This paper aims to show the various types of data that contain in an intrinsically way fuzzy or imperfect data that are presented in the real world. A form of implementation is described that allows extending the capabilities of a database by using layers levels, emphasizing in the concept of inheritance. What is described is illustrated by an example applied to the Peruvian reality, which is shown with a certain level of detail.

Language identification is an elemental task in natural language processing, where corpus-based methods reign the state-of-the-art results in multi-lingual setups. However, there is a need to extend this application to other scenarios with scarce data and multiple classes to face, analyzing which of the most well-known methods is the best fit. In this way, Peru offers a great challenge as a multi-cultural and linguistic country. Therefore, this study focuses in three steps: (1) to build from scratch a digital annotated corpus for 49 Peruvian indigenous languages and dialects, (2) to fit both standard and deep learning approaches for language identification, and (3) to statistically compare the results obtained. The standard model outperforms the deep learning one as it was expected, with 95.9% in average precision, and both corpus and model will be advantageous inputs for more complex ta...

This dissertation investigates the potential improvement of volcanic eruption understanding and forecasting methods by using advanced data processing techniques to analyze large datasets at three target volcanoes (Piton de la Fournaise (PdlF) (France), Sabancaya, and Ubinas (Peru)). The central objective of this study is to search for possible empirical relationships between the pre-eruptive behavior of the accelerated increase in seismic activity using the Failure Forecast Method (FFM) and velocity variations measured by Coda Wave Interferometry (CWI), since both observations are reported to be independently associated with medium damage. The FFM is a deterministic method used to forecast volcanic eruptions using an empirical relationship of increased and accelerated evolution of an observable (e.g., volcano-seismic event rates). The event rates used with FFM in this study were generate...

One challenge in miRNA–genes–diseases interaction studies is that it is challenging to find labeled data that indicate a positive or negative relationship between miRNA and genes. The use of one-class classification methods shows a promising path for validating them. We have applied two one-class classification methods, Isolation Forest and One-class SVM, to validate miRNAs interactions with the ERBB2 gene present in breast cancer scenarios using features extracted via sequence-binding. We found that the One-class SVM outperforms the Isolation Forest model, with values of sensitivity of 80.49% and a specificity of 86.49% showing results that are comparable to previous studies. Additionally, we have demonstrated that the use of features extracted from a sequence-based approach (considering miRNA and gene sequence binding characteristics) and one-class models have proven to be a feasib...

A neural network is a mathematical model that is able to perform a task automatically or semi-automatically after learning the human knowledge that we provided. Moreover, a Convolutional Neural Network (CNN) is a type of sophisticated neural network that has shown to efficiently learn tasks related to the area of image analysis (among other areas). One example of these tasks is image segmentation, which aims to find regions or separable objects within an image. A more specific type of segmentation called semantic segmentation, makes sure that each region has a semantic meaning by giving it a label or class. Since neural networks can automate the task of semantic segmentation of images, they have been very useful for the medical area, applying them to the segmentation of organs or abnormalities (tumors). Therefore, this thesis project seeks to address the task of semantic segmentation of ...

Objective. To determine the level of burnout syndrome presented by university teachers during virtual classes. Methods. A simple descriptive design was used, the burnout syndrome was determined based on three dimensions: emotional fatigue, depersonalization and personal fulfillment. The population was made up of all the teachers of Universidad de Huánuco, 531 teachers during the 2020-II period. The instrument for collecting these data was based on the transparency section of the official website of Universidad de Huánuco. The sample was determined probabilistically by strata, resulting in a total of 223 teachers. Statistics used were descriptive, where summary measures were considered. Results. Regarding the emotional fatigue dimension, it was obtained that 46.3% of teachers presented low emotional fatigue and only 35.2% of teachers obtained a high level of emotional fatigue, in relati...

During the COVID-19 pandemic, virtual education played a significant role around the world. In post-pandemic Peru, higher education institutions did not entirely dismiss the online education modality. However, this virtual education system maintains a traditional teaching-learning model, where all students receive the same content material and are expected to learn in the same way; as a result, it has not been effective in meeting the individual needs of students, causing poor performance in many cases. For this reason, a framework is proposed for the adaptive learning of higher education students in virtual classes using the Cross-Industry Standard Process for Data Mining (CRISP-DM) and Machine Learning (ML) methodology in order to recommend individualized learning materials. This framework is made up of four stages: (i) Analysis of student aspects, (ii) Analysis of Learning Methodology...

Micro finance organizations play an important role since they facilitate integration of all social classes to sustained economic growth. Against this background, exponential growth of data, resulting from transactions and operations carried out with these companies on a daily basis, becomes imminent. Appropriate management of this data is therefore necessary because, otherwise, it will result in a competitive disadvantage due to the lack of valuable and quality information for decision-making and process improvement. Data Governance provides a different approach to data management, as seen from the perspective of business assets. In this regard, it is necessary that the organization have the ability to assess the extent to which that management is correct or is generating expected results. This paper proposes a data governance maturity model for micro finance organizations, which frames ...

This article analyzes the formation of a new working class in the development poles that were established in Patagonia and Amazonia during the 1960s and 1970s. The growth of industry required the influx of workers to these areas, but this does not imply that there were no workers there initially. However, the scale of the transformation that took place led to the development of what can be called a new class. This class included migrants from various areas who had few traditions and experiences in common and a history conditioned by industrialization dependent on state subsidies. We analyze how each working class grew and the forms of struggle and organization they developed. The study is based on a literature survey, journalistic sources, census data, and interviews with workers. Studying this process contributes to an understanding of similar dynamics in other countries, where experien...

This study defines and characterizes etno-racial self-identification patterns of the Peruvianpopulation employing the Encuesta Nacional de Hogares (Enaho) 2012. For this purpose, we have employed a module with questions recently added to this survey, in order to approach empirically to the notion of identity, combining the dimensions of native language, self-acknowledgment and the notion of indigenous population. The results are based on a latent classes analysis employing, at the same time, the information in this questions in order to identify four possible etnoracial identities. These identities are intertwined in the self-acknowledgment process with certain ancestors and customs, and also the one based on language. With the methodology and the data collected, we haven’t found evidence that point that ethnic identities are multiple and fluent. The ethnic identit...
