A hybrid algorithm for Bayesian network structure learning with application to multi-label learning

We present a novel hybrid algorithm for Bayesian network structure learning, called H2PC. It first reconstructs the skeleton of a Bayesian network and then performs a Bayesian-scoring greedy hill-climbing search to orient the edges. The algorithm is based on divide-and-conquer constraint-based subroutines to learn the local structure around a target variable. We conduct two series of experimental comparisons of H2PC against Max-Min Hill-Climbing (MMHC), which is currently the most powerful state-of-the-art algorithm for Bayesian network structure learning. First, we use eight well-known Bayesian network benchmarks with various data sizes to assess the quality of the learned structure returned by the algorithms. Our extensive experiments show that H2PC outperforms MMHC in terms of goodness of fit to new data and quality of the network structure with respect to the true dependence structure of the data. Second, we investigate H2PC's ability to solve the multi-label learning problem. We provide theoretical results to characterize and identify graphically the so-called minimal label powersets that appear as irreducible factors in the joint distribution under the faithfulness condition. The multi-label learning problem is then decomposed into a series of multi-class classification problems, where each multi-class variable encodes a label powerset. H2PC is shown to compare favorably to MMHC in terms of global classification accuracy over ten multi-label data sets covering different application domains. Overall, our experiments support the conclusions that local structural learning with H2PC in the form of local neighborhood induction is a theoretically well-motivated and empirically effective learning framework that is well suited to multi-label learning. The source code (in R) of H2PC as well as all data sets used for the empirical tests are publicly available.Comment: arXiv admin note: text overlap with arXiv:1101.5184 by other author

Imagining Convivial Multilingualism: Practices, Ideologies and Strategies in Diidxazá/ Isthmus Zapotec Indigenous Language Education

This study documents practices relating to the use of Isthmus Zapotec or Diidxaza, an Indigenous language of Oaxaca, Mexico, in formal and non-formal education. Drawing on ethnographic monitoring and ethnography of language policy methodologies, I document, interpret, and ultimately engage in Isthmus Zapotec education with the aim of countering social inequalities produced through language hierarchies. Within the historical and socio-political context of the Isthmus of Tehuantepec where Isthmus Zapotec is spoken, I describe and categorize the actors, practices, and socio-political processes that currently constitute the educational language ecology. I draw on participant observation, interviews, photographs and documents collected during 17 months of ethnographic fieldwork and several subsequent visits in the Isthmus (2013-2015) in order to illustrate the linguistic landscape and the prominent practices in this domain. Increased official recognition for Indigenous languages in Mexico and state-level promotion of local languages are influencing some education practices, although exclusion of Isthmus Zapotec remains the norm. A variety of Isthmus Zapotec teachers, learners, and advocates are working to reverse this exclusionary legacy, however. The ideologies and social imaginaries of actors in two education sites are analyzed in-depth, illustrating a convivial multilingual paradigm through which teachers and learners of Isthmus Zapotec are creating inclusive communities of practice, in contrast to the exclusionary and manipulative norms in many social and educational spaces. Additionally the strategies of Isthmus Zapotec advocates across education contexts and social scales are compared, exploring how strategies of representing, connecting, and producing are employed to address language inequalities, with differing degrees of speed and visibility. I analyze my own strategies of engagement in Isthmus Zapotec education and discuss conceptual and methodological shifts in how I approach advocacy work in relation to marginalized languages. Endangered or minoritized language education will continue to hold different meanings for different actors from local to global levels; a multi-perspectival approach is necessary to develop new strategies and to support inclusive and convivial imaginaries of multilingualism in the Isthmus of Tehuantepec and other contexts of language inequality

Putting PIRLS to Use in Classrooms Across the Globe

This open access book provides teachers with approaches to strengthen reading comprehension instruction based on scientific research and evidence-based didactic principles. In this volume, the Progress in International Reading Study (PIRLS) framework is used to inform teachers about the skills and knowledge that students need to comprehend certain texts. The book gives practical guidance on how a teacher can help students to learn these skills, specifically, when teaching reading to multilingual students. Good practices from schools in five participating PIRLS countries—Chile, Chinese Taipei, England, Georgia, and Spain—are shared. A description of the schools’ education in reading comprehension is provided with practical tips and example lessons. These insights into daily reading education in multilingual classrooms across the globe can be an inspiration to teachers all over the world
