A classical problem asks us to find, for each element $A[i]$ of an array of integers, the position of the nearest smallest element. Similarly, we can ask about the dual problem: for each element of an array of integers $A[i]$, what is the position of the furthest smaller element? 

Indexing is a game of tradeoffs: Organize your data now and be rewarded with lower read latencies later. The question of whether, how, or when to organize has led to a proliferation of many different, often highly-specialized index structures.

We investigate a deep learning approach to classify emotions in group-level photos into three categories: (1) positive; (2) neutral; and (3) negative.
