TALAN: Task-Aligned Latent Adaptation Networks for Targeted Post-Training of Large Language Models
arXiv:2606.06902v1 Announce Type: new Abstract: Targeted post-training aims to improve reasoning, math, and code without degrading strengths. Low-rank adapters are efficient but task-global; activation interventions are input-aware but often require separate probes, vectors, or inference-time steering. We introduce TALAN (Task-Aligned Latent Adaptation Networks), a sequence-conditioned latent side path inserted into a transformer's residual stream and co-trained with a low-rank adapter in one SFT loop. TALAN compresses the active sequence into latent memory, remixes it into token-level perturb
The rapid advancement and deployment of large language models create an immediate need for more efficient and targeted post-training methods to enhance specific capabilities without compromising generality.
Improving the targeted post-training of LLMs directly addresses the limitations of current fine-tuning approaches, which often lead to catastrophic forgetting or sub-optimal performance in specialized domains.
This research introduces a novel method to significantly enhance LLM performance in critical areas like reasoning, math, and code through more efficient and task-aligned adaptation, potentially lowering the barrier to deploying specialized LLMs.
