KC-Agent introduces a dual-process cognitive architecture designed to automate machine learning model updates in response to data drift, effectively balancing rapid pattern recognition with deliberate incremental improvements. By leveraging structured memory systems and atomic change principles, the system achieves state-of-the-art accuracy while significantly reducing execution time compared to existing agent-based approaches like CodeAct or ReAct. This research advances the field of automated ML maintenance by providing a reliable framework for handling real-world data degradation without costly re-computation.
KC-Agent: A Dual-Process Cognitive Architecture for Efficient ML Model Improvement
arXiv:2608.02351v1 Announce Type: new Abstract: Data drift poses significant challenges for machine learning systems in production, requiring continuous model updates to maintain performance. We present KC-Agent, a dual-process cognitive architecture for automated ML model improvement that combines fast pattern recognition (System 1) with deliberate incremental updates (System 2). Our approach implements structured memory systems enabling System 1 to leverage successful solutions previously discovered by System 2, achieving efficient pattern-based responses without costly re-computation. KC-Agent incorporates atomic change principles and rollback capabilities to ensure reliable, verifiable updates in production environments. We evaluate our method on five datasets including real-world NASA turbofan data with authentic temporal degradation and synthetic datasets with controlled drift scenarios. KC-Agent achieves state-of-the-art performance (76.8% accuracy) while maintaining optimal efficiency (13.2s execution time), outperforming established cognitive architectures: CodeAct (+2.4%), Tree of Thoughts (+3.6%), ReAct (+8.0%), and Reflexion (+8.9%). Consensus evaluation by a panel of state-of-the-art LLMs confirms superior strategic efficacy (8.33/10 Smartness score), significantly outperforming baseline agents. The knowledge consolidation mechanism delivers 91% speedup over the slow variant while maintaining higher accuracy. Our approach demonstrates both theoretical foundations and practical viability for cognitive-inspired automated ML improvement systems capable of handling complex real-world data drift scenarios.
