Researchers have introduced "Reclaim Evaluation" to assess language models' memory capabilities, finding that a memory retaining incorrect conclusions is more detrimental than an empty one. This "brittle memory" phenomenon was observed across seven models, where incorrect memories led to confident wrong answers, while empty memories resulted in abstention. The study proposes a "source-first" policy, prioritizing the retention of recomputable sources over derived conclusions, which significantly improves correctability within a fixed budget. This approach was validated across multiple deployed memory systems and on real dialogue data like MultiWOZ, demonstrating its effectiveness in maintaining accuracy in memory-intensive tasks. AI
