Anchored SFT KL Divergence Fine Tuning: Unifying DFT and Trust Regions
Master anchored sft kl divergence fine tuning, combining probability-weighted loss with trust region sft lora and kl regularized supervised fine tuning.

Master experience replay catastrophic forgetting llm solutions with complementary learning systems and rehearsal buffer LoRA fine-tuning strategies.

Elastic Weight Consolidation (EWC) explained: how Fisher weight springs prevent catastrophic forgetting, why they struggle at LLM scale, and tools to try.

Collapsing reward, optimisation, and persistence into physical survival embraces reward hacking: any method that gets the reward is a valid adaptation.

Cherry-picking training data for peak performance can trap agents in dead environments, while sliding window buffers help prevent self-training collapse.

Cherry-picking training data for peak performance deletes behavioural variance and collapses agents; a sliding window buffer preserves generalisation.

Pass@1 fell to zero in our self-training loop while the agents improved: they had learned to use failing first attempts as probes. Why, and what to measure.

Data selection for fine-tuning in a self-training loop: training on the best data collapsed in our 13-generation study, while recent data kept improving.

Afterlife helps a continuous learning AI agent develop a unique personality and skills at weight level with LoRA adapters, not just a memory.md file.

Afterlife is an open-source Agent Skill and CLI tool that lets local LLMs nominate memories, train and test LoRA adapters, and activate or roll back updates.
