Abstract

fetched live from OpenAlex

Understanding customer behaviour is a challenging problem. While the customer produces a large amount of data with each touch point, most of the proposed models focus on one data source in their predictive analysis approaches. This research proposes a customer profile model based on 360 customer view. To this end, we first model a simplified data model and the basic entities based on the existing models. Then, we perform extensive feature engineering techniques, including extracting new features and transforming features to enhance their behaviour in the predictive model. Through the experimentations, we show that the models based on graphs achieve good performance. To this end, we propose a graph-based neural network capable of multitasking without sacrificing the task's performance. We examine three tasks to predict customer intentions. The final results reveal that the set of features with customer information from different data sources positively influences the predictive algorithms' performance.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
