

Abstract SoloAudio is an innovative diffusion-based generative model designed for target sound extraction (TSE). It trains latent diffusion models on audio, replacing the previous U-Net backbone with a skip-connected Transformer that operates on latent features.[…]
