Databricks has developed MemAlign, an open-source alignment framework integrated with MLflow, to enhance the evaluation of machine learning code generated by their Genie Code tool. Initial human expert annotations revealed significant discrepancies between LLM judges and human experts, with an average error of up to 0.68 on a 3-point scale. By utilizing MemAlign with approximately 50 labeled examples, Databricks successfully reduced the error rate by 74-89% on the most misaligned dimensions, demonstrating the framework's effectiveness in closing the gap between AI-generated code quality and expert standards. Further analysis indicated that both semantic and episodic memory components are crucial for these improvements. AI
