Workshop: Nearest Neighbors for Modern Applications with Massive Data: An Age-old Solution with New Challenges

How to stop worrying and learn to love Nearest Neighbors

Alexei Efros


Nearest neighbors is an algorithm everyone loves to hate.   It's too trivial, too brute-force, doesn't offer any insights.  In this talk, I will try to make you fall in love with the humble nearest neighbor.  First, I will discuss the use of nearest neighbor as an exceptionally useful baseline to guard against our field's natural bias in favor of elegant algorithms over data.  Then, I will discuss some scenarios when nearest neighbors is particularly useful in practice.
