This work presents a novel approach to forecast streaming big time series based on nearest similar patterns. This approach combines a clustering algorithm with a classifier and the nearest neighbours algorithm. It presents two separate stages: offline and online. The offline phase is for training and finding the best models for clustering, classification and the nearest neighbours algorithm. The online phase is to predict big time series in real time. In the offline phase, data are divided into clusters and a (...) forecasting model based on the nearest neighbours is trained for each cluster. In addition, a classifier is trained using the cluster assignments previously generated by the clustering algorithm. In the online phase, the classifier predicts the cluster label of an instance, and the proper nearest neighbours model according to the predicted cluster label is applied to obtain the final prediction using the similar patterns. The algorithm is able to be updated incrementally for online learning from data streams. Results are reported using electricity consumption with a granularity of |$10$| minutes for 4-hour-ahead forecasting and compared with well-known online benchmark learners, showing a remarkable improvement in prediction accuracy.

The introduction of a new analytical method, due fundamentally to François Viète and René Descartes and the later dissemination of their works, resulted in a profound change in the way of thinking and doing mathematics. This change, known as process of algebrization, occurred during the seventeenth and early eighteenth centuries and led to a great transformation in mathematics. Among many other consequences, this process gave rise to the treatment of the results in the classic treatises with the new analytical method, (...) which allowed new visions of such treatises and the obtaining of new results. Among those treatises is the Arithmetic of Diophantus of Alexandria which was written, using the new algebraic language, by the French mathematician Jacques Ozanam, who in addition to profusely increasing the original problems of Diophantus, solved them in a general way, thus obtaining many geometric consequences. The work is handwritten, it has never been published, it has been lost for almost 300 years, and the known references show its importance. We will show that Ozanam’s manuscript was quoted as an important work on several occasions by others mathematicians of the time, among whom G. W. Leibniz stands out. Once the manuscript has been located, our aim in this article is to show and analyze this work of Ozanam, its content, its notation and its structure and how, through the new algebraic method, he not only solved and expanded the questions proposed by Diophantus, but also introduced a connection between the algebraic solutions and what he called geometric determinations by obtaining loci from the solutions.

Gregory Bateson is well known for defining information by stating “In fact what we mean by information – the elementary unit of information – is a difference which makes a difference…” This conceptual perspective has the merit of simplicity and generality. Simplicity, in addressing the complexity of information. Generality, in seeking applicability to any and every field of human experience. The purpose of this paper is to focus the applicability of this conceptual approach by Bateson and use it to perform (...) a calculation of taking the difference between two grey-level digital images that are shifted one relative to the other. The digital images take the place of the field of view that a human being would have access through her sense of vision at two different spatial/temporal instances. The results show that it is possible to highlight the edges of the objects under scrutiny, as well as to highlight other differences within the object. Bateson’s “difference that makes a difference” would seem to provide a first step in the elusive meaning making process of humans. (shrink)

La integración del Imperio Otomano y la progresista aparición, en su seno, de estados independientes a lo largo del siglo XIX trajo consigo la inevitable confluencia del espíritu ilustrado-romántico europeo, impulsor de las revoluciones en Europa y América, y el peso de la identidad nacional, arraigada en los esquemas patriarcales tradicionales. En ese exigente proceso de remodelación sociopolítica e ideológica, surgen discursos femeninos que, pese la escasa capacidad de maniobra, sitúan a la mujer en el epicentro del cambio y diseñan (...) una estrategia de lucha feminista.Presentamos dos discursos femeninos, los de la activista griega Kalirroe Parén (1861-1940) y la libanesa-palestina Mayy Ziyada (1866-1941), afincada en Egipto. Ambos se fundamentan en la actividad intelectual y literaria de sus creadoras, en los primeros y sólidos idearios feministas griego y árabe, y en la capacidad política de cambio de la mujer en un entorno hostil.

La interpretación y el texto mismo de unas líneas del parágrafo 94 del discurso Sobre la embajada fraudulenta de Demóstenes han sido objeto de discusiones, en particular la expresión τὴν πρώτην ἔφερον τοῦ φενακισμοῦ. En nuestra opinión, el problema se podría resolver si interpretamos que a lo largo de todo el pasaje se desarrolla una metáfora deportiva, en concreto relacionada con las λαμπαδηδρομίαι o carreras de relevos con antorchas. The text and the interpretation of some lines in Demosthenes' On the (...) false embassy has been discussed, particularly the expression τὴν πρώτην ἔφερον τοῦ φενακισμοῦ. In our opinion, the problem can be solved by understanding that in all the passage Demosthenes uses a sports metaphor that has to do with the λαμπαδηδρομίαι or torch relay races. (shrink)

Delusions are one of the most classical symptoms described in schizophrenia. However, despite delusions are often emotionally charged, they have been investigated using tasks involving non-affective material, such as the Beads task. In this study we compared 30 patients with schizophrenia experiencing delusions with 32 matched controls in their pattern of responses to two versions of the Beads task within a Bayesian framework. The two versions of the Beads task consisted of one emotional and one neutral, both with ratios of (...) beads of 60:40 and 80:20, considered, respectively, as the “difficult” and “easy” variants of the task. Results indicate that patients showed a greater deviation from the normative model, especially in the 60:40 ratio, suggesting that more inaccurate probability estimations are more likely to occur under uncertainty conditions. Additionally, both patients and controls showed a greater deviation in the emotional version of the task, providing evidence of a reasoning bias modulated by the content of the stimuli. Finally, a positive correlation between patients’ deviation and delusional symptomatology was found. Impairments in the 60:40 ratio with emotional content was related to the amount of disruption in life caused by delusions. These results contribute to the understanding of how cognitive mechanisms interact with characteristics of the task in the context of delusional thinking. These findings might be used to inform improved intervention programs in the domain of inferential reasoning. (shrink)

