Noisy and corrupted measurements, commonly encountered as a result of unsupervised, automated data collection process, require new algorithms that produce reliable outcomes in this challenging framework. Discussing the influence of outliers on statistical procedures, P. Huber observed that "...the naturally occurring deviations from the idealized model are large enough to render meaningless the traditional asymptotic optimality theory." It is known that heuristic outlier removal procedures are bias-producing and lack rigorous justification (or require strong assumptions), as it is sometimes impossible to determine if an extreme observation appears due to an error, or is a feature of the data-generating mechanism. This motivates the study of robust estimators in the context of statistical learning theory.
Our goal is to encourage collaboration and knowledge sharing between theoretical computer scientists and mathematical statisticians by bringing them together at Luminy. Both communities possess unique visions, skills and expertise, we hope that merging these strength will advance the field and bring us closer to solving some of the key challenges.
