What Kind of Language is Easy to Language-Model Under Curriculum Learning?
Researchers are investigating how curriculum learning, a training approach that mimics human language acquisition by starting with simpler examples, interacts with the inductive biases of language models. The study bridges linguistic typology and machine learning by testing whether LMs trained on progressively complex sentences can reproduce real-world patterns in how languages structure grammar across the world's 7,000+ attested languages. This work matters because it reveals whether learning order shapes what linguistic patterns models naturally prefer, potentially explaining why certain word orders and feature combinations emerge reliably in both human languages and trained systems. The findings could inform both model design and our understanding of why language models exhibit particular structural biases.

ExplainerThe buried angle here is directionality: the researchers aren't just asking whether curriculum learning helps models learn faster, but whether training order actively shapes which structural patterns models prefer, potentially explaining cross-linguistic universals as artifacts of learning dynamics rather than data distribution alone.
This is largely disconnected from the recent applied and deployment-focused work on the site, including the MoRFI hallucination paper from April 29, which probes learned features in fine-tuned models from a mechanistic interpretability angle. That work asks what fine-tuning introduces; this paper asks what training order selects for. Both are probing the relationship between training procedure and model behavior, but at very different levels of abstraction. The curriculum learning paper sits closer to foundational cognitive science than to production ML, which means its payoff horizon is longer and its audience is narrower.
The key test is whether the typological patterns the models reproduce under curriculum learning actually match frequency distributions in real attested languages, not just the training corpus. If the team releases cross-linguistic evaluation results against a held-out typology database like WALS within the next year, that would give the core claim real traction.
