Comparing and Tuning Machine Learning Algorithms to Predict Type 2 Diabetes Mellitus
Aguilera-Venegas, Gabriel; López-Molina, Amador; Galán-García, José Luis; Rojo-Martínez, Gemma (2022-06-13)The main goals of this work is to study and compare machine learning algorithms to predict the development of type 2 diabetes mellitus. Four classifi cation algorithms have been considered, studying and comparing the ... -
Computer Algebra-based RBES personalized menu generator
People have many constraints concerning the food they eat. These constraints can be based on religious believes, be due to food allergies or to illnesses, or can be derived just from personal preferences. Therefore, ... -
A Discrete-time Queueing System With Imperfect Information for the Server
Atencia-McKillop, Iván; Galán-García, José Luis; Aguilera-Venegas, Gabriel; Rodríguez-Cielos, Pedro; Padilla-Domínguez, Yolanda Carmen; Galán-García, María Ángeles[et al.] (2020-07-24)We consider a discrete-time Geo=G=1=1 system in which a customer that finishes its fi rst essential service may opt to abandon the system, to receive a second optional service or to place at the head of the queue in order ... -
A fast functional approach to personalized menus generation using set operations
The authors developed some time ago a RBES devoted to preparing personalized menus at restaurants according to the allergies, religious constraints, likes and other diet requirements as well as products availability. A ... -
Introducing probabilistic celular automata. A versatile extension of Game of Live
Aguilera-Venegas, Gabriel; Egea-Guerrero, Rocío; Galán-García, José Luis (2018-06-14)The "Game of life" model was created in 1970 by the mathematician Jonh Horton Conway using cellular automata. Since then, di erent extensions of these cellular automata have been used in many applications, such as car ... -
Making more flexible ATISMART+ model for traffic simulations using a CAS
Ramírez, Manuel; Gavilán, José Manuel; Aguilera-Venegas, Gabriel; Galán-García, José Luis; Galán-García, María Ángeles; Rodríguez-Cielos, Pedro[et al.] (2015-07-28)Traffic simulations usually require the search of a path to join two different points. Dijkstra’s algorithm [1] is one of the most commonly used for this task due to its easiness and quickness. In [2, 3] we developed an ... -
