A new research paper explores the challenges of evaluating federated pre-training, a method for training models on distributed data without centralization. The study highlights that downstream fine-tuning on benchmarks like GLUE may not reliably reflect the quality of federated pre-training. Instead, direct next-token prediction during pre-training shows a stronger correspondence with the pre-training test perplexity, suggesting it is a more dependable evaluation signal. AI
IMPACT Suggests more reliable evaluation signals for federated pre-training, potentially improving model development and comparison.
