When Data Is Scarce: Scaling Sparse Language Models with Repeated Training

Boqian Wu, Qiao Xiao, Patrik Okanovic +6

Scaling laws for dense LLMs under infinite data are well explored, but how sparsity interacts with limited data is not. In this work, we study sparse training in data-constrained r…

Memory-Efficient LLM Training with Dynamic Sparsity: From Stability to Practical Scaling

Qiao Xiao, Boqian Wu, Patrik Okanovic +6

Dynamic Sparse Training (DST) offers a promising paradigm for improving the training and inference efficiency of deep neural networks; however, we find that in large language model…

Confounder Detection via Treatment Intent: A New Observational Study Design

Drago Plecko, Patrik Okanovic, Torsten Hoefler +1

Understanding the effects of interventions is central to scientific progress, with randomized controlled trials (RCTs) regarded as the gold standard for causal inference in many ap…

Large Language Model Selection with Limited Annotations

Yavuz Durmazkeser, Patrik Okanovic, Andreas Kirsch +2

Choosing a Large Language Model (LLM) for a given task requires comparing many strong candidates, yet standard evaluation relies on costly annotations over fixed evaluation sets. T…

Epidemiology of Large Language Models: A Benchmark for Observational Distribution Knowledge

Drago Plecko, Patrik Okanovic, Shreyas Havaldar +2

Artificial intelligence (AI) systems hold great promise for advancing various scientific disciplines, and are increasingly used in real-world applications. Despite their remarkable…

BLaST: High Performance Inference and Pretraining using BLock Sparse Transformers

Patrik Okanovic, Sameer Deshmukh, Grzegorz Kwasniewski +8

The energy consumption of large-scale ML models is dominated by data movement, shuffling billions of parameters across memory hierarchies and data centers. Sparsification offers a…
