Causal Inference for Human-Language Model Collaboration

1 code implementation30 Mar 2024 Bohan Zhang, Yixin Wang, Paramveer S. Dhillon

A key challenge in answering this causal inference question is formulating an appropriate causal estimand: the conventional average treatment effect (ATE) estimand is inapplicable to text-based treatments due to their high dimensionality.

Filter Bubble or Homogenization? Disentangling the Long-Term Effects of Recommendations on User Consumption Patterns

no code implementations22 Feb 2024 Md Sanzeed Anwar, Grant Schoenebeck, Paramveer S. Dhillon

However, because of this assumption of a tradeoff between these two effects, prior work cannot develop a more nuanced view of how recommendation systems may independently impact homogenization and filter bubble effects.

A Risk Comparison of Ordinary Least Squares vs Ridge Regression

no code implementations4 May 2011 Paramveer S. Dhillon, Dean P. Foster, Sham M. Kakade, Lyle H. Ungar

We compare the risk of ridge regression to a simple variant of ordinary least squares, in which one simply projects the data onto a finite dimensional subspace (as specified by a Principal Component Analysis) and then performs an ordinary (un-regularized) least squares regression in this subspace.
