Fr\"oberg's Conjecture for Quintics and Septics in Four Variables

Let $k$ be a field of characteristic zero and let $S=k[x_1,x_2,x_3,x_4]$. We prove Fr\"oberg's predicted Hilbert series for ideals generated by $r$ general forms of equal degree $d$ for every $r\geq1$ in each of the two cases $d=5$ and $d=7$. Relative to the classical cases $r\leq5$ and the equal-degree theorem through...

Single-Token Expected-Value Scoring for Cold-Start Candidate Ranking

A fine-tuned Small Language Model is fine-tuned with a hybrid ordinal regression loss combining a Mean Squared Error term, which preserves ordinal distance, with a categorical Cross-Entropy term, which sharpens class boundaries, which sharpens class boundaries.
