Incremental construction of LSTM recurrent neural network

Long Short--Term Memory (LSTM) is a recurrent neural network that uses structures called memory blocks to allow the net remember significant events distant in the past input sequence in order to solve long time lag tasks, where other RNN approaches fail. Throughout this work we have performed experiments using LSTM networks extended with growing abilities, which we call GLSTM. Four methods of training growing LSTM has been compared. These methods include cascade and fully connected hidden layers as well as two different levels of freezing previous weights in the cascade case. GLSTM has been applied to a forecasting problem in a biomedical domain, where the input/output behavior of five controllers of the Central Nervous System control has to be modelled. We have compared growing LSTM results against other neural networks approaches, and our work applying conventional LSTM to the task at hand.Postprint (published version

Solid State Analog for He-McKellar-Wilkens Quantum Phase

In this letter we investigate the quantum dynamics of a quasiparticle in the presence of a charged screw dislocation submitted to a uniform magnetic field. Analysing the quantum scattering for this quasiparticle we observed the appearance of a topological quantum phase in the solution and demonstrate that this phenomenon is the solid state analog of the He-McKeller-Wilkens effect.Comment: 7 pages, epl styl

A IMPORTÂNCIA DO PENSAMENTO DE NIETZSCHE EM O ANTI-ÉDIPO PARA A FORMULAÇÃO DE UMA ECONOMIA POLÍTICA PRIMITIVA.

Pretendo neste artigo discutir alguns usos singulares que os pensadores Gilles Deleuze e Félix Guattari, em O Anti-Édipo, fazem da “segunda dissertação” da Genealogia da Moral de Friedrich Nietzsche no intuito de formular uma economia política das sociedades primitivas através do problema da dívida (relação credor-devedor) e da crueldade intimamente ligada. Gostaria também de minimamente apresentar como essas práticas foram essenciais para esconjurar a formação do Estado

Probing the Cosmic Distance Duality Relation with the Sunyaev-Zeldovich Effect, X-rays Observations and Supernovae Ia

The angular diameter distances toward galaxy clusters can be determined with measurements of the Sunyaev-Zel'dovich effect and X-ray surface brightness combined with the validity of the distance-duality relation, $D_L(z) (1 + z)^{2}/D_{A}(z) = 1$, where $D_L(z)$ and $D_A(z)$ are, respectively, the luminosity and angular diameter distances. This combination enables us to probe galaxy cluster physics or even to test the validity of the distance-duality relation itself. We explore these possibilities based on two different, but complementary approaches. Firstly, in order to constrain the possible galaxy cluster morphologies, the validity of the distance-duality relation (DD relation) is assumed in the $\Lambda$CDM framework (WMAP7). Secondly, by adopting a cosmological-model-independent test, we directly confront the angular diameters from galaxy clusters with two supernovae Ia (SNe Ia) subsamples (carefully chosen to coincide with the cluster positions). The influence of the different SNe Ia light-curve fitters in the previous analysis are also discussed. We assumed that $\eta$ is a function of the redshift parametrized by two different relations: $\eta(z) = 1 + \eta_{0}z$, and $\eta(z)=1 + \eta_{0}z/(1+z)$, where $\eta_0$ is a constant parameter quantifying the possible departure from the strict validity of the DD relation. The statistical analysis presented here provides new evidence that the true geometry of clusters is elliptical. We find that the two-light curve fitters (SALT2 and MLCS2K2) present a statistically significant conflict, and a joint analysis involving the different approaches suggests that clusters are endowed with an elliptical geometry as previously assumed.Comment: 33 pages, 15 figures, some typos corrected, accepted for publication in the Astronomy \& Astrophysic

The change in the profile served by public housing policies and the growth of Non-Use Assets(BNDU): indebtedness, the foreclosures of real estate and the greater impact on low-income populations

El crédito fue utilizado como herramienta de acceso a la vivienda en Brasil y la consecuencia de este fenómeno fue la pérdida de propiedades por endeudamiento. Se estudian los inmuebles embargados por la Caixa Econômica Federal (CEF) en los distritos de Campo Limpo y Vila Andrade en São Paulo, caracterizados, respectivamente, por una población de bajos y altos ingresos. La recolección de datos de los lanzamientos inmobiliarios de La Empresa Brasileira de Estudos de Patrimônio (Embraesp) hizo explícito El redireccionamiento de los recursos habitacionales del Programa Minha Casa Minha Vida (PMCMV) para mayores ingresos, hecho que excluyó la población de bajos ingresos Del acceso a la vivienda. A través de los datos de CEF sobre bienes no de uso (bienes adjudicados y en existencia), el objetivo es comparar el impacto de la adjudicación entre poblaciones con diferentes perfiles socioeconómicos. Con base en datos de Campo Limpo y Vila Andrade, se verificó que el mayor impacto ocurre en los ingresos más bajos.O crédito foi usado como ferramenta de acesso à moradia no Brasil, e a consequência desse fenômeno foi a perda de imóveis por endividamento. Estudam-se aqui os imóveis retomados pela Caixa Econômica Federal (CEF) nos distritos de Campo Limpo e Vila Andrade, em São Paulo, caracterizados respectivamente por população de baixa e alta renda. O levantamento de dados dos lançamentos imobiliários da Empresa Brasileira de Estudos de Patrimônio (Embraesp) explicitou o redirecionamento dos recursos habitacionais do Programa Minha Casa Minha Vida (PMCMV) para as maiores rendas, fato que excluiu a baixa renda do acesso à moradia. Por meio de dados da CEF acerca dos bens não de uso (imóveis retomados e em estoque), compara-se o impacto da retomada entre populações de perfis socioeconômicos diferentes. A partir dos dados de Campo Limpo e Vila Andrade, constatou-se que as rendas mais baixas sofrem mais impacto das retomadas.Credit was used as a tool for accessing housing in Brazil and the consequence of this phenomenon was the loss of real state to indebtedness. The foreclosures of real state by Caixa Econômica Federal (CEF) in the districts of Campo Limpo and Vila Andrade in São Paulo are studied, characterized, respectively, by a low and high income population. The data collected of the real estate launches of the Brazilian Patrimony Studies Company(Embraesp), explained the redirection of the housing resources of the My House My Life Program (PMCMV) to the higher incomes, a fact that excluded low income from access to home. Through the CEF data on Non-Use Assets (retaked and in-stock real state), the objective is to compare the impact of foreclosures amoung populations with different socioeconomic profiles. Data from Campo Limpo and Vila Andrade proved that the greatest impact of the foreclosures occurs in the lowest incomes
