Correlation length of the two-dimensional random field Ising model via greedy lattice animal
Jian Ding, Mateo Wirth
For the two-dimensional random field Ising model where the random field is given by i.i.d.\ mean zero Gaussian variables with variance , we study (one natural notion of) the c…
Crossing estimates from metric graph and discrete GFF
Jian Ding, Mateo Wirth, Hao Wu
We compare level-set percolation for Gaussian free fields (GFFs) defined on a rectangular subset of to level-set percolation for GFFs defined on the corresponding m…
Maximum of the integer-valued Gaussian free field
Mateo Wirth
We investigate the order of the maximum of the integer-valued Gaussian free field in two dimensions, and show that it grows logarithmically with the size of the box. Our treatment…
Percolation for level-sets of Gaussian free fields on metric graphs
Jian Ding, Mateo Wirth
We study level-set percolation for Gaussian free fields on metric graphs. In two dimensions, we give an upper bound on the chemical distance between the two boundaries of a macrosc…
Tree-Structured Boosting: Connections Between Gradient Boosted Stumps and Full Decision Trees
José Marcio Luna, Eric Eaton, Lyle H. Ungar +7
Additive models, such as produced by gradient boosting, and full interaction models, such as classification and regression trees (CART), are widely used algorithms that have been i…
