The correct answer is C. Decrease the value of the epsilon parameter to increase privacy and reduce accuracy. Differential privacy tries to protect against the possibility that a user can produce an indefinite number of reports to eventually reveal sensitive data. A value known as epsilon measures how noisy, or private, a report is. Epsilon has an inverse relationship to noise or…

Question

You have a dataset that includes confidential data. You use the dataset to train a model. You must use a differential privacy parameter to keep the data of individuals safe and private. You need to reduce the effect of user data on aggregated results. What should you do?

Options

  • ADecrease the value of the epsilon parameter to reduce the amount of noise added to the data
  • BIncrease the value of the epsilon parameter to decrease privacy and increase accuracy
  • CDecrease the value of the epsilon parameter to increase privacy and reduce accuracy
  • DSet the value of the epsilon parameter to 1 to ensure maximum privacy

Explanation

Differential privacy tries to protect against the possibility that a user can produce an indefinite number of reports to eventually reveal sensitive data. A value known as epsilon measures how noisy, or private, a report is. Epsilon has an inverse relationship to noise or privacy. The lower the epsilon, the more noisy (and private) the data is. https://docs.microsoft.com/en-us/azure/machine-learning/concept-differential-privacy
