Feature selection is a widely studied technique whose goal is to reduce the dimensionality of the problem by removing irrelevant features. It has multiple benefits, such as improved efficacy, efficiency and interpretability of almost any type of machine learning model. Feature selection techniques may be divided into three main categories, depending on the process used to remove the features known as Filter, Wrapper and Embedded. Embedded methods are usually the preferred feature selection method that efficiently obtains a selection of the (...) most relevant features of the model. However, not all models support an embedded feature selection that forces the use of a different method, reducing the efficiency and reliability of the selection. Neural networks are an example of a model that does not support embedded feature selection. As neural networks have shown to provide remarkable results in multiple scenarios such as classification and regression, sometimes in an ensemble with a model that includes an embedded feature selection, we attempt to embed a feature selection process with a general-purpose methodology. In this work, we propose a novel general-purpose layer for neural networks that removes the influence of irrelevant features. The Feature-Aware Drop Layer is included at the top of the neural network and trained during the backpropagation process without any additional parameters. Our methodology is tested with 17 datasets for classification and regression tasks, including data from different fields such as Health, Economic and Environment, among others. The results show remarkable improvements compared to three different feature selection approaches, with reliable, efficient and effective results. (shrink)

This multiple-case study examined the rationales and instructional strategies for teaching history of science of 16 instructors of a history of science course for undergraduate preservice teachers in the USA. Based on instructor syllabi, instructional materials, and instructor interviews, we conducted single-case and cross-case analyses to identify why they teach HOS, how they teach HOS, and what possible relationships might underlie instructor rationales and their instructional strategy choices for teaching HOS. We found 10 rationales in three overarching categories and 9 (...) active-learning instructional strategies. Moreover, we found that instructors with skills rationales implemented active-learning instructional strategies, whereas instructors who only cited knowledge rationales relied only on lectures and reading discussions. We discuss implications and recommendations for the design of HOS courses. (shrink)

This book explores the universe and its subsystems from the three lenses of evolutionary (diversifying), developmental (converging), and complex (adaptive) processes at all scales. It draws from prolific experts within the academic disciplines of complexity science, physical science, information and computer science, theoretical and evo-devo biology, cosmology, astrobiology, evolutionary theory, developmental theory, and philosophy. The chapters come from a Satellite Meeting, "Evolution, Development and Complexity" (EDC) hosted at the Conference on Complex Systems, in Cancun, 2017. The contributions will be peer-reviewed (...) and contributors from outside the conference will be invited to submit chapters to ensure full coverage of the topics. This book explores many issues within the field of EDC such as the interaction of evolutionary stochasticity and developmental determinism in biological systems and what they might teach us about these twin processes in other complex systems. This text will appeal to students and researchers within the complex systems and EDC fields.. (shrink)

Despite the salient experience of encoding threatening events, these memories are prone to distortions and often non-veridical from encoding to recall. Further, threat has been shown to preferentially disrupt the binding of event details and enhance goal-relevant information. While extensive work has characterised distinctive features of emotional memory, research has not fully explored the influence threat has on temporal memory, a process putatively supported by the binding of event details into a temporal context. Two primary competing hypotheses have been proposed; (...) that threat can impair or enhance temporal memory. We analysed two datasets to assess temporal memory for an in-person haunted house experience. In study 1, we examined the temporal structure of memory by characterising memory contiguity in free recall as a function of individual levels of heart rate as a proxy of threat. In study 2, we replicated marginal findings of threat-related increases in memory contiguity found in study 1. We extended these findings by showing threat-related increases in recency discriminations, an explicit test of temporal memory. Together, these findings demonstrate that threat enhances temporal memory regarding free recall structure and during explicit memory judgments. (shrink)

_Pasado de violencia política_ es una obra colectiva, conformada por diez ensayos de jóvenes investigadores e investigadoras, procedentes de distintas disciplinas: historia, ciencias políticas, antropología, arqueología, filosofía, filología, historia del arte. Esta convergencia responde al carácter eminentemente interdisciplinario del ámbito al que adscribe el libro ―lo estudios de memoria― y de la Asociación que da vida a este proyecto, _Memorias en Red_. Sin embargo, en este caso, la recolección de ensayos no apunta a establecer comparaciones interdisciplinarias sobre algún objeto específico (...) ―que es el enfoque más común de este tipo de obras― sino que su objetivo fundamental es discutir sobre la memoria en sí, sus dinámicas, funciones y manifestaciones. Persiguiendo este objetivo, el libro presenta un recorrido a través de objetos y contextos muy distintos: exhumaciones de fosas comunes, manifestaciones callejeras, ex centros de detención y tortura, prácticas de disidencia asociadas a la estética y la ética del cuerpo, procesamientos internacionales de derechos humanos y redes de activismo ciudadano.

