- The End of Theory: The Data Deluge Makes the Scientific Method Obsolete
In this paper, we substantiate our premise that statistics is one of the most important disciplines to provide tools and methods to find structure in and to give deeper insight into data, and the most important discipline to analyze and quantify uncertainty. We give an overview over different proposed structures of Data Science and address the impact of statistics on such steps as data acquisition and enrichment, data exploration, data analysis and modeling, validation and representation and reporting. Also, we indicate fallacies when neglecting statistical reasoning. Data Science as a scientific discipline is influenced by informatics, computer science, mathematics, operations research, and statistics as well as the applied sciences.
Could Big Data be the end of theory in science?
Growth of the open science movement has drawn significant attention to data sharing and availability across the scientific community. In this study, we tested the ability to recover data collected under a particular funder-imposed requirement of public availability. We assessed overall data recovery success, tested whether characteristics of the data or data creator were indicators of recovery success, and identified hurdles to data recovery. Field of research was the most important indicator of recovery success, but neither home agency sector nor age of data were determinants of recovery. While we did not find a relationship between recovery of data and age of data, age did predict whether we could find contact information for the grantee.

Big data is a field that treats ways to analyze, systematically extract information from, or otherwise deal with data sets that are too large or complex to be dealt with by traditional data-processing application software. Data with many fields columns offer greater statistical power , while data with higher complexity more attributes or columns may lead to a higher false discovery rate. Big data was originally associated with three key concepts: volume , variety , and velocity. The analysis of big data presents challenges in sampling, and thus previously allowing for only observations and sampling. Therefore, big data often includes data with sizes that exceed the capacity of traditional software to process within an acceptable time and value.
No more theories or hypotheses, no more discussions whether the experimental results refute or support the original hypotheses. Given the amount of scientific data available, is it now possible to dismiss the role of theoretical assumptions and hypotheses? Should this new mode of gathering information supersede the old way of doing research? However, Anderson is not the first to want to relegate hypotheses to a subordinate role. Deductive reasoning, he argued, is eventually limited because setting a premise in advance of an experiment would constrain the reasoning so as to match that premise.
A Tale of Two Crowds: Public Engagement in Plankton Classification
Complex network processes are known to be driven not only by pairwise interactions but also by the interactions of small groups of tightly connected nodes, sometimes called higher-order interactions. So, identifying these higher-order interactions becomes paramount to gain insight in the nature of such processes. While predicting pairwise nodal interactions links from network data is a well-studied problem, the identification of higher-order interactions higher-order links has not been fully understood. In this talk, we review several approaches that have been proposed for addressing this task and examine their respective limitations.
Illustration: Marian Bantjes "All models are wrong , but some are useful. So proclaimed statistician George Box 30 years ago, and he was right. But what choice did we have? Only models, from cosmological equations to theories of human behavior, seemed to be able to consistently, if imperfectly, explain the world around us. Until now.
The End of Theory: The Data Deluge Makes the Scientific Method Obsolete
Owing to the recent surge of interest in the age of the data deluge, the importance of researching data infrastructures is increasing. The open archival information system OAIS model has been widely adopted as a framework for creating and maintaining digital repositories. Considering that OAIS is a reference model that requires customization for actual practice, this paper aims to examine how the current practices in a data repository map to the OAIS environment and functional components. By examining their current actions activities regarding their work responsibilities and IT practices, they studied the barriers and challenges of archiving and curating qualitative data at ICPSR.
Kevin C. Elliott, Kendra S. Cheruvelil, Georgina M. Montgomery, Patricia A. Scientists have been debating for centuries the nature of proper scientific methods. Currently, criticisms being thrown at data-intensive science are reinvigorating these debates.
Клянусь, - сказал. Она смотрела на него с недоумением. - Надеюсь, это не уловка с целью заставить меня скинуть платье. - Мидж, я бы никогда… - начал он с фальшивым смирением. - Знаю, Чед. Мне не нужно напоминать.
Это не имеет никакого отношения к Попрыгунчику, - резко парировала. Вот это чистая правда, - подумал Джабба. - Послушай, Мидж, к Стратмору я не отношусь ни плохо ни хорошо. Ну, понимаешь, он криптограф. Они все, как один, - эгоцентристы и маньяки. Если им что нужно, то обязательно еще вчера. Каждый затраханный файл может спасти мир.
Стратмор мгновенно взвесил все варианты. Если он позволит Хейлу вывести Сьюзан из шифровалки и уехать, у него не будет никаких гарантий.
Ничего себе зрелище. - Он покачал головой и возобновил работу. Дэвид Беккер стоял в центре пустого зала и думал, что делать .
Я запустил антивирус, и он показывает нечто очень странное.
Он нужен мне немедленно. - Ты сошла с ума! - крикнул в ответ Хейл. - Я вовсе не Северная Дакота! - И он отчаянно забился на полу. - Не лги, - рассердилась Сьюзан. - Почему же вся переписка Северной Дакоты оказалась в твоем компьютере.
