DATA MINING FOR THE IMPROVEMENT OF ELEARNING COURSES

Ph.D. Student: Enrique García
Advisors: Cristóbal Romero, Carlos de Castro
Abstract: This thesis proposes a system oriented to find, share and suggest the most appropriate modifications to improve the effectiveness of the course. We use an iterative methodology to develop and carry out the maintenance of web-based courses to which we have added a specific data mining step.

HYBRID AND CONSTRUCTIVE METAHEURISTICS: METHODS AND APPLICATIONS

Ph.D. Student: Francisco Javier Rodríguez
Advisors: Carlos García, Manuel Lozano
Abstract: The main objective of this thesis is the development of optimisation methods for black-box environments based on hybrid metaheuristics combining simulated annealing and evolutionary algorithms, as well as the application of hybrid and constructive metaheuristics for non-uniform parallel machines scheduling and quadratic minimum spanning tree problems.

HYBRID MODEL FOR THE RECOMMENDATION OF LEARNING OBJECTS

Ph.D. Student: Alfredo Zapata
Advisors: Cristóbal Romero, Manuel Emilio Prieto
Abstract: This thesis proposes a collaborative methodology for searching, selecting and rating LOs in a group. We have implemented this methodology into a hybrid recommendation system called DELPHOS, which is a framework to assist users in the single/individual personalised search for learning objects in repositories.

ANT PROGRAMMING FOR CLASSIFICATION RULE MINING. APPLICATIONS

Ph.D. Student: Juan Luis Olmo
Advisors: Sebastián Ventura, José Raúl Romero
Abstract:The main objective of this thesis is the development of automatic programming models based on ant colony optimization toh2 address classification problems.

GENETIC PROGRAMMING FOR MULTI-LABEL CLASSIFICATION

Ph.D. Student: José Luis Ávila
Advisors: Sebastián Ventura, Eva L. Gibaja
Abstract: The main objective of this thesis is the development of a series of genetic programming models to solve multilabel classification problems. To do it, we propose the development of a multi-label classification using a genetic programming approach that allows working with numerical, categorical and nominal data sets.

NEW CHALLENGES IN ASSOCIATION RULE MINING: AN APPROACH BASED ON GENETIC PROGRAMMING

Ph.D. Student: José María Luna
Advisors: Sebastián Ventura, José Raúl Romero, Cristóbal Romero
Abstract: This thesis involves a series of approaches for mining association rules by means of a grammar-guided genetic programming based methodology. The ultimate goal is to provide new algorithms that mine association rules in only one step and in a highly efficient way. The use of grammars enables the flexibility of the extracted knowledge to be increased. Grammars also enable obtaining association rules that comprise categorical, quantitative, positive and negative attributes to be mined.

NEW CLASSIFICATION MODELS THROUGH EVOLUTIONARY ALGORITHMS

Ph.D. Student: Alberto Cano
Advisors: Sebastián Ventura, Amelia Zafra
Abstract: The objective of this thesis is the development of classification models using evolutionary algorithms, focusing on the aspects of scalability, interpretability and accuracy in complex datasets and high dimensionality.

PREDICTING STUDENT FAILURE AND DROPOUT AT SCHOOL USING DATA MINING TECHNIQUES

Ph.D. Student: Carlos Márquez
Advisors: Sebastián Ventura, Cristóbal Romero
Abstract: This study proposes to predict school failure in secondary education by using DM and to detect the factors that most influence school failure in young students by using classification techniques.

NEW HYBRID LEARNING MODELS FOR MULTI-LABEL CLASSIFICATION AND LABEL RANKING

Ph.D. Student: Oscar Gabriel Reyes
Advisors: Sebastián Ventura
Abstract: This doctoral thesis is focused on the multi-label learning paradigm. Two problems were studied, firstly, improving the performance of the algorithms on complex multi-label data, and secondly, improving the performance through unlabeled data.

METAHEURISTIC MODELS TO THE DEVELOPMENT OF DECISION SUPPORT SYSTEMS IN SOFTWARE CONSTRUCTION

Ph.D. Student: Aurora Ramírez
Advisors: José Raúl Romero, Sebastián Ventura
Abstract: With this thesis, we plan to explore the synergies between the artificial intelligence and software engineering in order to define and solve new problems within the field of search-based software engineering (SBSE), especially those focused on early software conception and analysis.


ONGOING THESES

IMPROVING EDUCATIONAL PROCESS MINING DISCOVERING BY GROPING DATA ABOUT STUDENT’S INTERACTION WITH MOODLE

Ph.D. Student: Alejandro Bogarín
Advisors: Cristóbal Romero, Rebeca Cerezo
Abstract: In this thesis, we propose to use Educational Process Mining (EPM) techniques to discover, analyze and provide a visual representation of the complete educational process in order to make unexpressed knowledge explicit and to facilitate better understanding of the educational process.

TEXT MINING AND MEDICINE: AN APPROACH TO EARLY DISEASE DETECTION

Ph.D. Student: Mª del Carmen Luque
Advisors: Jose M. Luna, Sebastián Ventura
Abstract: The main objective of this thesis is to develop a system based on Text Mining capable of transforming the textual clinical information in Knowledge to support the health professional in making decisions that allow the early detection of a disease.

APPLICATION OF SCIENTIFIC WORKFLOWS TO DATA-INTENSIVE DOMAINS

Ph.D. Student: Rubén Salado
Advisors: José Raúl Romero
Abstract: The aim of this Ph.D. thesis is to bring the processing of large amounts of data closer to scientists, independently of their computation skills. To this end, it is necessary to develop new mechanisms that facilitate the use of data science techniques and technologies to computing non-experts.

NEW MULTI-LABEL CLASSIFICATION MODELS FOR PROBLEMS WITH HETEROGENEOUS DATA. AN ENSEMBLE-BASED APPROACH

Ph.D. Student: Jose María Moyano
Advisors: Eva L. Gibaja, Krzysztof J. Cios, Sebastián Ventura
Abstract: The main objective of this thesis is to develop supervised learning models based on ensembles for problems with more flexible data representation for both the input and output space, as well as their application to solve real problems.

AUTOMATIC DIAGNOSIS OF MELANOMA WITH MODERN MACHINE LEARNING TECHNIQUES

Ph.D. Student: Eduardo Pérez
Advisors: Óscar Reyes, Sebastián Ventura
Abstract: The main goal of this thesis is the development of modern machine learning methods for the automatic (or semi-automatic) diagnosis of melanoma at early stages. This type of skin cancer has an increasing incidence in white people, causing close to 90% of skin cancer mortality.
