   Determining feature importance for actionable climate change mitigation policies

   Romit Maulik, Junghwa Choi, Wesley Wehde et al. · 2020 · Autres statistiques · Résumé IA disponible

   Résumé scientifique

   Given the importance of public support for policy change and implementation, public policymakers and researchers have attempted to understand the factors associated with this support for climate change mitigation policy. In this article, we compare the feasibility of using different supervised learning methods for regression using a novel socio-economic data set which measures public support for potential climate change mitigation policies. Following this model selection, we utilize gradient boosting regression, a well-known technique in the machine learning community, but relatively uncommon in public policy and public opinion research, and seek to understand what factors among the several …

   Generative AI for Data Science 101: Coding Without Learning To Code

   Jacob Bien, Gourab Mukherjee · 2024 · Autres statistiques · Résumé IA disponible

   Résumé scientifique

   Should one teach coding in a required introductory statistics and data science class for non-major students? Many professors advise against it, considering it a distraction from the important and challenging statistical topics that need to be covered. By contrast, other professors argue that the ability to interact flexibly with data will inspire students with a lasting love of the subject and a continued commitment to the material beyond the introductory course. With the release of large language models that write code, we saw an opportunity for a middle ground, which we tried in Fall 2023 in a required introductory data science course in our school's full-time MBA program. We taught studen…

   How to survive the Squid Games using probability theory

   Elena Moltchanova, Miguel Moyers-González, Geertrui Van de Voorde et al. · 2024 · Autres statistiques · Pas encore résumé

   Résumé scientifique

   In this paper, we consider how probability theory can be used to determine the survival strategy in two of the ``Squid Game" and ``Squid Game: The Challenge" challenges: the Hopscotch and the Warships. We show how Hopscotch can be easily tackled with the knowledge of the binomial distribution, taught in introductory statistics courses, while Warships is a much more complex problem, which can be tackled at different levels.

   Synthesis of High-Resolution Load Profiles with Minimal Data

   Thomas Schnake, David Bauer · 2019 · Autres statistiques · Résumé IA disponible

   Résumé scientifique

   For the estimation of a new energy supply system it is an important to have high-resolution energy load profile. Such a profile is in general either not present or very costly to obtain. We will therefore present a method which synthesizes load profiles from minimal given data, but with maximal resolution. The general initial data setting includes month integrals and load profiles a few days. The resulting time series features all important properties to represent a real energy profile.
