Fast automatic two-stage nonlinear model identification based on the extreme learning machine

It is convenient and effective to solve nonlinear problems with a model that has a linear-in-the-parameters (LITP) structure. However, the nonlinear parameters (e.g. the width of Gaussian function) of each model term needs to be pre-determined either from expert experience or through exhaustive search. An alternative approach is to optimize them by a gradient-based technique (e.g. Newton’s method). Unfortunately, all of these methods still need a lot of computations. Recently, the extreme learning machine (ELM) has shown its advantages in terms of fast learning from data, but the sparsity of the constructed model cannot be guaranteed. This paper proposes a novel algorithm for automatic construction of a nonlinear system model based on the extreme learning machine. This is achieved by effectively integrating the ELM and leave-one-out (LOO) cross validation with our two-stage stepwise construction procedure [1]. The main objective is to improve the compactness and generalization capability of the model constructed by the ELM method. Numerical analysis shows that the proposed algorithm only involves about half of the computation of orthogonal least squares (OLS) based method. Simulation examples are included to confirm the efficacy and superiority of the proposed technique.

Authorizing a tradition: Theory, criticism and (self-) canonization in French Caribbean writing

As critics have noted, Antillean literature has developed in tandem with a strong (self-) critical and theoretical body of work. The various attempts to theorize Antillean identity (négritude, antillanité, créolité) have been controversial and divisive, and the literary scene has been characterized as explosive, incestuous and self-referential. Yet writers aligned with, or opposed to, a given theory often have superior visibility. Meanwhile writers who claim to operate outside the boundaries of theory, such as Maryse Condé, are often canny theoretical operators who, from prestigious academic or cultural positions, manipulate readers’ responses and their own self-image through criticism. While recent polemics have helped to raise the critical stock of the islands generally, they have particularly enhanced the cultural capital of Chamoiseau and Condé, whose literary antagonism is in fact mutually sustaining. Both writers, through a strong awareness of (and contribution to) the critical field in which their work is read, position themselves as canonical authors.

Writing the Dark Side of Travel

The travel experience filled with personal trauma; the pilgrimage through a war-torn place; the journey with those suffering: these represent the darker sides of travel. What is their allure and how are they represented? This volume takes an ethnographic and interdisciplinary approach to explore the writings and texts of dark journeys and travels. In traveling over the dead, amongst the dying, and alongside the suffering, the authors give us a tour of humanity’s violence and misery. And yet, from this dark side, there comes great beauty and poignancy in the characterization of plight; creativity in the comic, graphic, and graffiti sketches and comments on life; and the sense of profound and spiritual journeys being undertaken, recorded, and memorialized.

'Neo-Latin Writing in the British Isles'

This chapter seeks to identify cultural and generic trends and authorial methodologies that may serve to unify or to differentiate between the histories of neo-Latin literature in England, Scotland, Wales and Ireland. It considers ways in which Latin served to bridge horizontal spaces (both physical and metaphorical) between four British regions, between neo-Latin writers in Britain and their continental predecessors and peers, and between Latin and the respective vernacular(s). It also examines vertical spaces (both chronological and cultural) between the neo-Latin and the classical Latin text, and between the linear demarcations of ‘early modern’, ‘Augustan’ and ‘Romantic’. An assessment of links between nationhood and the neo-Latin text as evinced by anthologies, antiquarian and quasi-historical writing, is followed by examples of generic continuity and metamorphosis in the British neo-Latin pastoral, ode and epigram. The concluding sections offer two generic case-studies (neo-Latin epic and didactic) both of which, it is argued, engendered the birth of specifically British versions of the mock-heroic and mock-didactic.

Perceptions of authorial identity in academic writing among undergraduate accounting students: implications for unintentional plagiarism

The current study explores first, second and third year UK accounting students’ perceptions of authorial identity and their implications for unintentional plagiarism. The findings suggest that whilst all students have reasonably positive perceptions of their authorial identity, there is room for improvement. Significant differences in second year students’ perceptions were reported for some positive aspects of authorial identity. However, results for negative aspects show that second year students find it significantly more difficult to express accounting in their own words than first and third years. Furthermore, second years are significantly more afraid than first years that what they write will look unimpressive. Finally, the results for approaches to writing, which also have implications for unintentional plagiarism, revealed that students across all years appear to adopt aspects of top-down, bottom-up and pragmatic approaches to writing. Emerging from these findings, the study offers suggestions to accounting educators regarding authorial identity instruction.
