Generalization by symbolic abstraction in cascaded recurrent networks

Generalization performance in recurrent neural networks is enhanced by cascading several networks. By discretizing abstractions induced in one network, other networks can operate on a coarse symbolic level with increased performance on sparse and structural prediction tasks. The level of systematicity exhibited by the cascade of recurrent networks is assessed on the basis of three language domains. (C) 2004 Elsevier B.V. All rights reserved.

CONHECER PARA CONVERTER OU ALGO MAIS?: LEITURA CRÍTICA DAS ETNOGRAFIAS MISSIONÁRIAS DE HENRI-ALEXANDRE JUNOD E CARLOS ESTERMANN

Resumo: O colonialismo produziu diversos discursos sobre as culturas locais, sendo que o discurso dos missionários é uma de suas variantes e, por sua vez, neste discurso estão inclusas as etnografias missionárias. Apresentamos uma leitura crítica de duas etnografias missionárias produzidas nas até então colônias portuguesas, os territórios de Angola e Moçambique. A primeira, intitulada Usos e costumes dos bantos: a vida duma tribo sulafricana, cujo autor é o missionário Henri-Alexandre Junod (1863-1934); a segunda, intitulada Etnografia do sudoeste de Angola, cujo autor é o missionário Carlos Estermann (1896- 1976). Problematizamos a relação entre a ação missionária, o colonialismo português e as culturas locais dos territórios de Angola e Moçambique, através da análise destas etnografias missionárias. Destacamos que estas etnografias, além de apresentarem a riqueza das formas de vida das sociedades nativas, sinalizam como se efetivaram as negociações entre estes missionários em suas práticas de missionação e seus interlocutores nativos.

Cascaded Bayesian processes: an account of bias in orientation perception

Following adaptation to an oriented (1-d) signal in central vision, the orientation of subsequently viewed test signals may appear repelled away from or attracted towards the adapting orientation. Small angular differences between the adaptor and test yield 'repulsive' shifts, while large angular differences yield 'attractive' shifts. In peripheral vision, however, both small and large angular differences yield repulsive shifts. To account for these tilt after-effects (TAEs), a cascaded model of orientation estimation that is optimized using hierarchical Bayesian methods is proposed. The model accounts for orientation bias through adaptation-induced losses in information that arise because of signal uncertainties and neural constraints placed upon the propagation of visual information. Repulsive (direct) TAEs arise at early stages of visual processing from adaptation of orientation-selective units with peak sensitivity at the orientation of the adaptor (theta). Attractive (indirect) TAEs result from adaptation of second-stage units with peak sensitivity at theta and theta+90 degrees , which arise from an efficient stage of linear compression that pools across the responses of the first-stage orientation-selective units. A spatial orientation vector is estimated from the transformed oriented unit responses. The change from attractive to repulsive TAEs in peripheral vision can be explained by the differing harmonic biases resulting from constraints on signal power (in central vision) versus signal uncertainties in orientation (in peripheral vision). The proposed model is consistent with recent work by computational neuroscientists in supposing that visual bias reflects the adjustment of a rational system in the light of uncertain signals and system constraints.

Soliton switching using cascaded nonlinear-optical loop mirrors

We demonstrate multiple-peaked switching in a nonlinear-optical loop mirror and present an experimental investigation of device cascading in the soliton regime based on a sequence of two independent nonlinear-optical loop mirrors. Cascading leads to an enhanced switching response with sharper switching edges, flattened peaks, and increased interpeak extinction ratios. We observe that pulses emerging from the cascade retain the sech2 temporal profile of a soliton with minimal degradation in the spectral characteristics.
