Gaussian Mean Estimation Faces Information-Computation Gap

Researchers have identified an information-computation gap in estimating Gaussian means under a specific contamination model. This gap indicates that efficient algorithms require either significantly more samples than theoretically possible or incur exponential runtime. The study complements a lower bound in the Statistical Query model with an algorithm that nearly matches this tradeoff, providing a comprehensive understanding of the problem's complexity. AI
