"We realized that to acquire quality talent, our recruitment process was in dire need of automation. Too many of our technicalteam were simply wasting hours conducting interviews that did not yield the desired results. For us the foremost criteria were to finda recruitment partner who could tick all the right boxes"

Rehana Nisar, Gartner,
Global Product & Services Recruitment Head

Suppose you clustered the dataset using some clustering algorithm. To check if the clustering is right or not you measured InterClusterDistance (IeCD) and IntraClusterDistance (IaCD). Let’s say = IeCDIaCD. Which of the following value of α suggests good clustering?

    • 0 < α < 1

    • α = 1

    • α > 1

    • α = 0


You are reviewing papers for the World’s Fanciest Machine Learning Conference, and you see submissions with the following claims. Which ones would you consider accepting?

    • My method achieves a training error lower than all previous methods!

    • My method achieves a test error lower than all previous methods! (Footnote: When regularization parameter λ is chosen so as to minimize test error.)

    • My method achieves a test error lower than all previous methods! (Footnote: When regularization parameter λis chose so as to minimize cross-validation error.)

    • My method achieves a cross-validation error lower than all previous methods! (Footnote: When regularization parameter λ is chosen so as to minimize cross-validation error.)
