PBE is a new frontier in AI wherein the computer programs itself&#8212;the user provides input-output examples and the computer synthesizes an intended script. This is significant because 99% of computer users do not know programming. Even for programmers, this can provide a 10-100x productivity increase for many task domains.<\/p>\n<p>A killer application of PBE is in the space of data cleaning\/preparation since data scientists often spend up to 80% time wrangling data into a form suitable for learning models or drawing insights. In this video, Sumit illustrates how a data cleaning task, that Python programmers took an average of 30 minutes to finish, can be performed in 30 seconds by non-programmers using the PBE paradigm. In particular, PBE can help ingest a file into tabular format, split a column to extract constituent sub-fields, derive new columns, and suggest form entries.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sumit Gulwani founded the PROSE research and engineering team at Microsoft that develops programming-by-example (PBE) APIs and ships them through multiple Microsoft products.
