Sequential Mining Classification

2017

Sequential pattern mining is a data mining technique that aims to extract and analyze frequent subsequences from sequences of events or items with time constraint. Sequence data mining was introduced in 1995 with the well-known Apriori algorithm. The algorithm studied the transactions through time, in order to extract frequent patterns from the sequences of products related to a customer. Later, this technique became useful in many applications: DNA researches, medical diagnosis and prevention, telecommunications, etc. GSP, SPAM, SPADE, PrefixSPan and other advanced algorithms followed. View the evolution of data mining techniques based on sequential data, this paper discusses the multiple …

Machine learning for rapid mapping of archaeological structures made of dry stones – Example of burial monuments from the Khirgisuur culture, Mongoli…

2020

11 pages; International audience; The present study proposes a workflow to extract from orthomosaics the enormous amount of dry stones used by past societies to construct funeral complexes in the Mongolian steppes. Several different machine learning algorithms for binary pixel classification (i.e. stone vs non-stone) were evaluated. Input features were extracted from high-resolution orthomosaics and digital elevation models (both derived from aerial imaging). Comparative analysis used two colour spaces (RGB and HSV), texture features (contrast, homogeneity and entropy raster maps), and the topographic position index, combined with nine supervised learning algorithms (nearest centroid, naive…

Deep learning to detect built cultural heritage from satellite imagery. - Spatial distribution and size of vernacular houses in Sumba, Indonesia -

2021

Abstract In Sumba Island – Indonesia, the implantation of vernacular houses, inside and outside traditional villages, is considered to be an efficient proxy for the on-going complex cultural transformations resulting from globalization. This study presents an easily reproducible workflow allowing buildings to be automatically detected from satellite imagery, demonstrating how modern computer vision methods based on deep learning can help in this task, which would be far too time-consuming when undertaken by hand. Eight deep learning architectures based on convolutional neural networks were compared in terms of ability to identify and locate precisely traditional houses from satellite images…

Computing methods for resilience: evaluating new building components in the frame of SECAPs

2019

Resilience represents a new important feature that the anthropic systems, and cities among them, are called to cope with. In fact, the increasing negative stresses to which urban contexts are exposed, and mainly the climatic pressures, call for the capability of adapting to these modifications and, possibly, to restore the ex-ante situations. The role of the buildings and their envelope components is of crucial importance to this aim. This paper analyses the features of resilience of the roofs of buildings by means of proper quantitative indexes. On purpose, the performances of green and cool roofs are compared. The possibility of adopting nonstructural solutions, like the windows shading d…

Abitare la nuova scuola. Embodied cognition e spazi di apprendimento.

2018

With the help of the new technology, schools could re-examine the role of the teacher and offer experiences of individual development within shared spaces to the young generation of digital natives. By redesigning the learning environment and incorporating elements of the Embodied Cognition Design, in line with the indications of the national curriculum, students will be well prepared for the future, with capabilities and responsibilities, and will tend towards the realization of the self as active, critical and aware citizens. But, with the pressure of new technologies, a profound restructuring of learning teaching methodologies is also required, incorporating new architectural arrangement…

The Evaluation of Social and Professional Life Competences of University Students Through Service-Learning

2021

The view previously held in the university regarding teaching-learning processes has changed significantly over the past few years. Undoubtedly, in the case of Europe, this change of pedagogical model has gone hand in hand with the creation of the European Higher Education Area (EHEA). Some of the pivotal areas of EHEA are the independent work of the individual student, the social dimension of learning, and the acquiring of skills, which are not reduced to the mere technical and/or subject matter knowledge. Generic competences and the so-called “soft skills” have also become important, given their significant contribution to the students’ academic, personal, social, and professional develop…

Sí, profe, pero? La enseñanza de la argumentación oral en el aula de E/LE

2020

Resumen: El trabajo que se presenta es una propuesta teórico-práctica sobre la argumentación oral en el aula de E/LE a partir de ciertos conceptos sobre la argumentación como los topoi o los tipos de argumentos. El estudio se divide en dos secciones: por una parte, se mostrarán las bases teóricas en la que se sustenta la propuesta y; por otra parte, se propondrán una serie de actividades para llevar a cabo en el aula de E/LE con el objetivo de mejorar las habilidades argumentativas de nuestro alumnado.
 Palabras clave: argumentación en la lengua, topoi, orientación argumentativa.

Argumentative Knowledge Construction in Online Learning Environments in and across Different Cultures: A Collaboration Script Perspective

2007

In recent years, information and communication technology has established new opportunities to participate in online learning environments around the globe. These opportunities include the dissemination of specific online learning environments as well as opportunities for learners to connect to online learning environments in distant locations. These dissemination and distance learning scenarios create potential challenges, however, in terms of the cultural differences in the internal scripts that learners of different cultures bring to these environments. This article considers these issues and challenges specifically for online environments focusing on argumentative knowledge constructio…

Argumentation Skills as Prerequisites for Collaborative Learning Among Finnish, French and English Secondary School Students.

2005

International audience; Argumentation skills of secondary school students were evaluated in Finland (n = 290), France (n = 54), and England (n = 41). The data were collected from 4 tasks comprising 7 variables. The results indicated that most of the students had correctly justified arguments and conclusions, and composed clear claims and relevant arguments. However, many students had difficulties in recognising the main claim and arguments for it in an expository text, and in commenting analytically on an argumentative text. Thus the students possessed the prerequisites for argumentative reasoning and writing but need further practice in analytical and critical reading.
