Catastrophic Forgetting by Language models

To all the awesome experts in AI/ML out there. i need a favor. I realized there is a gap in Language Models (SLMs/LLMs) remembering the data continuously which is termed as ‘catastrophic forgetting’. To solve that problem I came up with an adapter called Constrained Residual Mixing Adapter (CRMA) that enables continual learning. I tested it on TinyLlama 1.1B and Mistral 7B — the result: -0.1% drift across 4 sequential domains. Essentially zero forgetting. CRMA: -0.1% drift. Naive: +351% forgetting. Same model, same data, same hardware. Holds at both 1.1B and 7B. No replay, no EWC, no KD needed. ● CRMA Modular vs Naive — Mistral 7B (4 sequential domains) ┌─────────┬────────────┬──────────────────┐ │ Task │ CRMA Drift │ Naive Forgetting │ ├─────────┼────────────┼──────────────────┤ │ Medical │ -0.2% │ +228% │ ├─────────┼────────────┼──────────────────┤ │ Legal │ -0.1% │ +593% │ ├─────────┼────────────┼──────────────────┤ │ Code │ -0.1% │ +233% │ ├─────────┼────────────┼──────────────────┤ │ Finance │ +0.0% │ — │ ├─────────┼────────────┼──────────────────┤ │ Average │ -0.1% │ +351% │ └─────────┴────────────┴──────────────────┘ Now the favor - If you’re interested in independently verifying these results, I’d love to hear from you. DM me and I’ll share what you need to reproduce it. Thank you. and best wishes
