Abstract

fetched live from OpenAlex

This study is intended for researchers (and doctoral students) interested in learning more on the use of machine learning methods in non-investment crowdfunding (i.e., reward- and donation-based). In particular, the study illustrates the insights that machine learning methods could provide on non-investment crowdfunding, for example, through data and information visualization, the ranking of features importance, and prediction assessment metrics. Specifically, I use four machine learning methods (gradient boosted decision trees, random forests, shallow neural networks, and support vector machines). As the literature shows, machine learning methods outperform classical regression models when the underlying relations are nonlinear. As such, the study offers some insights on the nonlinear relationships that could exist between the explanatory variables and the likelihood of success for art projects (e.g., threshold and Goldilocks effects). The study also offers some guidance to art project creators.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
