Feed: R-bloggers. Author: rOpenSci - open tools for open science. Sharing data sets for collaboration or publication has always been challenging, but it’s become increasingly problematic as complex and high dimensional data sets have become ubiquitous in the life sciences. Studies are large and time consuming; data collection takes time, data analysis is a moving target, as is the software used to carry it out. In the vaccine space (where I work) we analyze collections of high-dimensional immunological data sets from a variety of different technologies (RNA sequencing, cytometry, multiplexed antibody binding, and others). These data often arise from clinical ... Read More

Feed: Teradata Blog. I’m pleased to announce that Teradata IntelliCloud – our as-a-service offering for analytics at scale – has been successfully vetted for compliance with the General Data Protection Regulation (GDPR). GDPR readiness for IntelliCloud applies to all our as-a-service deployment options: Microsoft Azure, Amazon Web Services, and Teradata Cloud (which is Teradata infrastructure in Teradata data centers). What exactly is GDPR, you ask? According to the internet’s most popular resource for crowd-sourced information (Wikipedia), GDPR is a regulation in European Union (EU) law on data protection and privacy for all individuals within the EU and the European Economic Area (EEA) ...

Feed: Blog. Author: Kim Brushaber; October is National Cybersecurity Awareness Month. In preparation for that, I thought I might take a moment to ponder some security issues that occured in the last week or two.  Recently, British Airways made the news for a data breach that occurred in August and September. The 380,000 customers affected are nowhere near as big as the $146 Million we saw last year with Equifax. However, British Airways will likely be the first major company to be investigated for their data breach after GDPR took effect in May of this year. All eyes are squarely focused ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: William Vorhies. Summary:  Purpose Built Analytic Modules (PBAMs) such as those for Fraud Detection represent a fourth way to practice data science, a new model for the good use of Citizen Data Scientists, and a new market for AI-first companies. It appears that data science has exited its age of exploration and entered into its age of consolidation and refinement.  That doesn’t mean that we aren’t making improvements but increasingly these tend to be incremental and not the big exciting break throughs we made through about 2016.  More like a mission ...

Feed: R-bloggers. Author: Ivan Svetunkov. Intro One of the features of functions of smooth package is the ability to work with intermittent data and the data with periodically occurring zeroes. Intermittent time series is a series that has non-zero values occurring at irregular frequency (Svetuknov and Boylan, 2017). Imagine retailer who sells green leap sticks. The demand on such a product will not be easy to predict, because green colour is not a popular colour in this case, and thus the data of sales will contain a lot of zeroes with seldom non-zero values. Such demand is called “intermittent”. In ... Read More

Feed: R-bloggers. Author: business-science.io - Articles. Artificial intelligence (AI) has the potential to change industries across the board, yet few organizations are able to capture its value and realize a real return-on-investment. The reality is that the transition to AI and data driven analysis is difficult and not well understood. The issue is twofold, first, the necessary technology to complete such a task has only recently become mainstream, and second, most data scientists are inexperienced in their respective industries. However, with all the uncertainty surrounding this topic, one hedge fund has managed to navigate through these challenges and accomplish what ... Read More

Feed: R-bloggers. Author: statcompute. In the post (https://statcompute.wordpress.com/2018/09/15/how-to-avoid-for-loop-in-r), I briefly introduced the idea of vectorization and potential use cases. One might be wondering why we even need the Vectorize() function given the fact that it is just a wrapper and whether there is any material efficiency gain by vectorizing a function. It is true that the Vectorize() function is not able to improve the efficiency of any function itself that is wrapped around, e.g. vectorized. However, the vectorization can change the input format of a function that normally consumes scalar inputs before being vectorized and therefore would improve the processing ... Read More

Feed: R-bloggers. Author: Dr. Shirin Glander. Today I am very happy to announce that during my stay in London for the m3 conference, I’ll also be giving a talk at the R-Ladies London Meetup on Tuesday, October 16th, about one of my favorite topics: Interpretable Deep Learning with R, Keras and LIME. You can register via Eventbrite: https://www.eventbrite.co.uk/e/interpretable-deep-learning-with-r-lime-and-keras-tickets-50118369392 ABOUT THE TALK Keras is a high-level open-source deep learning framework that by default works on top of TensorFlow. Keras is minimalistic, efficient and highly flexible because it works with a modular layer system to define, compile and fit neural networks. It ... Read More

Feed: R-bloggers. Author: Adnan Fiaz. Nowadays whenever I do my work in R there is a constant nagging voice in the back of my head telling me “you should do this in Python”. And when I do my work in Python it’s telling me “you can do this faster in R”. So when the reticulate package came out I was overjoyed and in this blogpost I will explain to you why. re-tic-u-late (rĭ-tĭkˈyə-lĭt, -lātˌ) So what exactly does reticulate do? It’s goal is to facilitate interoperability between Python and R. It does this by embedding a Python session within the R session which enables ... Read More
