Researchers have explored a phenomenon called Capability Enhancement Localization (CEL) in transformer-based language models. This concept investigates whether removing a small subset of attention heads can actually improve a model's performance on a specific task, rather than degrade it. Through empirical studies across various model families and theoretical analysis of simplified attention models, the work suggests that training dynamics can indeed concentrate conflicting features into particular heads, leading to performance gains on one task when those heads are ablated, even at a global optimum.
