Problem

1. Do experiments studying the impact of merging criteria (single-link, centroid, average-link, furthest link) on the properties of the resulting cluster tree. Which leads to the tallest trees? The most balanced? How do their running times compare? Which method produces results most consistent with k-means clustering?

2. Experiment with the performance of different algorithms/data structures for finding the nearest neighbor of a query point q among n points in d dimensions. What is the maximum d for which each method remains viable? How much faster are heuristic methods based on LSH than methods that guarantee the exact nearest neighbor, at what loss of accuracy?
