The Cheriton School of Computer Science is named for David R. Cheriton, who earned his PhD in Computer Science at the University of Waterloo in 1978. In 2005, Professor Cheriton made a transformational gift to the school that supports named chairs, faculty fellowships, and graduate scholarships.

When can we trust predictions based on random inputs when working with real-world data? I will introduce quality control algorithms, which accept random inputs while rejecting inputs for which a prediction is substantially wrong, with high probability. I will focus on checking whether permutation pattern frequencies in a given sequence are close to those predicted for i.i.d. data. A permutation pattern describes the relative order of entries in a subsequence. For patterns of length k, estimating their frequency on arbitrary inputs requires exponentially many queries. I will show that quality control for these predictions requires only polynomially many queries.
Based on joint work with Ronitt Rubinfeld and Madhu Sudan.
