Researchers benchmarked five sub-1B language models and discovered that Full Fine-Tuning actively degrades performance on models under 300M parameters, causing accuracy to drop below zero-shot baselines. Parameter-Efficient Fine-Tuning (PEFT) methods like LoRA and DoRA prove necessary for stability, with task-specific strengths that outperform full fine-tuning and sometimes even match in-context learning on the smallest architectures.
Didact is a prototype system that integrates Australian defence reports, policy documents, and research publications into a unified knowledge graph to help policymakers discover defence capabilities faster.

Researchers studying lung CT imaging found that 2.5D CNNs provide the best balance of performance, stability, and computational efficiency for cancer screening compared to full 3D models or pure 2D approaches. The study challenges the assumption that 3D models are universally superior for volumetric medical imaging, revealing that 3D CNNs suffer from threshold instability while transformers produce unreliable degenerate predictions.
Researchers propose a mathematical framework for understanding how sparse autoencoders learn and represent concepts, formalizing concept learning as a set-alignment problem and establishing geometric conditions for neuron-level concept representation. The work connects concept learning to formal concept analysis, revealing that neuron interpretation involves complex many-to-many mappings rather than simple one-to-one relationships.

Researchers characterize the training dynamics of on-policy distillation (OPD), a technique used to improve large language model reasoning, revealing it operates in a distinct geometric regime compared to supervised fine-tuning and reinforcement learning. The study shows OPD exhibits 'subspace locking,' where cumulative updates rapidly converge to a narrow low-dimensional channel that is functionally sufficient for performance, suggesting OPD has unique training dynamics rather than existing as a simple intermediate between other training approaches.
