Abstract:
We are at an inflection point where software engineering meets the data-centric world of big data, machine learning, and artificial intelligence.  As software development gradually shifts to the development of data analytics with AI and ML technologies, existing software engineering techniques must be re-imagined to provide the productivity gains that developers desire. We conducted a large scale study of almost 800 professional data scientists in the software industry to investigate what a data scientist is, what data scientists do, and what challenges they face. This study has found that ensuring correctness is a huge problem in data analytics. We argue for re-targeting software engineering research to address new challenges in the era of data-centric software development. We showcase a few examples of my group's research on debugging and testing of data-intensive applications: e.g., data provenance, symbolic-execution based test generation, and fuzz testing in Apache Spark. We then conclude with open problems in software engineering to meet the needs of AI and ML workforce.
