Practical Marketplace Optimization at Uber Using Causally-Informed Machine Learning
Bobby Chen, Siyu Chen, Jason Dowlatabadi +15
Budget allocation of marketplace levers, such as incentives for drivers and promotions for riders, has long been a technical and business challenge at Uber; understanding lever bud…
Streaming motion in Leo I
Bodhisattva Sen, Moulinath Banerjee, Michael Woodroofe +2
Whether a dwarf spheroidal galaxy is in equilibrium or being tidally disrupted by the Milky Way is an important question for the study of its dark matter content and distribution.…
Isometric Graph Neural Networks
Matthew Walker, Bo Yan, Yiou Xiao +2
Many tasks that rely on representations of nodes in graphs would benefit if those representations were faithful to distances between nodes in the graph. Geometric techniques to ext…
Gluon Polarization Measurements from Correlated Probes
Matthew Walker
These proceedings show the preliminary results of the dijet longitudinal double spin asymmetry in polarized proton-proton collisions at GeV for the pseudo…
Dijet Cross Section and Longitudinal Double Spin Asymmetry Measurements in Polarized Proton-proton Collisions at \sqrt{s}=200 GeV at STAR
Tai Sakuma, Matthew Walker, the STAR Collaboration
These proceedings show the preliminary results of the dijet cross sections and the dijet longitudinal double spin asymmetries A_LL in polarized proton-proton collisions at \sqrt{s}…
A multi-epoch kinematic study of the remote dwarf spheroidal galaxy Leo II
Meghin Spencer, Mario Mateo, Matthew Walker +1
We conducted a large spectroscopic survey of 336 red giants in the direction of the Leo II dwarf galaxy using Hectochelle on the MMT, and conclude that 175 of them are members base…
