“…In recent years, researchers in the database community have been working on raising the level of abstractions of machine learning (ML) and integrating such functionality into today's data management systems [95,96], e.g., SystemML [25], SystemDS [8], Snorkel [71], ZeroER [91], TFX [5,9], Query 2.0 [92], Krypton [66], Cerebro [67], ModelDB [86], MLFlow [94], Deep-Dive [14], HoloClean [72], EaseML [1], ActiveClean [48], and NorthStar [47]. End-to-end AutoML systems [93,97,33] have been an emerging type of systems that has significantly raised the level of abstractions of building ML applications.…”