Obesity is a worldwide epidemic associated with severe health and psychological wellbeing impairments expressed by an increased prevalence of affective disorders. Emotional dysfunction is important due to its effect on social performance. The aim of the present narrative review is to provide a general overview of human research exploring emotional information processing in overweight and obese people. Evidence suggests that obesity is associated with an attenuation of emotional experience, contradictory findings about emotion recognition, and scarce research about automatic emotional information (...) processing. Finally, we made some concluding considerations for future research on emotional information processing in overweight and obese people. (shrink)

This article analyzes the construction of female subjectivity in the specific context of audiovisual cyberspaces in Spain dedicated to the struggle against violence against women. Looking at the YouTube channels of two virtual feminist communities that deal with violence against women, the authors analyze how the victim-subject is configured in terms of agency and activism. The authors adopt a multimodal model of studying the sign complexes of the videos as semiotic artifacts that produce meaning. Sign complexes are always engaged because (...) representation is never neutral because what is represented in sign is meant to realize the values and positions of those who make the sign. In this article, the authors understand feminist activism in the fight against violence targeting women as constructing in its discourse not only the activist process, but also the subject of this activism: the victim-subject of gender-based violence. The analysis engages in the discussion about the various ways in which this subject is interpellated by the audiovisual texts in terms of agency. As a result, this study proposes the necessity to devise new ways of articulating this subject as a political and agential one. (shrink)

This volume has 41 chapters written to honor the 100th birthday of Mario Bunge. It celebrates the work of this influential Argentine/Canadian physicist and philosopher. Contributions show the value of Bunge’s science-informed philosophy and his systematic approach to philosophical problems. The chapters explore the exceptionally wide spectrum of Bunge’s contributions to: metaphysics, methodology and philosophy of science, philosophy of mathematics, philosophy of physics, philosophy of psychology, philosophy of social science, philosophy of biology, philosophy of technology, moral philosophy, social and political (...) philosophy, medical philosophy, and education. The contributors include scholars from 16 countries. Bunge combines ontological realism with epistemological fallibilism. He believes that science provides the best and most warranted knowledge of the natural and social world, and that such knowledge is the only sound basis for moral decision making and social and political reform. Bunge argues for the unity of knowledge. In his eyes, science and philosophy constitute a fruitful and necessary partnership. Readers will discover the wisdom of this approach and will gain insight into the utility of cross-disciplinary scholarship. This anthology will appeal to researchers, students, and teachers in philosophy of science, social science, and liberal education programmes. 1. Introduction Section I.

Pathological tremor is a common but highly complex movement disorder, affecting ~5% of population older than 65 years. Different methodologies have been proposed for its quantification. Nevertheless, the discrimination between Parkinson’s disease tremor and essential tremor remains a daunting clinical challenge, greatly impacting patient treatment and basic research. Here, we propose and compare several movement-based and electromyography-based tremor quantification metrics. For the latter, we identified individual motor unit discharge patterns from high-density surface electromyograms and characterized the neural drive to a (...) single muscle and how it relates to other affected muscles in 27 Parkinson’s disease and 27 essential tremor patients. We also computed several metrics from the literature. The most discriminative metrics were the symmetry of the neural drive to muscles, motor unit synchronization, and the mean log power of the tremor harmonics in movement recordings. Noteworthily, the first two most discriminative metrics were proposed in this study. We then used decision tree modelling to find the most discriminative combinations of individual metrics, which increased the accuracy of tremor type discrimination to 94%. In summary, the proposed neural drive-based metrics were the most accurate at discriminating and characterizing the two most common pathological tremor types. (shrink)

Background: Heart rate variability (HRV) has been considered as a measure of heart-brain interaction and autonomic modulation, and it is modified by cognitive and attentional tasks. In cognitive tasks, HRV was reduced in participants who achieved worse results. This could indicate the possibility of HRV predicting cognitive performance, but this association is still unclear in a high cognitive load sport such as chess Objective: To analyse modifications on HRV and subjective perception of stress, difficulty and complexity in different chess problem (...) tasks. Design: HRV was assessed at baseline. During the chess problems, HRV was also monitored, and immediately after chess problems the subjective stress, difficulty and complexity were also registered. Method: A total of 16 male chess players, age: 35.19 (13.44) and ELO: 1927.69 (167.78) were analysed while six chess problem solving tasks with different level of difficulty were conducted (two low level, two medium level and two high level chess problems). Participants were classified according to their results into two groups: high performance or low performance. Results: Friedman test showed a significant effect of tasks in HRV indexes and perceived difficulty, stress and complexity in both high and low performance groups. A decrease in HRV was observed in both groups when chess problems difficulty increased. In addition, HRV was significantly higher in the high performance group than in the low performance group during chess problems. Conclusions: An increase in autonomic modulation was observed to meet the cognitive demands of the problems, being higher while the difficulty of the tasks increased. Non-linear HRV indexes seem to be more reactive to tasks difficulty, being an interesting and useful tool in chess training. (shrink)
