Dropbox builds ML-powered content suggestions to surface relevant files for users

Searching through Dropbox content was tedious for users, who lacked a smart, contextual way to surface the files they needed without manual browsing.

Outcome

Replacing heuristics with an iteratively improved ML model significantly boosted the hit ratio and overall click-through rate for file suggestions.

What failed first

Initial rule-based heuristics showed unrelated files together, surfaced files accessed by background programs rather than users, and grew too complex to maintain; CTR also proved a poor and slow proxy for measuring model accuracy.
