Making nonlinear manifold learning models interpretable: The manifold grand tour
2015
Smooth nonlinear topographic maps of the data distribution to guide a Grand Tour visualisation.Prioritisation of data linear views that are most consistent with data structure in the maps.Useful visualisations that cannot be obtained by other more classical approaches. Dimensionality reduction is required to produce visualisations of high dimensional data. In this framework, one of the most straightforward approaches to visualising high dimensional data is based on reducing complexity and applying linear projections while tumbling the projection axes in a defined sequence which generates a Grand Tour of the data. We propose using smooth nonlinear topographic maps of the data distribution to…
Prostitution voluntary or forced. A contribution to the debate
2011
La tesis abolicionista de que nadie puede elegir libremente vender su cuerpo ha sido cuestionada por quienes reclaman el reconocimiento de derechos laborales para los trabajadores del sexo, lo cual ha dado lugar a una encendida polémica sobre el carácter voluntario o forzado de la prostitución. Los testimonios de veintitrés mujeres (incluyendo cinco ex prostitutas), recogidos mediante entrevistas en profundidad, sugieren que todas ellas están situadas en un punto intermedio del continuum que va desde la coerción criminal hasta la opción vocacional. Los pasajes relativos específicamente al itinerario de acceso a este mundo permiten distinguir tres tipos de prostitución en función del grado d…
Submersed in the water, buried in the ground: comparative studies on metal assemblages and single finds from french Iron Age non-funerary contexts (V…
2020
Metal hoards are emblematic discoveries of European protohistoric societies and therefore an extremely dynamic research theme. However, even though there are many synthetic studies concerning Bronze Age practices, they are much less frequent concerning Iron Age deposits. In fact, since 1995 (Kurz 1995), no synthetic inventory on this subject had been carried out despite the regular increase in the number of discoveries since the development and multiplication of preventive archaeological excavations. Under these conditions, it seemed important to update the data and this led to the completion of a master's degree on this subject in 2011 (Le Cozanet 2011). Since then, our research hasn‘t cea…
A grid representation for distributed virtual environments
2004
Fast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environments (DVE) very common nowadays. The architecture and behavior of these systems are very similar to new grid computing applications where concepts such as sharing and high scalability are extremely exploited. However, there are several key issues in these systems that should still be improved in order to design a scalable and cost-effective DVE system. One of these key issues is the partitioning problem. This problem consists of efficiently assigning clients (3-D avatars) to the arbiters (servers) in the system. As an alternative to the ad-hoc heuristic proposed in the l…
Energy-Efficient and Secure Resource Allocation for Multiple-Antenna NOMA with Wireless Power Transfer
2018
Non-orthogonal multiple access (NOMA) is considered as one of the promising techniques for providing high data rates in the fifth generation mobile communication. By applying successive interference cancellation schemes and superposition coding at the NOMA receiver, multiple users can be multiplexed on the same subchannel. In this paper, we investigate resource allocation algorithm design for an OFDM-based NOMA system empowered by wireless power transfer. In the considered system, users who need to transmit data can only be powered by the wireless power transfer. With the consideration of an existing eavesdropper, the objective is to obtain secure and energy efficient transmission among mul…
Compression-based classification of biological sequences and structures via the Universal Similarity Metric: experimental assessment.
2007
Abstract Background Similarity of sequences is a key mathematical notion for Classification and Phylogenetic studies in Biology. It is currently primarily handled using alignments. However, the alignment methods seem inadequate for post-genomic studies since they do not scale well with data set size and they seem to be confined only to genomic and proteomic sequences. Therefore, alignment-free similarity measures are actively pursued. Among those, USM (Universal Similarity Metric) has gained prominence. It is based on the deep theory of Kolmogorov Complexity and universality is its most novel striking feature. Since it can only be approximated via data compression, USM is a methodology rath…

Alain Badiou and the restart of the Idea of communism from Althusserianism, Lacanism and Maoism
2011
En el siguiente texto pretendemos mostrar cómo el fundamento de la teoría filosófica del pensador francés Alain Badiou tiene origen en su reflexión acerca de su práctica política iniciada a partir de los acontecimientos de mayo del 68 y que, tal y como reconocerá el propio Badiou en años posteriores, consistió en un recomienzo de la Idea de comunismo bajo la secuencia maoísta. De esta manera argumentaremos cómo para realizar esta reflexión el filósofo francés se apoyó en sus lecturas tempranas, tratando de sintetizar la teoría de causalidad estructural althusseriana, la teoría subjetiva lacaniana y la teoría dialéctica maoísta. Abstract: In the following text we intend to show that the basi…

Tight-binding study of the optical properties of GaN/AlN polar and nonpolar quantum wells
2009
The electronic structure of wurtzite semiconductor superlattices (SLs) and quantum wells (QWs) is calculated by using the empirical tight-binding method. The basis used consists of four orbitals per atom (sp3 model), and the calculations include the spin-orbit coupling as well as the strain and electric polarization effects. We focus our study on GaN/AlN QWs wells grown both in polar (C) and nonpolar (A) directions. The band structure, wave functions and optical absorption spectrum are obtained and compared for both cases.
