E-Scores for (In)Correctness Assessment of Generative Model Outputs
Guneet S. Dhillon, Javier González, Teodora Pandeva +1
While generative models, especially large language models (LLMs), are ubiquitous in today's world, principled mechanisms to assess their (in)correctness are limited. Using the conf…
A model-independent assessment of the late-time dark energy density evolution
Rayff de Souza, Agripino Sousa-Neto, Javier E. González +1
Combined measurements of Baryon Acoustic Oscillations (BAO) from the Dark Energy Spectroscopic Survey (DESI), the Cosmic Microwave Background (CMB) and Type Ia Supernovae (SN Ia),…
Exploring cosmological constraints on galaxy formation time
Agripino Sousa-Neto, Maria Aldinêz Dantas, Javier E. González +2
The Universe consists of a variety of objects that formed at different epochs, leading to variations in the formation time which represents the time elapsed from the onset of struc…
Evidence for dynamical dark energy from DESI-DR2 and SN data? A symbolic regression analysis
Agripino Sousa-Neto, Carlos Bengaly, Javier E. Gonzalez +1
Recent measurements of Baryon Acoustic Oscillations (BAO) from the Dark Energy Spectroscopic Survey (DESI DR2), combined with data from the cosmic microwave background (CMB) and Ty…
Beyond Flatland: A Geometric Take on Matching Methods for Treatment Effect Estimation
Melanie F. Pradier, Javier González
Matching is a popular approach in causal inference to estimate treatment effects by pairing treated and control units that are most similar in terms of their covariate information.…
