My Journey Testing ML-Based Recommendations

Invited speaker

In today‘s era, machine learning (ML) is indeed the epicenter of software. Most software applications have ML-based components, with one such common component being recommendations. Tremendous effort is put into developing such recommendation systems. But have you ever wondered how these systems are tested? Much of the time, quality can take a backseat here as people perceive that It‘s machine learning, it cannot be tested. But is that really the case? If not, how can we break this myth?

Join Shivani Gaba as she shares her journey on exploring and testing recommendation systems, without having any prior experience of it. She‘ll reflect on her motivation, challenges faced and learnings. Not only will you get an introduction to the big picture and basic components of ML recommendation systems, but you‘ll also learn how product knowledge and thinking out of the box makes a difference. Shivani will leave you with tips, tricks, and techniques on how to create an impact on quality in such projects.

Key Takeaways:

  • Importance of testing ML-enabled applications
  • Advised practices of testing recommenders
  • How to apply product knowledge to test recommenders
  • Testability of ML recommender models