Recent articles in Religious Studies have underscored the questions of whether Buddhism presents any empirical doctrines, and whether, if it does, such doctrines are false or vacuous. In what follows I want to sketch an interpretation of Buddhism according to which it does not offer doctrines which are empirically false, on the one hand, or trivially true on the other. In doing so I take my cue from an earlier, and by now classic, paper by H. H. Price. For the (...) exposition of Buddhism I take the Pali Nikāyas, the single most significant collection of texts in the Buddhist tradition. The particular doctrine which is the focus of discussion here is the kammavāda or ‘karma view’ of early Indian Buddhism, for it is the focus of much of the recent literature cited above and a doctrine which some have thought amenable to statement in empirical terms.

This paper responds to the issues raised by D. Chalmers by offering a research direction which is quite radical because of the way in which methodological principles are linked to scientific studies of consciousness. Neuro-phenomenology is the name I use here to designate a quest to marry modern cognitive science and a disciplined approach to human experience, thereby placing myself in the lineage of the continental tradition of Phenomenology. My claim is that the so-called hard problem that animates these Special (...) Issues can only be addressed productively by gathering a research community armed with new pragmatic tools for the development of a science of consciousness. I will claim that no piecemeal empirical correlates, nor purely theoretical principles, will really help us at this stage. We need to turn to a systematic exploration of the only link between mind and consciousness that seems both obvious and natural: the structure of human experience itself. In what follows I motivate my choice by briefly examining the current debate about consciousness at the light of Chalmer’s hard problem. Next, I outline the phenomenological strategy. Finally I conclude by discussing some of the main difficulties and consequences of this strategy. (shrink)

Geannoteerde briefwisseling van de twee geleerden over het vraagstuk van de evolutie.

The lambda calculus is a universal programming language. It can represent the computable functions, and such offers a formal counterpart to the point of view of functions as rules. Terms represent functions and this allows for the application of a term/function to any other term/function, including itself. The calculus can be seen as a formal theory with certain pre-established axioms and inference rules, which can be interpreted by models. Dana Scott proposed the first non-trivial model of the extensional lambda calculus, (...) known as $ D_{\infty }$, to represent the $\lambda $-terms as the typical functions of set theory, where it is not allowed to apply a function to itself. Here we propose a construction of an $\infty $-groupoid from any lambda model endowed with a topology. We apply this construction for the particular case $D_{\infty }$, and we see that the Scott topology does not provide enough information about the relationship between higher homotopies. This motivates a new line of research focused on the exploration of $\lambda $-models with the structure of a non-trivial $\infty $-groupoid to generalize the proofs of term conversion to higher-proofs in $\lambda $-calculus.

The role played by the movement of the ‘novatores’ determined the introduction of philosophical scientific European thought in Spain and was essential for the later development of Enlightment in Spain. Juan de Nájera represented the standard of modern thinker at the begining of the century and he intended to reconcile modern ideas with more traditional positions. He was a very example of a trend shared by most ‘novatores’ in early Eighteenth Century in Spain.

El concepto de público en Dewey permite reconciliar dos intuiciones en conflicto. Por un lado la idea de que la ciencia requiera de expertos entra en conflicto con la construcción de una sociedad democrática, y por la otra la idea de que las complejas sociedades del presente requieren para el desarrollo de la democracia de ciencia y tecnología. El concepto de público de Dewey permite superar ese conflicto en la medida en que permite superar la oposición tradicional en la filosofía (...) de la tecnología entre substantivistas y construccionistas.

In discussing questions of free will, Soviet philosophers fail to distinguish conditions from causes. This makes them unable to understand the very opponents they like to criticize.

Timothy Williamson, in various places, has put forward an argument that is supposed to show that denying bivalence is absurd. This paper is an examination of the logical force of this argument, which is found wanting.

This article is concerned with understanding continuity and stability in teaching, and their significance. It looks particularly at the work of Anthony Giddens on structure and agency, that of Martin Heidegger on the limits of discursive and theoretical analysis, and the communitarian strand within ethics. It applies this discussion to understandings of teachers’ work in the context especially of policy and agendas for change, arguing that continuity and the notion of a community of practitioners is critical to maintaining the distinctive (...) ethical quality of teaching.
