Reproducibility Variable Result LLM Response
Research Type Theoretical In this work, we prove that this is indeed the case for low degree polynomials. We show that for the broadcast problem using any Markov chain on trees with N leaves, below the Kesten Stigum bound, any O(log N) degree polynomial has vanishing correlation with the root. Our result is one of the first low-degree lower bound that is proved in a setting that is not based or easily reduced to a product measure.
