Defining Data Science [article]

Yangyong Zhu, Yun Xiong
2015 arXiv   pre-print
In the present paper, data science is defined as the science of exploring datanature.  ...  Data science is gaining more and more and widespread attention, but no consensus viewpoint on what data science is has emerged.  ...  Data science is here defined as follows: Data science is the theory, method, and technology of studying datanature. It has two main components.  ...

Defining Data Science by a Data-Driven Quantification of the Community

Frank Emmert-Streib, Matthias Dehmer
2018 Machine Learning and Knowledge Extraction  
This statistical model allows us to define the 'importance' of a field as its predictive abilities. Overall, our method provides an objective answer to the question 'What is data science?'.  ...  Furthermore, for decomposing the data science community into its major defining factors corresponding to the most important research fields, we introduce a statistical regression model that is fully automatic  ...  In contrast, in this paper we present a data-driven, quantitative approach. Interestingly, that means we are using methods from data science in order to define data science itself.  ...

Definability in Mining Incomplete Data

Jerzy W. Grzymala-Busse, Teresa Mroczek
2016 Procedia Computer Science  
Local definability is essential for data mining since a concept is locally definable if and only if it can be expressed by decision rules.  ...  In this paper we study local and global definability of incomplete data sets from the view point of decision rule induction.  ...  This idea is a basic tool used in determining definability of the relations used to describe incomplete data sets. Incomplete data sets are affected by missing attribute values for different reasons.  ...

Defining and Classifying Infrastructural Contestation: Towards a Synergy Between Anthropology and Data Science [chapter]

Christos Giovanopoulos, Yannis Kallianos, Ioannis N. Athanasiadis, Dimitris Dalakoglou
2020 IFIP Advances in Information and Communication Technology  
With this paper we apply a cross-disciplinary methodology in order to document and define the practices of this new wave of infrastructural contestation, taking Greece in the 2008-2017 period as the case  ...  Moreover, this ongoing synergy between data science and anthropology, although a work in progress, enables us to detect processes towards a more active citizen engagement with infrastructure.  ...  Having defined these six types of infrastructural contestation, according to our data and findings, we need to clarify a few points. First they are not mutually exclusive.  ...

Recent Advances in Σ-Definability over Continuous Data Types [chapter]

Margarita Korovina
2004 Lecture Notes in Computer Science  
The purpose of this paper is to survey our recent research in computability and definability over continuous data types such as the real numbers, real-valued functions and functionals.  ...  We prove Engeler's Lemma for Σ-definability over the reals without the equality test which relates Σ-definability with definability in the constructive infinitary language Lω 1 ω .  ...  In order to introduce the logical approach to computability over continuous data types we consider the following problems. Which data structures are suitable for representing continuous objects? 2.  ...
