Knowledge Acquisition During Pre-training? Large Language Models Learn Better With Auxiliary Views

Read the original on arXiv AI →

The paper investigates how large language models acquire knowledge during pre‑training, proposing that auxiliary views—reformulations of knowledge—are causally beneficial. Experiments show that repetition is essential, paraphrasing helps only at smaller batch sizes, and reallocating tokens from repetition to auxiliary views improves learning even for factual recall. The study also finds that the benefit of auxiliary views does not depend on the teacher model’s strength, identifies specific knowledge types that aid learning, and explores mechanistic effects via layer‑wise biases and compression.

LMEnt: A Suite for Analyzing Knowledge in Language Models from Pretraining Data to Representations

LMEnt is a toolkit designed to study how language models acquire and represent world knowledge. It includes a richly annotated pretraining corpus, an improved entity-based retrieval method, and twelve pretrained models with numerous checkpoints. The suite enables controlled experiments linking entity mentions in training data to downstream knowledge performance, revealing how co-occurrence patterns influence learning and editing difficulty.
