Lower Bounds for Greedy Teaching Set Constructions

Spencer Compton, Chirag Pabbaraju, Nikita Zhivotovskiy

A fundamental open problem in learning theory is to characterize the best-case teaching dimension $TS_{m i n}$ of a concept class $C$ with finite VC dimensi…

Embedding Probability Distributions into Low Dimensional $ℓ_{1}$ : Tree Ising Models via Truncated Metrics

Moses Charikar, Spencer Compton, Chirag Pabbaraju

Given an arbitrary set of high dimensional points in $ℓ_{1}$ , there are known negative results that preclude the possibility of always mapping them to a low dimensional $ℓ_{1}$ s…
