TimeSeriesExam: A time series understanding exam

Autor: Cai, Yifu, Choudhry, Arjun, Goswami, Mononito, Dubrawski, Artur

Large Language Models (LLMs) have recently demonstrated a remarkable ability to model time series data. These capabilities can be partly explained if LLMs understand basic time series concepts. However, our knowledge of what these models understand a

MOMENT: A Family of Open Time-series Foundation Models

Autor: Goswami, Mononito, Szafer, Konrad, Choudhry, Arjun, Cai, Yifu, Li, Shuo, Dubrawski, Artur

We introduce MOMENT, a family of open-source foundation models for general-purpose time series analysis. Pre-training large models on time series data is challenging due to (1) the absence of a large and cohesive public time series repository, and (2

The non-singular bouncing cosmology is an alternative paradigm to inflation, wherein the background energy density vanishes at the bounce point, in the context of Einstein gravity. Therefore, the non-linear effects in the evolution of density fluctua

BOSS Correlation Function Analysis from the Effective Field Theory of Large-Scale Structure

Autor: Zhang, Pierre, D'Amico, Guido, Senatore, Leonardo, Zhao, Cheng, Cai, Yifu

After calibrating the predictions of the Effective Field Theory of Large-Scale Structure against several sets of simulations, as well as implementing a new method to assert the scale cut of the theory without the use of any simulation, we analyze the
