IMDb data from Two Generations, from 1979 to 2019; Part one, Dataset Introduction and Preliminary Analysis

1 code implementation28 May 2020 M. Bahraminasr, A. Vafaei Sadr

As the lack of a comprehensive dataset was felt, we determined to do create a compendious dataset for the later analysis using the statistical methods and machine learning models; It comprises of various information provided on IMDb such as rating data, genre, cast and crew, MPAA rating certificate, parental guide details, related movie information, posters, etc, for over 79k titles which is the largest dataset by this date.

Cosmic String Detection with Tree-Based Machine Learning

no code implementations12 Jan 2018 A. Vafaei Sadr, M. Farhang, S. M. S. Movahed, B. Bassett, M. Kunz

We explore the use of random forest and gradient boosting, two powerful tree-based machine learning algorithms, for the detection of cosmic strings in maps of the cosmic microwave background (CMB), through their unique Gott-Kaiser-Stebbins effect on the temperature anisotropies. The information in the maps is compressed into feature vectors before being passed to the learning units.
