Combined Data Analysis Finds No Dark Matter Signal

ArXiv

Analysis

This paper is important because it combines data from two different experiments (ANAIS-112 and COSINE-100) to search for evidence of dark matter. The negative result, finding no statistically significant annual modulation signal, helps to constrain the parameter space for dark matter models and provides valuable information for future experiments. The use of Bayesian model comparison is a robust statistical approach.
Reference

“The natural log of Bayes factor for the cosine model compared to the constant value model to be less than 1.15... This shows that there is no evidence for cosine signal from dark matter interactions in the combined ANAIS-112/COSINE-100 data.”

r/MachineLearning

Analysis

This article describes a web application designed to simplify the comparison of time series forecasting models. The tool allows users to upload datasets, train baseline models (like linear regression, XGBoost, and Prophet), and compare their forecasts and evaluation metrics. The primary goal is to enhance transparency and reproducibility in model comparison for exploratory work and prototyping, rather than introducing novel modeling techniques. The author is seeking community feedback on the tool's usefulness, potential drawbacks, and missing features. This approach is valuable for researchers and practitioners looking for a streamlined way to evaluate different forecasting methods.
Reference

“The idea is to provide a lightweight way to: - upload a time series dataset, - train a set of baseline and widely used models (e.g. linear regression with lags, XGBoost, Prophet), - compare their forecasts and evaluation metrics on the same split.”
