A Deep Embedded Framework for Spitzoid Neoplasm Classification Using DNA Methylation Data

del Amor, Rocío; Colomer, Adrián; Monteagudo, Carlos; Garzón, María José; García-Giménez, José Luis; Naranjo Ornedo, Valeriana (IEEE, 2021-08-27)

[EN] Spitzoid melanocytic tumors (SMT) are a group of neoplasms that represent a formidable diagnostic challenge for dermatopathologists. DNA methylation (DNAm) is a welldefined epigenetic factor that has an important role ...
A deep embedded refined clustering approach for breast cancer distinction based on DNA methylation

del Amor, Rocío; Colomer, Adrián; Monteagudo, Carlos; Naranjo Ornedo, Valeriana (Springer-Verlag, 2021-07-31)

[EN] Epigenetic alterations have an important role in the development of several types of cancer. Epigenetic studies generate a large amount of data, which makes it essential to develop novel models capable of dealing with ...
Allying topology and shape optimization through machine learning algorithms

Dimensionality reduction by minimizing nearest-neighbor classification error

Villegas, Mauricio; Paredes Palacios, Roberto (Elsevier, 2011-03)

There is a great interest in dimensionality reduction techniques for tackling the problem of high-dimensional pattern classification. This paper addresses the topic of supervised learning of a linear dimension reduction ...
Dimensionality reduction methods for machine translation quality estimation

González Rubio, Jesús; Navarro Cerdán, José Ramón; Casacuberta Nolla, Francisco (Springer Verlag (Germany), 2013-12)

[EN] Quality estimation (QE) for machine translation is usually addressed as a regression problem where a learning model is used to predict a quality score from a (usually highly-redundant) set of features that represent ...
