Mixtures of SubExperts for Large Language Continual Learning

🚀 Introducing Mixtures of SubExperts (MoSEs): A Breakthrough in Continual Learning for LLMs

Adapting Large Language Models (LLMs) to a continuous stream of tasks is challenging - especially due to catastrophic forgetting. Current PEFT (Parameter-Efficient Fine-Tuning) methods face a clear trade-off:

- Reusing a single parameter set → High forgetting

- Assigning separate parameters per task → No forgetting but linear model growth and limited knowledge transfer

✨ Our Solution: Mixtures of SubExperts (MoSEs)

MoSEs is a novel continual learning framework designed to achieve minimal forgetting, efficient scalability, and effective knowledge reuse.

🔹 Sparse SubExpert Architecture

A sparse Mixture of SubExperts is integrated into transformer layers, guided by a task-specific routing mechanism.

🔹 Minimal Forgetting

Dedicated SubExperts preserve and isolate knowledge from previous tasks, reducing interference.

🔹 Efficient Knowledge Transfer

The router dynamically selects and combines previously learned sparse parameters to accelerate learning on new tasks.

🔹 Scalable Model Growth

Model capacity increases sublinearly, enabling substantial savings in memory and computation.

🏆 State-of-the-Art Results on the TRACE Benchmark

Our experiments demonstrate that MoSEs significantly outperforms existing continual learning techniques in:

1️⃣ Knowledge Retention (minimal forgetting)

2️⃣ Scalability across a large number of tasks

3️⃣ Overall efficiency in parameters and computation

MoSEs delivers SOTA performance with dramatically improved efficiency - redefining what’s possible in continual LLM adaptation.
