    Monte Carlo Dropout

    Reading time: 2 min.Editorially reviewed on:

    Definition

    Monte Carlo Dropout uses repeated, slightly altered model runs for uncertainty estimation.

    An approximation method for uncertainty estimation that activates dropout during multiple inference runs.

    Simply explained

    The model responds multiple times with partially disabled connections; differences provide clues about uncertainty.

    Why it matters in practice

    Helps realistically assess model quality, limits, and technical decisions.

    Example from business

    A model generates twenty predictions; their spread serves as an uncertainty signal.

    Limits and pitfalls

    • Treating spread as calibrated probability or overlooking runtime costs.

    Origin & history

    Gal and Ghahramani interpreted dropout in 2016 as approximate Bayesian inference.

    Use in mid-sized companies

    • Possible application: A model generates twenty predictions; their spread serves as an uncertainty signal.

    Frequently asked questions

    What does Monte Carlo Dropout mean?

    An approximation method for uncertainty estimation that activates dropout during multiple inference runs.

    Which mistakes should be avoided?
