SemPlan: Benchmarking Structured Semantic Planning for LLM-Based Queries over Enterprise Data
Bruno Santos Teixeira
Natural-language interfaces to enterprise data must translate underspecified requests into governed, executable behavior while controlling invalid queries, policy failures, cost, a…
Large margin classifier with graph-based adaptive regularization
Vítor M. Hanriot, Turíbio T. Salis, Luiz C. B. Torres +2
This paper introduces the use of per-class regularization hyperparameters in Gabriel graph-based binary classifiers. We demonstrate how the quality index used for regularization be…
Advancing Multinational License Plate Recognition Through Synthetic and Real Data Fusion: A Comprehensive Evaluation
Rayson Laroca, Valter Estevam, Gladston J. P. Moreira +2
Automatic License Plate Recognition is a frequent research topic due to its wide-ranging practical applications. While recent studies use synthetic images to improve License Plate…
Multiclass Graph-Based Large Margin Classifiers: Unified Approach for Support Vectors and Neural Networks
Vítor M. Hanriot, Luiz C. B. Torres, Antônio P. Braga
While large margin classifiers are originally an outcome of an optimization framework, support vectors (SVs) can be obtained from geometric approaches. This article presents advanc…
On zero-sum problems over metacyclic groups
Jun Seok Oh, Sávio Ribas, Kevin Zhao +1
Let be a finite group. A finite collection of elements from , where the order is disregarded and repetitions are allowed, is said to be a product-one sequence if its element…
The rings of (2060) Chiron: Evidence of an evolving system
C. L. Pereira, F. Braga-Ribas, B. Sicardy +54
The centaur (2060) Chiron has long been a candidate for hosting material in orbit, based on occultation and photometric and spectroscopic data. Here, we present a multichord stella…
